Significant Accounting Policies [Abstract] | |
Significant Accounting Policies | 1. Significant Accounting Policies The primary business of The York Water Company, or the Company, is to impound, purify and distribute water. The Company also operates three wastewater collection and two treatment systems. The Company operates within its franchised territory located in York and Adams Counties, Pennsylvania, and is subject to regulation by the Pennsylvania Public Utility Commission, or PPUC. The following summarizes the significant accounting policies employed by The York Water Company. Utility Plant and Depreciation The cost of additions includes contracted cost, direct labor and fringe benefits, materials, overhead and, for certain utility plant, allowance for funds used during construction. In accordance with regulatory accounting requirements, water and wastewater systems acquired are recorded at estimated original cost of utility plant when first devoted to utility service and the applicable depreciation is recorded to accumulated depreciation. The difference between the estimated original cost less applicable accumulated depreciation, and the purchase price and acquisition costs is recorded as an acquisition adjustment within utility plant as permitted by the PPUC. At December 31, 2018 and 2017, utility plant includes a net credit acquisition adjustment of $3,108 and $3,234, respectively. For those amounts approved by the PPUC, the net acquisition adjustment is being amortized over the remaining life of the respective assets. Certain amounts are still awaiting approval from the PPUC before amortization will commence. Amortization amounted to $58 in each of the two years in the period ended December 31, 2018. Upon normal retirement of depreciable property, the estimated or actual cost of the asset is credited to the utility plant account, and such amounts, together with the cost of removal less salvage value, are charged to the reserve for depreciation. To the extent the Company recovers cost of removal or other retirement costs through rates after the retirement costs are incurred, a regulatory asset is reported. Gains or losses from abnormal retirements are reflected in income currently. The straight-line remaining life method is used to compute depreciation on utility plant cost, exclusive of land and land rights. Annual provisions for depreciation of transportation and mechanical equipment included in utility plant are computed on a straight-line basis over the estimated service lives. Such provisions are charged to clearing accounts and apportioned therefrom to operating expenses and other accounts in accordance with the Uniform System of Accounts as prescribed by the PPUC. The Company charges to maintenance expense the cost of repairs and replacements and renewals of minor items of property. Maintenance of transportation equipment is charged to clearing accounts and apportioned therefrom in a manner similar to depreciation. The cost of replacements, renewals and betterments of units of property is capitalized to the utility plant accounts. The following remaining lives are used for financial reporting purposes: December 31, Approximate range Utility Plant Asset Category 2018 2017 of remaining lives Mains and accessories $ 190,679 $ 182,927 11 – 86 years Services, meters and hydrants 74,178 71,183 18 – 52 years Operations structures, reservoirs and water tanks 61,868 53,610 9 – 59 years Pumping and treatment equipment 32,575 29,814 8 – 31 years Office, transportation and operating equipment 13,531 12,787 3 – 24 years Land and other non-depreciable assets 3,202 3,196 - Utility plant in service 376,033 353,517 Construction work in progress 4,751 12,250 - Total Utility Plant $ 380,784 $ 365,767 The effective rate of depreciation was 2.21% in 2018 and 2.26% in 2017 on average utility plant, net of customers' advances and contributions. Larger depreciation provisions resulting from allowable accelerated methods are deducted for tax purposes. Cash and Cash Equivalents For the purposes of the statements of cash flows, the Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents except for those instruments earmarked to fund construction expenditures or repay long-term debt. The Company periodically maintains cash balances in major financial institutions in excess of the federally insured limit by the Federal Deposit Insurance Corporation (FDIC). The Company has not experienced any losses and believes it is not exposed to any significant credit risk on cash and cash equivalents. Accounts Receivable Accounts receivable are stated at outstanding balances, less a reserve for doubtful accounts. The reserve for doubtful accounts is established through provisions charged against income. Accounts deemed to be uncollectible are charged against the reserve and subsequent recoveries, if any, are credited to the reserve. The reserve for doubtful accounts is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management's periodic evaluation of the adequacy of the reserve is based on past experience, agings of the receivables, adverse situations that may affect a customer's ability to pay, current economic conditions, and other relevant factors. This evaluation is inherently subjective. Unpaid balances remaining after the stated payment terms are considered past due. Materials and Supplies Inventories Materials and supplies inventories are stated at cost. Costs are determined using the average cost method. Note Receivable Note receivable is recorded at cost and represent amounts due from a municipality for construction of water mains in their municipality. Management, considering current information and events regarding the borrowers' ability to repay their obligations, considers a note to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the note agreement. When a note is considered to be impaired, the carrying value of the note is written down. The amount of the impairment is measured based on the present value of expected future cash flows discounted at the note's effective interest rate. Regulatory Assets and Liabilities The Company is subject to the provisions of generally accepted accounting principles regarding rate-regulated entities. The accounting standards provide for the recognition of regulatory assets and liabilities as allowed by regulators for costs or credits that are reflected in current customer rates or are considered probable of being included in future rates. The regulatory assets or liabilities are then relieved as the cost or credit is reflected in rates. Regulatory assets represent costs that are expected to be fully recovered from customers in future rates while regulatory liabilities represent amounts that are expected to be refunded to customers in future rates. These deferred costs have been excluded from the Company’s rate base and, therefore, no return is being earned on the unamortized balances. Regulatory assets and liabilities are comprised of the following: December 31, Remaining Recovery 2018 2017 Periods Assets Income taxes $ 21,432 $ 18,564 Various Postretirement benefits 3,071 5,382 5 – 10 years Unrealized swap losses 1,799 2,172 1 – 11 years Utility plant retirement costs 4,841 3,994 5 years Customer-owned lead service line replacements 304 191 4 years Income taxes on customers' advances for construction and contributions in aid of construction 577 - Various Service life study expenses 18 23 4 years Rate case filing expenses 311 5 3 years $ 32,353 $ 30,331 Liabilities Excess accumulated deferred income taxes on accelerated depreciation $ 14,184 $ 14,348 Various Income taxes 6,979 6,260 Various IRS TPR catch-up deduction 3,887 3,887 15 years Revenue reduction for tax rate change 1,764 - 2 years $ 26,814 $ 24,495 The regulatory asset for income taxes includes (a) deferred state income taxes related primarily to differences between book and tax depreciation expense, (b) deferred income taxes related to the differences that arise between specific asset improvement costs capitalized for book purposes and deducted as a repair expense for tax purposes, and (c) deferred income taxes associated with the gross-up of revenues related to the differences. These assets are recognized for ratemaking purposes on a cash or flow-through basis and will be recovered in rates as they reverse. Postretirement benefits include the difference between contributions and deferred pension expense and the underfunded status of the pension plans. The underfunded status represents the difference between the projected benefit obligation and the fair market value of the assets. This asset is expected to be recovered in future years as additional contributions are made or markets continue to generate positive returns. The recovery period is dependent on contributions made to the plans, plan asset performance and the discount rate used to value the obligations. The period is estimated at between 5 and 10 years. The Company uses regulatory accounting treatment to defer the mark-to-market unrealized gains and losses on its interest rate swap to reflect that the gain or loss is included in the ratemaking formula when the transaction actually settles. The value of the swap as of the balance sheet date is recorded as part of other deferred credits. Realized gains or losses on the swap will be recorded as interest expense in the statement of income over its remaining life of 11 years. Utility plant retirement costs represents costs already incurred for the removal of assets, which are expected to be recovered over a five-year period in rates, through depreciation expense. The Company was granted approval by the PPUC to modify its tariff to replace lead customer-owned service lines that are discovered when the Company replaces its lead service lines over the remaining three years, and to include the cost of the annual replacement of up to 400 lead customer-owned service lines whenever they are discovered, regardless of the material used for the company-owned service line over nine years. The tariff modification allows the Company to replace customer-owned service lines at its own initial cost and record the costs as a regulatory asset to be recovered in future base rates to customers. The recovery period was established in the most recent rate order at four years. Service life study expenses are deferred and amortized over their remaining life of four years. Rate case filing expenses are deferred and amortized over their life of three years. Pursuant to the Tax Cuts and Jobs Act of 2017, or 2017 Tax Act, customers’ advances for construction and contributions in aid of construction are considered taxable income. The Company’s tariff allows the Company to record these income taxes for inclusion in rate base. This asset is recognized for ratemaking purposes on a cash or flow-through basis and will be recovered in rates as it reverses. Under normalization rules applicable to public utility property included in the 2017 Tax Act, the excess accumulated deferred income taxes on accelerated depreciation from lowering of the enacted federal statutory corporate tax rate is recorded as a regulatory liability. The benefit will be given back to customers in rates over the remaining regulatory life of the property. The regulatory liability for income taxes includes deferred taxes related to excess accumulated deferred income taxes on accelerated depreciation, other postretirement benefits, customers’ advances for construction and contributions in aid of construction, and bad debts, as well as deferred investment tax credits. These liabilities will be given back to customers in rates, as tax deductions occur over the next 1 to 50 years. The regulatory liability for the Internal Revenue Service, or IRS, tangible property regulations, or TPR, catch-up deduction represents the tax benefits realized on the Company’s 2014 income tax return for qualifying capital expenditures made prior to 2014. The Company received approval from the PPUC in its most recent rate order to amortize the catch-up deduction over 15 years beginning March 1, 2019. Pursuant to a rate order approved by the PPUC, the Company has agreed to return the 2018 income tax savings pursuant to the 2017 Tax Act, the associated tax gross-up, and the excess accumulated deferred income taxes on accelerated depreciation to customers as a reconcilable negative surcharge on bills. The liability will be given back to customers as a negative surcharge on bills over one year beginning March 1, 2019. Other Assets Other assets consist mainly of the cash value of life insurance policies held as an investment by the Company for reimbursement of costs and benefits associated with its supplemental retirement and deferred compensation programs. Deferred Debt Expense Deferred debt expense is amortized on a straight-line basis over the term of the related debt and is presented on the balance sheet as a direct reduction from long-term debt. Customers' Advances for Construction Customer advances are cash payments from developers, municipalities, customers or builders for construction of utility plant, and are refundable upon completion of construction, as operating revenues are earned. If the Company loans funds for construction to the customer, the refund amount is credited to the note receivable rather than paid out in cash. After all refunds to which the customer is entitled are made, any remaining balance is transferred to contributions in aid of construction. Contributions in Aid of Construction Contributions in Aid of Construction is composed of (i) direct, non-refundable contributions from developers, customers or builders for construction of water infrastructure and (ii) customer advances that have become non-refundable. Contributions in aid of construction are deducted from the Company’s rate base, and therefore, no return is earned on property financed with contributions. The PPUC requires that contributions received remain on the Company’s balance sheets indefinitely as a long-term liability. Interest Rate Swap Agreement The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is interest rate risk. The Company utilizes an interest rate swap agreement to convert its variable-rate debt to a fixed rate. Interest rate swaps are contracts in which a series of interest rate cash flows are exchanged over a prescribed period. The notional amount on which the interest payments are based is not exchanged. The Company has designated the interest rate swap agreement as a cash flow hedge, classified as a financial derivative used for non-trading activities. The accounting standards regarding accounting for derivatives and hedging activities require companies to recognize all derivative instruments as either assets or liabilities at fair value on the balance sheets. In accordance with the standards, the interest rate swap is recorded on the balance sheets in other deferred credits at fair value. The Company uses regulatory accounting treatment rather than hedge accounting to defer the unrealized gains and losses on its interest rate swap. Instead of the effective portion being recorded as other comprehensive income and the ineffective portion being recognized in earnings, the entire unrealized swap value is recorded as a regulatory asset. Based on current ratemaking treatment, the Company expects the gains and losses to be recognized in rates and in interest expense as the swap settlements occur. Swap settlements are recorded in the income statement with the hedged item as interest expense. Swap settlements resulted in the reclassification from regulatory assets to interest expense of $236 in 2018 and $301 in 2017. The overall swap result was a (gain) loss of $(137) in 2018 and $209 in 2017. During the twelve months ending December 31, 2019, the Company expects to reclassify $199 (before tax) from regulatory assets to interest expense. The interest rate swap will expire on October 1, 2029. Stock-Based Compensation The Company records compensation expense in the financial statements for stock-based awards based on the grant date fair value of those awards. Stock-based compensation expense is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Forfeitures are recognized as they occur. Income Taxes Certain income and expense items are accounted for in different time periods for financial reporting than for income tax reporting purposes. Deferred income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. To the extent such income taxes increase or decrease future rates, an offsetting regulatory asset or liability has been recorded. Investment tax credits have been deferred and are being amortized to income over the average estimated service lives of the related assets. As of December 31, 2018 and 2017, deferred investment tax credits amounted to $578 and $618, respectively. The Company filed for a change in accounting method under the IRS TPR effective in 2014. Under the change in accounting method, the Company is permitted to deduct the costs of certain asset improvements that were previously being capitalized and depreciated for tax purposes as an expense on its income tax return. The Company is permitted to make this deduction for prior years (the “catch-up deduction”) and each year going forward, beginning with 2014 (the “ongoing deduction”). The ongoing deduction results in a reduction in the effective income tax rate, a net reduction in income tax expense, and a reduction in the amount of income taxes currently payable. The catch-up deduction resulted in a decrease in current income taxes payable and an increase to regulatory liabilities. The Company received approval from the PPUC in its most recent rate order to amortize the catch-up deduction, recorded as a regulatory liability, over 15 years beginning March 1, 2019. Both the ongoing and catch-up deductions resulted in increases to deferred tax liabilities and regulatory assets representing the appropriate book and tax basis difference on capital additions. The 2017 Tax Act, among other things, reduces the federal statutory corporate tax rate for tax years beginning in 2018 from 34% to 21%, eliminates certain deductions, and eliminates bonus depreciation on qualified water and wastewater property. This resulted in the remeasurement of the federal portion of the Company’s deferred taxes as of December 31, 2017 to the 21% rate. The effect was recognized in income for the year ended December 31, 2017 for all deferred tax assets and liabilities except accelerated depreciation. Under normalization rules applicable to public utility property included in the 2017 Tax Act, the excess accumulated deferred income taxes on accelerated depreciation is recorded as a regulatory liability. The regulatory liability is a temporary difference so a deferred tax asset is recorded including the gross-up of revenue necessary to return, in rates, the effect of the temporary difference. Allowance for Funds Used During Construction Allowance for funds used during construction (AFUDC) represents the estimated cost of funds used for construction purposes during the period of construction. These costs are reflected as non-cash income during the construction period and as an addition to the cost of plant constructed. AFUDC includes the net cost of borrowed funds and a rate of return on other funds. The PPUC approved rate of 10.04% was applied for 2018 and 2017. AFUDC is recovered through water and wastewater rates as utility plant is depreciated. Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Reclassifications Certain 2017 amounts have been reclassified to conform to the 2018 presentation. Such reclassifications had no effect on the balance sheets, net income, the statements of common stockholders’ equity, or the statements of cash flows. Impact of Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost . This ASU requires employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net benefit costs will be presented in the income statement separately from the service cost and outside of a subtotal of income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption available. The Company adopted the standard on January 1, 2018. The adoption of this standard resulted in the reclassification on the statements of income of the components of net periodic pension cost other than service cost from operating expenses to other pension costs in other income (expenses) of $1,285 and $1,220 for the years ended , 2018 and 2017, respectively. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments. The Company adopted the standard on January 1, 2018. The adoption did not have an impact on its financial position, results of operations and cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers.

Acquisitions | 2. Acquisitions On January 6, 2017, the Company completed the acquisition of the water assets of Stockham's Village Mobile Home Park in Adams County, Pennsylvania. The Company began operating the existing system through an interconnection with its current distribution system on January 9, 2017. The acquisition resulted in the addition of approximately 80 new water customers with purchase price and acquisition costs of approximately $24,which is more than the depreciated original cost of the assets. The Company recorded an acquisition adjustment of approximately $17 and will seek approval from the PPUC, to amortize the acquisition adjustment over the remaining life of the acquired assets. On February 23, 2017, the Company completed the acquisition of the wastewater collection assets of West York Borough in York County, Pennsylvania. The Company began operating the existing collection facilities on February 27, 2017. The acquisition resulted in the addition of approximately 1,700 wastewater customers, representing more than 2,200 units, with purchase price and acquisition costs of approximately $448, which is more than the depreciated original cost of the assets. The Company recorded an acquisition adjustment of approximately $358 and will seek approval from the PPUC to amortize the acquisition adjustment over the remaining life of the acquired assets. |

Accounts Receivable and Contract Assets | 3. Accounts Receivable and Contract Assets Accounts receivable and contract assets are summarized in the following table: As of As of Dec. 31, 2018 Dec. 31, 2017 Change Accounts receivable – customers $ 4,731 $ 4,661 $ 70 Other receivables 385 191 194 5,116 4,852 264 Less: allowance for doubtful accounts (305 ) (305 ) – Accounts receivable, net $ 4,811 $ 4,547 $ 264 Unbilled revenue $ 2,427 $ 2,459 $ (32 ) Differences in timing of revenue recognition, billings, and cash collections result in receivables and contract assets. Generally, billing occurs subsequent to revenue recognition, resulting in a contract asset reported as unbilled revenue on the balance sheet. The Company does not receive advances or deposits from customers before revenue is recognized so no contract liabilities are reported. Accounts receivable are recorded when the right to consideration becomes unconditional and are presented separately on the balance sheet. The changes in accounts receivable – customers and in unbilled revenue were primarily due to normal timing difference between performance and the customer’s payments. |

Note Receivable and Customers' Advances for Construction | 4. Note Receivable and Customers' Advances for Construction The Company entered into an agreement with a municipality to extend water service into a previously formed water district. The Company loaned funds to the municipality to cover the costs related to the project. The municipality concurrently advanced these funds back to the Company in the form of customers' advances for construction. The municipality is required by enacted ordinance to charge application fees and water revenue surcharges (fees) to customers connected to the system, which are remitted to the Company. The note principal and the related customer advance are reduced periodically as operating revenues are earned by the Company from customers connected to the system and refunds of the advance are made. There is no due date for the notes or expiration date for the advance. The Company recorded interest income of $105 in 2018 and $98 in 2017. The interest rate on the note outstanding is 7.5%. Included in the accompanying balance sheets at December 31, 2018 and 2017 were the following amounts related to this project. 2018 2017 Note receivable, including interest $ 255 $ 255 Customers' advances for construction 305 306 The Company has other customers' advances for construction totaling $6,544 and $6,018 at December 31, 2018 and 2017, respectively. |

Common Stock and Earnings Per Share | 5. Common Stock and Earnings Per Share Net income of $13,376 and $12,974 for the years ended December 31, 2018 and 2017 respectively, is used to calculate both basic and diluted earnings per share. Basic net income per share is based on the weighted average number of common shares outstanding. Diluted net income per share is based on the weighted average number of common shares outstanding plus potentially dilutive shares. The dilutive effect of employee stock-based compensation is included in the computation of diluted net income per share. The dilutive effect of stock-based compensation is calculated using the treasury stock method and expected proceeds upon exercise or issuance of the stock-based compensation. The following table summarizes the shares used in computing basic and diluted net income per share: 2018 2017 Weighted average common shares, basic 12,903,568 12,849,123 Effect of dilutive securities: Employee stock-based compensation 268 48 Weighted average common shares, diluted 12,903,836 12,849,171 Under the employee stock purchase plan, all full-time employees who have been employed at least ninety consecutive days may purchase shares of the Company's common stock limited to 10% of gross compensation. The purchase price is 95% of the fair market value (as defined). Shares issued during 2018 and 2017 were 5,187 and 4,770, respectively. As of December 31, 2018, 65,639 authorized shares remain unissued under the plan. The Company has a Dividend Reinvestment and Direct Stock Purchase and Sale Plan (“the Plan”), which is available to both current shareholders and the general public. On October 3, 2016, the Company filed a Registration Statement on Form S-3 with the Securities and Exchange Commission (SEC) to authorize an additional 331,000 shares and rollover the unissued 170,240 shares authorized under the 2013 Form S-3, for issuance under the new Prospectus for the Plan. Under the optional dividend reinvestment portion of the Plan, holders of the Company's common stock may purchase additional shares instead of receiving cash dividends. The purchase price is 95% of the fair market value (as defined). Under the direct stock purchase portion of the Plan, purchases are made monthly at 100% of the stock’s fair market value, as defined in the new Prospectus. The Registration Statement was declared effective by the SEC on November 16, 2016. Shares issued during 2018 and 2017 were 61,864 and 51,401, respectively. As of December 31, 2018, 379,374 authorized shares remain unissued under the plan. On March 11, 2013, the Board of Directors, or the Board, authorized a share repurchase program granting the Company authority to repurchase up to 1,200,000 shares of the Company’s common stock from time to time. The stock repurchase program has no specific end date and the Company may repurchase shares in the open market or through privately negotiated transactions. The Company may suspend or discontinue the repurchase program at any time. During 2018 and 2017, the Company repurchased and retired 0 and 37,229 shares, respectively. As of December 31, 2018, 618,004 shares remain available for repurchase. |

Long-Term Debt and Short-Term Borrowings Long-term debt as of December 31, 2018 and 2017 is summarized in the following table: 2018 2017 10.17% Senior Notes, Series A, due 2019 $ 6,000 $ 6,000 9.60% Senior Notes, Series B, due 2019 5,000 5,000 1.00% Pennvest Note, due 2019 30 74 10.05% Senior Notes, Series C, due 2020 6,500 6,500 8.43% Senior Notes, Series D, due 2022 7,500 7,500 Variable Rate Pennsylvania Economic Development Financing Authority Exempt Facilities Revenue Bonds, Series 2008A, due 2029 12,000 12,000 4.75% York County Industrial Development Authority Revenue Bonds, Series 2006, due 2036 10,500 10,500 4.50% Pennsylvania Economic Development Financing Authority Exempt Facilities Revenue Refunding Bonds, Series 2014, due 2038 14,870 14,870 5.00% Monthly Senior Notes, Series 2010A, due 2040 15,000 15,000 4.00% - 4.50% York County Industrial Development Authority Exempt Facilities Revenue Bonds, Series 2015, due 2029 - 2045 10,000 10,000 Committed Line of Credit, due 2020 8,508 5,389 Total long-term debt 95,908 92,833 Less discount on issuance of long-term debt (204 ) (215 ) Less unamortized debt issuance costs (2,346 ) (2,476 ) Less current maturities (30 ) (44 ) Long-term portion $ 93,328 $ 90,098 Payments due by year as of December 31, 2018: 2019 2020 2021 2022 2023 $ 30 $ 27,008 $ – $ 7,500 $ – Payments due in 2020 include payback of the committed line of credit. The committed line of credit is reviewed annually, and upon favorable outcome, would likely be extended for another year. Payments due in 2020 also include potential payments of $12,000 on the variable rate bonds (due 2029) which would only be payable if all bonds were tendered and could not be remarketed, or in the event the Company was unable to, or chose not to, renew the letter of credit backing the bonds. There is currently no such indication of this happening. The 10.17% Senior Notes, Series A and 9.60% Senior Notes, Series B are not included in current maturities as they have been refinanced with 4.54% Senior Notes, Series 2019 issued January 31, 2019. See Note 15 for additional information regarding this issue. As such, they are not included in payments due in 2019. Fixed Rate Long-Term Debt The Pennsylvania Economic Development Financing Authority, or PEDFA, Series 2014 Bonds contain both optional and special redemption provisions. Under the optional provisions, the Company can redeem all or a portion of the bonds on or after May 1, 2019. Under the special provisions, representatives of deceased beneficial owners of the bonds have the right to request redemption prior to the stated maturity of all or part of their interest in the bonds beginning on or after May 1, 2014. The Company is not obligated to redeem any individual interest exceeding $25, or aggregate interest exceeding $300, in any annual period. In 2018 and 2017, no bonds were retired under these provisions. Currently, no additional bonds that meet the special provisions have been tendered for redemption. Variable Rate Long-Term Debt On May 7, 2008, the PEDFA issued $12,000 aggregate principal amount of PEDFA Exempt Facilities Revenue Refunding Bonds, Series A of 2008 (the "Series A Bonds") for the Company's benefit pursuant to the terms of a trust indenture, dated as of May 1, 2008, between the PEDFA and Manufacturers and Traders Trust Company, as trustee. The PEDFA then loaned the proceeds of the offering of the Series A Bonds to the Company pursuant to a loan agreement, dated as of May 1, 2008, between the Company and the PEDFA. The loan agreement provides for a $12,000 loan with a maturity date of October 1, 2029. Amounts outstanding under the loan agreement are the Company’s direct general obligations. The proceeds of the loan were used to redeem the PEDFA Exempt Facilities Revenue Bonds, Series B of 2004 (the “2004 Series B Bonds”). The 2004 Series B Bonds were redeemed because the bonds were tendered and could not be remarketed due to the downgrade of the bond insurer’s credit rating. Borrowings under the loan agreement bear interest at a variable rate as determined by PNC Capital Markets, as remarketing agent, on a periodic basis elected by the Company, which has currently elected that the interest rate be determined on a weekly basis. The remarketing agent determines the interest rate based on the current market conditions in order to determine the lowest interest rate which would cause the Series A Bonds to have a market value equal to the principal amount thereof plus accrued interest thereon. The variable interest rate under the loan agreement averaged 1.46% in 2018 and 0.88% in 2017. As of December 31, 2018 and 2017, the interest rate was 1.75% and 1.78%, respectively. The holders of the $12,000 Series A Bonds may tender their bonds at any time. When the bonds are tendered, they are subject to an annual remarketing agreement, pursuant to which a remarketing agent attempts to remarket the tendered bonds according to the terms of the indenture. In order to keep variable interest rates down and to enhance the marketability of the Series A Bonds, the Company entered into a Reimbursement, Credit and Security Agreement with PNC Bank, National Association (“the Bank”) dated as of May 1, 2008. This agreement provides for a direct pay letter of credit issued by the Bank to the trustee for the Series A Bonds. The Bank is responsible for providing the trustee with funds for the timely payment of the principal and interest on the Series A Bonds and for the purchase price of the Series A Bonds that have been tendered or deemed tendered for purchase and have not been remarketed. The Company’s responsibility is to reimburse the Bank the same day as regular interest payments are made, and within fourteen months for the purchase price of tendered bonds that have not been remarketed. The reimbursement period for the principal is immediate at maturity, upon default by the Company, or if the Bank does not renew the Letter of Credit. The current expiration date of the Letter of Credit is June 30, 2020. It is reviewed annually for a potential extension of the expiration date. The Company may elect to have the Series A Bonds redeemed, in whole or in part, on any date that interest is payable for a redemption price equal to the principal amount thereof plus accrued interest to the date of redemption. The Series A Bonds are also subject to mandatory redemption for the same redemption price in the event that the IRS determines that the interest payable on the Series A Bonds is includable in gross income of the holders of the bonds for federal tax purposes. Interest Rate Swap Agreement In connection with the issuance of the PEDFA 2004 Series B Bonds, the Company entered into an interest rate swap agreement with a counterparty, in the notional principal amount of $12,000. The Company elected to retain the swap agreement for the 2008 Series A Bonds. Interest rate swap agreements derive their value from underlying interest rates. These transactions involve both credit and market risk. The notional amounts are amounts on which calculations, payments, and the value of the derivative are based. Notional amounts do not represent direct credit exposure. Direct credit exposure is limited to the net difference between the calculated amounts to be received and paid, if any. Such difference, which represents the fair value of the swap, is reflected on the Company’s balance sheets. See Note 7 for additional information regarding the fair value of the swap. The interest rate swap will terminate on the maturity date of the 2008 Series A Bonds (which is the same date as the maturity date of the loan under the loan agreement), unless sooner terminated pursuant to its terms. In the event the interest rate swap terminates prior to the maturity date of the 2008 Series A Bonds, either the Company or the swap counterparty may be required to make a termination payment to the other based on market conditions at such time. The Company is exposed to credit-related losses in the event of nonperformance by the counterparty. The Company controls the credit risk of its financial contracts through credit approvals, limits and monitoring procedures, and does not expect the counterparty to default on its obligations. Notwithstanding the terms of the swap agreement, the Company is ultimately obligated for all amounts due and payable under the loan agreement. The interest rate swap agreement contains provisions that require the Company to maintain a credit rating of at least BBB- with Standard & Poor’s. On February 9, 2018, Standard & Poor’s affirmed the Company’s credit rating at A-, with a stable outlook and adequate liquidity. If the Company’s rating were to fall below this rating, it would be in violation of these provisions, and the counterparty to the derivative could request immediate payment if the derivative was in a liability position. The Company’s interest rate swap was in a liability position as of December 31, 2018. If a violation was triggered on December 31, 2018, the Company would have been required to pay the counterparty approximately $1,852. The Company's interest rate swap agreement provides that it pays the counterparty a fixed interest rate of 3.16% on the notional amount of $12,000. In exchange, the counterparty pays the Company a floating interest rate (based on 59% of the U.S. Dollar one-month LIBOR rate) on the notional amount. The floating interest rate paid to the Company is intended, over the term of the swap, to approximate the variable interest rate on the loan agreement and the interest rate paid to bondholders, thereby managing its exposure to fluctuations in prevailing interest rates. The Company's net payment rate on the swap averaged 1.97% in 2018 and 2.50% in 2017. As of December 31, 2018, there was a spread of 31 basis points between the variable rate paid to bondholders and the variable rate received from the swap counterparty, which equated to an overall effective rate of 3.47% (including variable interest and swap payments). As of December 31, 2017, there was a spread of 91 basis points which equated to an overall effective rate of 4.07% (including variable interest and swap payments). Line of Credit Borrowings As of December 31, 2018, the Company maintained unsecured lines of credit aggregating $41,500 with four banks. The first line of credit, in the amount of $13,000, is a committed line of credit with a revolving 2-year maturity (currently May 2020) and carries an interest rate of LIBOR plus 1.20%. The Company had $6,508 and $5,389 outstanding under this line of credit as of December 31, 2018 and 2017, respectively. The second line of credit, in the amount of $11,000, is a committed line of credit, which matures in May 2020 and carries an interest rate of LIBOR plus 1.25%. The third line of credit, in the amount of $7,500, is a committed line of credit, which matures in June 2020 and carries an interest rate of LIBOR plus 1.15%. The Company had $2,000 outstanding under this line of credit as of December 31, 2018. The fourth line of credit, in the amount of $10,000, is a committed line of credit, which matures in September 2019 and carries an interest rate of LIBOR plus 1.20%. The Company had $1,000 outstanding under this line of credit as of December 31, 2018 and 2017. Average borrowings outstanding under the lines of credit were $7,206 in 2018 and $3,132 in 2017. The average cost of borrowings under the lines of credit was 3.20% during 2018 and 1.76% during 2017. The weighted average interest rate on the line of credit borrowings was 3.60% as of December 31, 2018 and 2.65% as of December 31, 2017. Debt Covenants and Restrictions The terms of the debt agreements carry certain covenants and limit in some cases the Company's ability to borrow additional funds, to prepay its borrowings and include certain restrictions with respect to declaration and payment of cash dividends and the Company's acquisition of its stock. Under the terms of the most restrictive agreements, the Company cannot borrow in excess of 60% of its utility plant, and cumulative payments for dividends and acquisition of stock since December 31, 1982 may not exceed $1,500 plus net income since that date. As of December 31, 2018, none of the earnings retained in the business are restricted under these provisions. The Company's Pennvest Loan, which will mature in 2019, is secured by $800 of receivables. Other than this loan, the Company's debt is unsecured. The Company's lines of credit require it to maintain a minimum equity to total capitalization ratio (defined as the sum of equity plus funded debt) and a minimum interest coverage ratio (defined as net income plus interest expense plus income tax expense divided by interest expense). As of December 31, 2018, the Company was in compliance with these covenants. |

Fair Value of Financial Instruments [Abstract] | |
Fair Value of Financial Instruments | 7. Fair Value of Financial Instruments The accounting standards regarding fair value measurements establish a fair value hierarchy which indicates the extent to which inputs used in measuring fair value are observable in the market. Level 1 inputs include quoted prices for identical instruments and are the most observable. Level 2 inputs include quoted prices for similar assets and observable inputs such as interest rates, commodity rates and yield curves. Level 3 inputs are not observable in the market and include management’s own judgments about the assumptions market participants would use in pricing the asset or liability. The Company has recorded its interest rate swap liability at fair value in accordance with the standards. The liability is recorded under the caption “Other deferred credits” on the balance sheets. The table below illustrates the fair value of the interest rate swap as of the end of the reporting period. Description December 31, 2018 Fair Value Measurements at Reporting Date Using Significant Other Observable Inputs (Level 2) Interest Rate Swap $1,815 $1,815 Fair values are measured as the present value of all expected future cash flows based on the LIBOR-based swap yield curve as of the date of the valuation. These inputs to this calculation are deemed to be Level 2 inputs. The balance sheet carrying value reflects the Company's credit quality as of December 31, 2018. The rate used in discounting all prospective cash flows anticipated to be made under this swap reflects a representation of the yield to maturity for 30-year debt on utilities rated A- as of December 31, 2018. The use of the Company's credit quality resulted in a reduction in the swap liability of $37 as of December 31, 2018. The fair value of the swap reflecting the Company's credit quality as of December 31, 2017 is shown in the table below. Description December 31, 2017 Fair Value Measurements at Reporting Date Using Significant Other Observable Inputs (Level 2) Interest Rate Swap $2,196 $2,196 The carrying amount of current assets and liabilities that are considered financial instruments approximates fair value as of the dates presented. The Company's total long-term debt, with a carrying value of $95,908 at December 31, 2018, and $92,833 at December 31, 2017, had an estimated fair value of approximately $105,000 and $108,000, respectively. The estimated fair value of debt was calculated using a discounted cash flow technique that incorporates a market interest yield curve with adjustments for duration and risk profile. These inputs to this calculation are deemed to be Level 2 inputs. The Company recognized its credit rating in determining the yield curve, and did not factor in third party credit enhancements including bond insurance on the 2006 York County Industrial Development Authority issue and the letter of credit on the 2008 PEDFA Series A issue. Customers' advances for construction and note receivable have carrying values at December 31, 2018 of $6,849 and $255, respectively. At December 31, 2017, customers' advances for construction and note receivable had carrying values of $6,324 and $255, respectively. The relative fair values of these amounts cannot be accurately estimated since the timing of future payment streams is dependent upon several factors, including new customer connections, customer consumption levels and future rate increases. |

Commitments [Abstract] | |
Commitments | 8. Commitments Based on its capital budget, the Company anticipates construction and acquisition expenditures for 2019 and 2020 of approximately $21,479 and $21,209, respectively, exclusive of any acquisitions not yet approved. The Company plans to finance ongoing capital expenditures with internally-generated funds, borrowings against the Company’s lines of credit, proceeds from the issuance of common stock under its dividend reinvestment and direct stock purchase and sale plan and ESPP, potential common stock or debt issues and customer advances and contributions. The Company entered into a consent order agreement with the Pennsylvania Department of Environmental Protection in December 2016 after the Company determined it exceeded the action level for lead as established by the Lead and Copper Rule, or LCR, issued by the U.S. Environmental Protection Agency. Under the agreement, the Company committed to exceed the LCR replacement schedule by replacing all of the remaining known company-owned lead service lines within four years from the agreement. The cost for these service line replacements was approximately $2,341 through December 31, 2018 and is included in utility plant. As of December 31, 2018, all known company-owned lead service lines have been replaced. Any additional company-owned, lead service lines that are discovered will be replaced but are not expected to have a material impact on the financial position of the Company. Due to its exceedance in 2016, the Company was required under the LCR to complete two rounds of compliance testing at the customer’s tap in 2017. The water samples did not exceed the action level either time. As a result, the Company was able to reduce its monitoring to annual compliance tests beginning in 2018. The Company completed its compliance testing at the customer’s tap in 2018 and the water samples did not exceed the action level. In addition, the Company performed in excess of the required actions under the LCR. Specifically, the Company provided the affected customers with a free water test and a 200 gallon per month credit to flush their line in order to reduce any lead content until their lead service line has been replaced. The cost of the water tests and flushing credits was $4 and $16 for the years ended December 31, 2018 and 2017, respectively. Additional amounts for water tests and flushing credits are not expected to have a material impact on the financial position of the Company. The Company was granted approval by the PPUC to modify its tariff to include the cost of the replacement of lead customer-owned service lines that are discovered when the Company replaces its lead service lines, and to include the cost of the annual replacement of up to 400 lead customer-owned service lines whenever they are discovered, regardless of the material used for the company-owned service line over nine years from the agreement. The tariff modification allows the Company to replace customer-owned service lines at its own initial cost. The Company will record the costs as a regulatory asset to be recovered in future base rates to customers, over a four-year period. The cost for the customer-owned lead service line replacements under the four-year tariff modification was approximately $304 through December 31, 2018 and is included as a regulatory asset. All known customer-owned lead service lines that are connected to a company-owned lead service line have been replaced by December 31, 2018. Based on its experience, the Company estimates that lead customer-owned service lines replacements will cost $910 under the nine-year tariff modification. This estimate is subject to adjustment as more facts become available. As of December 31, 2018, approximately 35% of the Company's full time employees are under union contract. The current contract was ratified in December 2017 and expires on April 30, 2020. The Company is involved in certain legal and administrative proceedings before various courts and governmental agencies concerning water service and other matters. The Company expects that the ultimate disposition of these proceedings will not have a material effect on the Company's financial position, results of operations and cash flows. |

Revenue The following table shows the Company’s revenues disaggregated by service and customer type. 2018 2017 Water utility service: Residential $ 30,348 $ 30,417 Commercial and industrial 13,351 13,538 Fire protection 2,931 2,968 Wastewater utility service: Residential 933 840 Commercial and industrial 227 191 Billing and revenue collection services 64 63 Collection services 54 62 Other revenue 22 38 Total Revenue from Contracts with Customers 47,930 48,117 Rents from regulated property 507 472 Total Operating Revenue $ 48,437 $ 48,589 Utility Service The Company provides utility service as a distinct and single performance obligation to each of its water and wastewater customers. The transaction price is detailed in the tariff pursuant to an order by the PPUC and made publicly available. There is no variable consideration and no free service, special rates, or subnormal charges to any customer. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied over time through the continuous provision of utility service through a stand-ready obligation to perform and the transfer of water or the collection of wastewater through a series of distinct transactions that are identical in nature and have the same pattern of transfer to the customer. The Company uses an output method to recognize the utility service revenue over time. The stand-ready obligation is recognized through the passage of time in the form of a fixed charge and the transfer of water or the collection of wastewater is recognized at a per unit rate based on the actual or estimated flow through the meter. Each customer is invoiced every month and the invoice is due within twenty days. The utility service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. A contract asset for unbilled revenue is recognized for the passage of time and the actual or estimated usage from the latest meter reading to the end of the accounting period. The methodology is standardized and consistently applied to reduce bias and the need for judgment. Billing and Revenue Collection Service The Company provides billing and revenue collection service as distinct performance obligations to four municipalities within the service territory of the Company. The municipalities provide wastewater service to their residents and the Company acts as the billing and revenue collection agent for the municipalities. The transaction price is a fixed amount per bill prepared as established in the contract. There is no variable consideration. Due to the fact that both the billing performance obligation and the revenue collection performance obligation are materially complete by the end of the reporting period, the Company does not allocate the transaction price between the two performance obligations. The performance obligations are satisfied at a point in time when the bills are sent as the municipalities receive all the benefits and bears all of the risk of non-collection at that time. Each municipality is invoiced when the bills are complete and the invoice is due within thirty days. The billing and revenue collection service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. Collection Service The Company provides collection service as a distinct and single performance obligation to several municipalities within the service territory of the Company. The municipalities provide wastewater service to their residents. If those residents are delinquent in paying for their wastewater service, the municipalities request that the Company post for and shut off the supply of water to the premises of those residents. When the resident is no longer delinquent, the Company will restore water service to the premises. The transaction price for each posting, each shut off, and each restoration is a fixed amount as established in the contract. There is no variable consideration. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied at a point in time when the posting, shut off, or restoration is completed as the municipalities receive all the benefits in the form of payment or no longer providing wastewater service. Each municipality is invoiced periodically for the posting, shut offs, and restorations that have been completed since the last billing and the invoice is due within thirty days. The collection service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. A contract asset for unbilled revenue is recognized for postings, shut offs, and restorations that have been completed from the last billing to the end of the accounting period. Service Line Protection Plan The Company provides service line protection as a distinct and single performance obligation to current water customers that choose to participate. The transaction price is detailed in the plan’s terms and conditions and made publicly available. There is no variable consideration. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied over time through the continuous provision of service line protection through a stand-ready obligation to perform. The Company uses an output method to recognize the service line protection revenue over time. The stand-ready obligation is recognized through the passage of time. A customer has a choice to prepay for an entire year or to pay in advance each month. The service line protection plan has no returns or extended warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no material performance obligations remain unsatisfied as of the end of the reporting period. |

Rate Matters [Abstract] | |
Rate Matters | 10. Rate Matters From time to time, the Company files applications for rate increases with the PPUC and is granted rate relief as a result of such requests. The most recent rate request was filed by the Company on May 30, 2018, and sought an annual increase in water rates of $6,399 and an annual increase in wastewater rates of $289. Effective March 1, 2019, the PPUC authorized an increase in water rates designed to produce approximately $3,361 in additional annual revenues and an increase in wastewater rates designed to produce approximately $289 in additional annual revenues. The PPUC permits water utilities to collect a distribution system improvement charge, or DSIC. The DSIC allows the Company to add a charge to customers' bills for qualified replacement costs of certain infrastructure without submitting a rate filing. This surcharge mechanism typically adjusts periodically based on additional qualified capital expenditures completed or anticipated in a future period. The DSIC is capped at 5% of base rates, and is reset to zero when new base rates that reflect the costs of those additions become effective or when a utility's earnings exceed a regulatory benchmark. The DSIC reset to zero when the new base rates took effect March 1, 2019. On May 17, 2018, the PPUC, in conjunction with its review of the effects of the 2017 Tax Act, issued an order which directed utilities with pending rate cases, including the Company, to address the issues related to the 2017 Tax Act in the context of an overall review of the Company’s rates and rate structure in lieu of any immediate action. The PPUC expected the Company and the other interested parties to address the effect of the federal tax rate reduction on the rates charged during the rate case review, including whether a retroactive surcharge or other measure is necessary to account for the tax rate change that became effective January 1, 2018. As part of a rate order approved by the PPUC, the Company has agreed to return $2,117 to customers as a reconcilable negative surcharge on their bills generated from March 2019 through February 2020. Based on this agreement, the Company recorded a regulatory liability of $1,764 as of December 31, 2018 by reducing revenue by $1,600 for the year ended December 31, 2018 and recording the gross-up of revenue necessary to return, in rates, the effect of this temporary tax difference, and reclassified $164 from excess accumulated deferred income taxes on accelerated depreciation recorded at December 31, 2017. |

Employee Benefit Plans [Abstract] | |
Employee Benefit Plans | 11. Employee Benefit Plans Pensions The Company maintains a general and administrative and a union-represented defined benefit pension plan covering all of its employees hired prior to May 1, 2010. Employees hired after May 1, 2010 are eligible for an enhanced 401(k) plan rather than a defined benefit plan. The benefits under the defined benefit plans are based upon years of service and compensation near retirement. The Company amended its defined benefit pension plans in 2014, generally limiting the years of eligible service under the plans to 30 years. The Company's funding policy is to contribute annually the amount permitted by the PPUC to be collected from customers in rates, but in no case less than the minimum Employee Retirement Income Security Act (ERISA) required contribution. The following table sets forth the plans' funded status as of December 31, 2018 and 2017. The measurement of assets and obligations of the plans is as of December 31, 2018 and 2017. Obligations and Funded Status at December 31 2018 2017 Change in Benefit Obligation Pension benefit obligation beginning of year $ 44,636 $ 40,754 Service cost 1,015 1,080 Interest cost 1,515 1,592 Actuarial (gain) loss (4,140 ) 2,645 Benefit payments (1,515 ) (1,435 ) Pension benefit obligation end of year 41,511 44,636 Change in Plan Assets Fair value of plan assets beginning of year 41,439 35,467 Actual return on plan assets (1,600 ) 5,107 Employer contributions 2,300 2,300 Benefits paid (1,515 ) (1,435 ) Fair value of plan assets end of year 40,624 41,439 Funded Status of Plans at End of Year $ (887 ) $ (3,197 ) The accounting standards require that the funded status of defined benefit pension plans be fully recognized on the balance sheets. They also call for the unrecognized actuarial gain or loss, the unrecognized prior service cost and the unrecognized transition costs to be adjustments to shareholders’ equity (accumulated other comprehensive income). Due to a rate order granted by the PPUC, the Company is permitted under the accounting standards to defer the charges otherwise recorded in accumulated other comprehensive income as a regulatory asset. Management believes these costs will be recovered in future rates charged to customers. The liability for the funded status of the Company’s pension plans is recorded in “Deferred employee benefits” on its balance sheets. In 2018, the plans recognized a significant actuarial gain. The Company adopted the new mortality improvement scale (MP-2018) but recognized a 60 basis point increase in the discount rate. In 2017, the plans recognized a significant actuarial loss. The Company adopted the new mortality improvement scale (MP-2017) and recognized a 50 basis point decrease in the discount rate. The Company uses the corridor method to amortize actuarial gains and losses. Gains and losses over 10% of the greater of pension benefit obligation or the market value of assets are amortized over the average future service of plan participants expected to receive benefits. Changes in plan assets and benefit obligations recognized in regulatory assets are as follows: 2018 2017 Net gain (loss) arising during the period $ 252 $ (66 ) Recognized net actuarial loss (406 ) (493 ) Recognized prior service credit 13 13 Total changes in regulatory asset during the year $ (141 ) $ (546 ) Amounts recognized in regulatory assets that have not yet been recognized as components of net periodic benefit cost consist of the following at December 31: 2018 2017 Net loss $ 8,742 $ 8,895 Prior service credit (89 ) (101 ) Regulatory asset $ 8,653 $ 8,794 Components of net periodic benefit cost are as follows: 2018 2017 Service cost $ 1,015 $ 1,080 Interest cost 1,515 1,592 Expected return on plan assets (2,793 ) (2,395 ) Amortization of loss 406 493 Amortization of prior service credit (13 ) (13 ) Rate-regulated adjustment 2,170 1,543 Net periodic benefit cost $ 2,300 $ 2,300 Pension service cost is recorded in operating expenses. All other components of net periodic pension cost are recorded as other pension costs in other income (expenses). The rate-regulated adjustment set forth above is required in order to reflect pension expense for the Company in accordance with the method used in establishing water rates. The Company is permitted by rate order of the PPUC to expense pension costs to the extent of contributions and defer the remaining expense to regulatory assets to be collected in rates at a later date as additional contributions are made. During 2018, the deferral decreased by $2,170. The estimated costs for the defined benefit pension plans relating to the December 31, 2018 balance sheet that will be amortized from regulatory assets into net periodic benefit cost over the next fiscal year are as follows: Net loss $ 508 Net prior service credit (13 ) 495 The Company plans to contribute $2,300 to the plans in 2019. The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid in each of the next five years and the subsequent five years in the aggregate: 2019 2020 2021 2022 2023 2024 2028 $ 1,855 $ 1,865 $ 1,929 $ 2,006 $ 2,177 $ 12,017 The following tables show the projected benefit obligation, the accumulated benefit obligation and the fair value of plan assets as of December 31: 2018 2017 Projected benefit obligation $ 41,511 $ 44,636 Fair value of plan assets 40,624 41,439 2018 2017 Accumulated benefit obligation $ 39,100 $ 41,390 Fair value of plan assets 40,624 41,439 Weighted-average assumptions used to determine benefit obligations at December 31: 2018 2017 Discount rate 4.10% 3.50% Rate of compensation increase 2.50% - 3.00% 2.50% - 3.00% Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31: 2018 2017 Discount rate 3.50% 4.00% Expected long-term return on plan assets 6.75% 6.75% Rate of compensation increase 2.50% - 3.00% 2.50% - 3.00% The selected long-term rate of return on plan assets was primarily based on the asset allocation of each of the plan's assets (approximately 50% to 70% equity securities and 30% to 50% fixed income securities). Analysis of the historic returns of these asset classes and projections of expected future returns were considered in setting the long-term rate of return. The investment objective of the Company's defined benefit pension plans is that of Growth and Income. The weighted-average target asset allocations are 50% to 70% equity securities, 30% to 50% fixed income securities, and 0% to 10% reserves (cash and cash equivalents). Within the equity category, the Company's target allocation is approximately 60-95% large cap, 0-25% mid cap, 0-10% small cap, 0-25% International Developed Nations, and 0-10% International Emerging Nations. Within the fixed income category, its target allocation is approximately 15-55% U.S. Treasuries, 0–22% Federal Agency securities, 0-40% corporate bonds, 15-55% mortgage-backed securities, 0-20% international, and 0-20% high yield bonds. The Company's investment performance objectives over a three to five year period are to exceed the annual rate of inflation as measured by the Consumer Price Index by 3%, and to exceed the annualized total return of specified benchmarks applicable to the funds within the asset categories. Further guidelines within equity securities include: (1) holdings in any one company cannot exceed 5% of the portfolio; (2) a minimum of 20 individual stocks must be included in the domestic stock portfolio; (3) a minimum of 30 individual stocks must be included in the international stock portfolio; (4) equity holdings in any one industry cannot exceed 20-25% of the portfolio; and (5) only U.S.-denominated currency securities are permitted. Further guidelines for fixed income securities include: (1) fixed income holdings in a single issuer are limited to 5% of the portfolio; (2) acceptable investments include money market securities, U.S. Government and its agencies and sponsored entities' securities, mortgage-backed and asset-backed securities, corporate securities and mutual funds offering high yield bond portfolios; (3) purchases must be limited to investment grade or higher; (4) non-U.S. dollar denominated securities are not permissible; and (5) high risk derivatives are prohibited. The fair values of the Company's pension plan assets at December 31, 2018 and 2017 by asset category and fair value hierarchy level are as follows. The majority of the valuations are based on quoted prices on active markets (Level 1), with the remaining valuations based on broker/dealer quotes, active market makers, models, and yield curves (Level 2). Total Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Asset Category 2018 2017 2018 2017 2018 2017 Cash and Money Market Funds (a) $ 1,498 $ 1,968 $ 1,498 $ 1,968 $ – $ – Equity Securities: Common Equity Securities (b) 512 2,606 512 2,606 – – Equity Mutual Funds (c) 23,637 23,416 23,637 23,416 – – Fixed Income Securities: U.S. Treasury Obligations 591 1,106 – – 591 1,106 Corporate and Foreign Bonds (d) 5,315 5,153 – – 5,315 5,153 Fixed Income Mutual Funds (e) 9,071 7,190 9,071 7,190 – – Total Plan Assets $ 40,624 $ 41,439 $ 34,718 $ 35,180 $ 5,906 $ 6,259 (a) The portfolios are designed to keep up to one year of distributions in immediately available funds. The Company was more heavily-weighted in cash as of December 31, 2017 due to the timing of employer contributions. (b) This category includes investments in U.S. common stocks and foreign stocks trading in the U.S. widely distributed among consumer discretionary, consumer staples, healthcare, information technology, financial services, telecommunications, industrials, real estate, and energy. The individual stocks are primarily large cap stocks which track with the S&P 500. (c) This category currently includes a majority of investments in closed-end mutual funds as well as domestic equity mutual funds and international mutual funds which give the portfolio exposure to mid and large cap index funds as well as international diversified index funds. (d) This category currently includes only U.S. corporate bonds and notes widely distributed among consumer discretionary, consumer staples, healthcare, information technology and financial services. (e) This category includes fixed income investments in mutual funds which include government, corporate and mortgage securities of both the U.S. and other countries. The mortgage-backed securities and non-U.S. corporate and sovereign investments add further diversity to the fixed income portion of the portfolio. Defined Contribution Plan The Company has a savings plan pursuant to the provisions of section 401(k) of the Internal Revenue Code. For employees hired before May 1, 2010, this plan provides for elective employee contributions of up to 15% of compensation and Company matching contributions of 100% of the participant's contribution, up to a maximum annual Company contribution of $2.8 for each employee. Employees hired after May 1, 2010 are entitled to an enhanced feature of the plan. This feature provides for elective employee contributions of up to 15% of compensation and Company matching contributions of 100% of the participant's contribution, up to a maximum of 4% of the employee's compensation. In addition, the Company will make an annual contribution of $1.2 to each employee's account whether or not they defer their own compensation. Employees eligible for this enhanced 401(k) plan feature are not eligible for the defined benefit plans. As of December 31, 2018, 43 employees were participating in the enhanced feature of the plan. The Company's contributions to both portions of the plan amounted to $287 in 2018 and $266 in 2017. Deferred Compensation The Company has non-qualified deferred compensation and supplemental retirement agreements with certain members of management. The future commitments under these arrangements are offset by corporate-owned life insurance policies. At December 31, 2018 and 2017, the present value of the future obligations was approximately $3,955 and $3,981, respectively. The insurance policies included in other assets had a total cash value of approximately $3,402 and $3,152 at December 31, 2018 and 2017, respectively. The Company's net expenses under the plans amounted to $32 in 2018 and $252 in 2017. Other The Company has a retiree life insurance program which pays the beneficiary of a retiree $2 upon the retiree’s death. At December 31, 2018 and 2017, the present value of the future obligations was approximately $107 and $120, respectively. There is no trust or insurance covering this future liability, instead the Company will pay these benefits out of its general assets. The Company’s net (income) expenses under the plan amounted to $(10) in 2018 and $19 in 2017. |

Stock-Based Compensation [Abstract] | |
Stock-Based Compensation | 12. Stock-Based Compensation On May 2, 2016, the Company's stockholders approved The York Water Company Long-Term Incentive Plan, or LTIP. The LTIP was adopted to provide the incentive of long-term stock-based awards to officers, directors and key employees. The LTIP provides for the granting of nonqualified stock options, incentive stock options, stock appreciation rights, performance restricted stock grants and units, restricted stock grants and units, and unrestricted stock grants. A maximum of 100,000 shares of common stock may be issued under the LTIP over the ten-year life of the plan. The maximum number of shares of common stock subject to awards that may be granted to any participant in any one calendar year is 2,000. Shares of common stock issued under the LTIP may be treasury shares or authorized but unissued shares. The LTIP is administered by the Compensation Committee of the Board, or the full Board, provided that the full Board administers the LTIP as it relates to awards to non-employee directors of the Company. The Company filed a registration statement with the SEC on May 11, 2016 covering the offering of stock under the LTIP. The LTIP was effective on July 1, 2016. On November 21, 2016, the Board awarded stock to non-employee directors effective November 28, 2016. This stock award vested immediately. On the same date, the Compensation Committee awarded restricted stock to officers and key employees effective November 28, 2016. This restricted stock award vests ratably over three years beginning November 28, 2016. On April 26, 2017, the Board awarded stock to non-employee directors effective May 1, 2017. This stock award vested immediately. On April 26, 2017, the Compensation Committee awarded restricted stock to officers and key employees effective May 1, 2017. This restricted stock award vests ratably over three years beginning May 1, 2017. In addition, the Board of Directors accelerated the vesting period for restricted stock granted in 2016 to two retiring officers from three years to their 2017 retirement dates, both of which have been fully recognized as of December 31, 2017. On May 7, 2018, the Board awarded stock to non-employee directors effective May 7, 2018. This stock award vested immediately. On May 7, 2018, the Compensation Committee awarded restricted stock to officers and key employees effective May 7, 2018. This restricted stock award vests ratably over three years beginning May 7, 2018. On November 20, 2018, the Board accelerated the vesting period for restricted stock granted in 2016, 2017, and 2018 to one retiring officer from three years to that officer’s 2019 retirement date. The restricted stock awards provide the grantee with the rights of a shareholder, including the right to receive dividends and to vote such shares, but not the right to sell or otherwise transfer the shares during the restriction period. As a result, the awards are included in common shares outstanding on the balance sheet. Restricted stock awards result in compensation expense valued at the fair market value of the stock on the date of the grant and are amortized ratably over the restriction period. The following table summarizes the stock grant amounts and activity for the years ended December 31, 2017 and 2018. Number of Shares Grant Date Weighted Average Fair Value Nonvested at beginning of the year 2017 660 $37.20 Granted 1,505 $38.00 Vested (1,038) $37.75 Forfeited - - Nonvested at end of the year 2017 1,127 $37.76 Granted 3,743 $32.70 Vested (1,790) $33.90 Forfeited - - Nonvested at end of the year 2018 3,080 $33.85 For the years ended December 31, 2018 and 2017, the statement of income includes $80 and $46 of stock based compensation and related recognized tax benefits of $23 and $18, respectively. The total fair value of the shares vested in the years ended December 31, 2018 and 2017 was $61 and $39, respectively. Total stock based compensation related to nonvested awards not yet recognized is $104 at December 31, 2018 which will be recognized over the remaining three year vesting period. |

Income Taxes | 14. Income Taxes The provisions for income taxes consist of: 2018 2017 Federal current $ 1,715 $ 1,213 State current 718 846 Federal deferred 216 2,514 State deferred (119 ) 9 Federal investment tax credit, net of current utilization (39 ) (39 ) Total income taxes $ 2,491 $ 4,543 A reconciliation of the statutory Federal tax provision to the total provision follows: 2018 2017 Statutory Federal tax provision $ 3,332 $ 5,956 State income taxes, net of Federal benefit 471 563 IRS TPR ongoing deduction (1,307 ) (1,796 ) Tax-exempt interest (22 ) (33 ) Amortization of investment tax credit (39 ) (39 ) Cash value of life insurance (13 ) (9 ) Domestic production deduction – (177 ) Change in enacted federal tax rate – 134 Other, net 69 (56 ) Total income taxes $ 2,491 $ 4,543 The Company filed for a change in accounting method under the IRS TPR effective in 2014. Under the change in accounting method, the Company is permitted to deduct the costs of certain asset improvements that were previously being capitalized and depreciated for tax purposes as an expense on its income tax return. The Company was permitted to make this deduction for prior years (the “catch-up deduction”) and for each year going forward (the “ongoing deduction”). As a result of the catch-up deduction, income tax benefits of $3,887 were deferred as a regulatory liability. The Company received approval from the PPUC in its most recent rate order to amortize the catch-up deduction recorded as a regulatory liability, over 15 years beginning March 1, 2019. As a result of the ongoing deduction, the net income tax benefits of $1,307 and $1,796 for the years ended December 31, 2018 and 2017, respectively, reduced income tax expense and flowed-through to net income. The ongoing deduction results in a reduction in the effective income tax rate, a net reduction in income tax expense, and a reduction in the amount of income taxes currently payable. Both the ongoing and catch-up deductions result in increases to deferred tax liabilities and regulatory assets representing the appropriate book and tax basis difference on capital additions. The 2017 Tax Act, among other things, reduces the federal statutory corporate tax rate for tax years beginning in 2018 from 34% to 21%, eliminates certain deductions, and eliminates bonus depreciation on qualified water and wastewater property. This resulted in the remeasurement of the federal portion of the Company’s deferred taxes as of December 31, 2017 to the 21% rate. The effect was recognized in income for the year ended December 31, 2017 for all deferred tax assets and liabilities except accelerated depreciation. Under normalization rules applicable to public utility property included in the 2017 Tax Act, the excess accumulated deferred income taxes on accelerated depreciation is recorded as a regulatory liability. The regulatory liability is a temporary difference so a deferred tax asset is recorded including the gross-up of revenue necessary to return, in rates, the effect of the temporary difference. The tax effects of temporary differences between book and tax balances that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31, 2018 and 2017 are summarized in the following table: 2018 2017 Deferred tax assets: Reserve for doubtful accounts $ 88 $ 88 Compensated absences 147 147 Deferred compensation 1,143 1,150 Excess accumulated deferred income taxes on accelerated depreciation 4,098 4,145 Deferred taxes associated with the gross-up of revenues necessary to return, in rates, the effect of temporary differences 2,077 1,736 Customers' advances for construction and contributions in aid of construction 577 - Revenue reduction for tax rate change 333 - Pensions 256 924 Other costs deducted for book, not for tax 40 42 Total deferred tax assets 8,759 8,232 Deferred tax liabilities: Accelerated depreciation 28,479 27,785 Basis differences from IRS TPR 9,367 7,579 Investment tax credit 411 439 Deferred taxes associated with the gross-up of revenues necessary to return, in rates, the effect of temporary differences 6,124 5,291 Tax effect of pension regulatory asset 887 1,555 Other costs deducted for tax, not for book 453 337 Total deferred tax liabilities 45,721 42,986 Net deferred tax liability $ 36,962 $ 34,754 In accordance with accounting standards, the net deferred tax liability is classified as a noncurrent deferred income tax liability on the balance sheets. No valuation allowance was required for deferred tax assets as of December 31, 2018 and 2017. In assessing the value of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Based upon expected future taxable income and the current regulatory environment, management believes it is more likely than not that the Company will realize the benefits of these deductible differences. The Company determined that there were no uncertain tax positions meeting the recognition and measurement test of the accounting standards recorded in the years that remain open for review by taxing authorities, which are 2015 through 2017 for both federal and state income tax returns. The Company has not yet filed tax returns for 2018. The Company believes that it has fully complied with any changes pursuant to the 2017 Tax Act and has not taken any new positions in its 2018 income tax provision, apart from compliance with the 2017 Tax Act. The Company's policy is to recognize interest and penalties related to income tax matters in other expenses. The Company paid interest and penalties of $1 and $0 for the years ended December 31, 2018 and 2017, respectively. |

Utility Plant and Depreciation | Utility Plant and Depreciation The cost of additions includes contracted cost, direct labor and fringe benefits, materials, overhead and, for certain utility plant, allowance for funds used during construction. In accordance with regulatory accounting requirements, water and wastewater systems acquired are recorded at estimated original cost of utility plant when first devoted to utility service and the applicable depreciation is recorded to accumulated depreciation. The difference between the estimated original cost less applicable accumulated depreciation, and the purchase price and acquisition costs is recorded as an acquisition adjustment within utility plant as permitted by the PPUC. At December 31, 2018 and 2017, utility plant includes a net credit acquisition adjustment of $3,108 and $3,234, respectively. For those amounts approved by the PPUC, the net acquisition adjustment is being amortized over the remaining life of the respective assets. Certain amounts are still awaiting approval from the PPUC before amortization will commence. Amortization amounted to $58 in each of the two years in the period ended December 31, 2018. Upon normal retirement of depreciable property, the estimated or actual cost of the asset is credited to the utility plant account, and such amounts, together with the cost of removal less salvage value, are charged to the reserve for depreciation. To the extent the Company recovers cost of removal or other retirement costs through rates after the retirement costs are incurred, a regulatory asset is reported. Gains or losses from abnormal retirements are reflected in income currently. The straight-line remaining life method is used to compute depreciation on utility plant cost, exclusive of land and land rights. Annual provisions for depreciation of transportation and mechanical equipment included in utility plant are computed on a straight-line basis over the estimated service lives. Such provisions are charged to clearing accounts and apportioned therefrom to operating expenses and other accounts in accordance with the Uniform System of Accounts as prescribed by the PPUC. The Company charges to maintenance expense the cost of repairs and replacements and renewals of minor items of property. Maintenance of transportation equipment is charged to clearing accounts and apportioned therefrom in a manner similar to depreciation. The cost of replacements, renewals and betterments of units of property is capitalized to the utility plant accounts. The following remaining lives are used for financial reporting purposes: December 31, Approximate range Utility Plant Asset Category 2018 2017 of remaining lives Mains and accessories $ 190,679 $ 182,927 11 – 86 years Services, meters and hydrants 74,178 71,183 18 – 52 years Operations structures, reservoirs and water tanks 61,868 53,610 9 – 59 years Pumping and treatment equipment 32,575 29,814 8 – 31 years Office, transportation and operating equipment 13,531 12,787 3 – 24 years Land and other non-depreciable assets 3,202 3,196 - Utility plant in service 376,033 353,517 Construction work in progress 4,751 12,250 - Total Utility Plant $ 380,784 $ 365,767 The effective rate of depreciation was 2.21% in 2018 and 2.26% in 2017 on average utility plant, net of customers' advances and contributions. Larger depreciation provisions resulting from allowable accelerated methods are deducted for tax purposes. |
Cash and Cash Equivalents | Cash and Cash Equivalents For the purposes of the statements of cash flows, the Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents except for those instruments earmarked to fund construction expenditures or repay long-term debt. The Company periodically maintains cash balances in major financial institutions in excess of the federally insured limit by the Federal Deposit Insurance Corporation (FDIC). The Company has not experienced any losses and believes it is not exposed to any significant credit risk on cash and cash equivalents. |
Accounts Receivable | Accounts Receivable Accounts receivable are stated at outstanding balances, less a reserve for doubtful accounts. The reserve for doubtful accounts is established through provisions charged against income. Accounts deemed to be uncollectible are charged against the reserve and subsequent recoveries, if any, are credited to the reserve. The reserve for doubtful accounts is maintained at a level considered adequate to provide for losses that can be reasonably anticipated. Management's periodic evaluation of the adequacy of the reserve is based on past experience, agings of the receivables, adverse situations that may affect a customer's ability to pay, current economic conditions, and other relevant factors. This evaluation is inherently subjective. Unpaid balances remaining after the stated payment terms are considered past due. |
Materials and Supplies Inventories | Materials and Supplies Inventories Materials and supplies inventories are stated at cost. Costs are determined using the average cost method. |
Notes Receivable | Note Receivable Note receivable is recorded at cost and represent amounts due from a municipality for construction of water mains in their municipality. Management, considering current information and events regarding the borrowers' ability to repay their obligations, considers a note to be impaired when it is probable that the Company will be unable to collect all amounts due according to the contractual terms of the note agreement. When a note is considered to be impaired, the carrying value of the note is written down. The amount of the impairment is measured based on the present value of expected future cash flows discounted at the note's effective interest rate. |
Regulatory Assets and Liabilities | Regulatory Assets and Liabilities The Company is subject to the provisions of generally accepted accounting principles regarding rate-regulated entities. The accounting standards provide for the recognition of regulatory assets and liabilities as allowed by regulators for costs or credits that are reflected in current customer rates or are considered probable of being included in future rates. The regulatory assets or liabilities are then relieved as the cost or credit is reflected in rates. Regulatory assets represent costs that are expected to be fully recovered from customers in future rates while regulatory liabilities represent amounts that are expected to be refunded to customers in future rates. These deferred costs have been excluded from the Company’s rate base and, therefore, no return is being earned on the unamortized balances. Regulatory assets and liabilities are comprised of the following: December 31, Remaining Recovery 2018 2017 Periods Assets Income taxes $ 21,432 $ 18,564 Various Postretirement benefits 3,071 5,382 5 – 10 years Unrealized swap losses 1,799 2,172 1 – 11 years Utility plant retirement costs 4,841 3,994 5 years Customer-owned lead service line replacements 304 191 4 years Income taxes on customers' advances for construction and contributions in aid of construction 577 - Various Service life study expenses 18 23 4 years Rate case filing expenses 311 5 3 years $ 32,353 $ 30,331 Liabilities Excess accumulated deferred income taxes on accelerated depreciation $ 14,184 $ 14,348 Various Income taxes 6,979 6,260 Various IRS TPR catch-up deduction 3,887 3,887 15 years Revenue reduction for tax rate change 1,764 - 2 years $ 26,814 $ 24,495 The regulatory asset for income taxes includes (a) deferred state income taxes related primarily to differences between book and tax depreciation expense, (b) deferred income taxes related to the differences that arise between specific asset improvement costs capitalized for book purposes and deducted as a repair expense for tax purposes, and (c) deferred income taxes associated with the gross-up of revenues related to the differences. These assets are recognized for ratemaking purposes on a cash or flow-through basis and will be recovered in rates as they reverse. Postretirement benefits include the difference between contributions and deferred pension expense and the underfunded status of the pension plans. The underfunded status represents the difference between the projected benefit obligation and the fair market value of the assets. This asset is expected to be recovered in future years as additional contributions are made or markets continue to generate positive returns. The recovery period is dependent on contributions made to the plans, plan asset performance and the discount rate used to value the obligations. The period is estimated at between 5 and 10 years. The Company uses regulatory accounting treatment to defer the mark-to-market unrealized gains and losses on its interest rate swap to reflect that the gain or loss is included in the ratemaking formula when the transaction actually settles. The value of the swap as of the balance sheet date is recorded as part of other deferred credits. Realized gains or losses on the swap will be recorded as interest expense in the statement of income over its remaining life of 11 years. Utility plant retirement costs represents costs already incurred for the removal of assets, which are expected to be recovered over a five-year period in rates, through depreciation expense. The Company was granted approval by the PPUC to modify its tariff to replace lead customer-owned service lines that are discovered when the Company replaces its lead service lines over the remaining three years, and to include the cost of the annual replacement of up to 400 lead customer-owned service lines whenever they are discovered, regardless of the material used for the company-owned service line over nine years. The tariff modification allows the Company to replace customer-owned service lines at its own initial cost and record the costs as a regulatory asset to be recovered in future base rates to customers. The recovery period was established in the most recent rate order at four years. Service life study expenses are deferred and amortized over their remaining life of four years. Rate case filing expenses are deferred and amortized over their life of three years. Pursuant to the Tax Cuts and Jobs Act of 2017, or 2017 Tax Act, customers’ advances for construction and contributions in aid of construction are considered taxable income. The Company’s tariff allows the Company to record these income taxes for inclusion in rate base. This asset is recognized for ratemaking purposes on a cash or flow-through basis and will be recovered in rates as it reverses. Under normalization rules applicable to public utility property included in the 2017 Tax Act, the excess accumulated deferred income taxes on accelerated depreciation from lowering of the enacted federal statutory corporate tax rate is recorded as a regulatory liability. The benefit will be given back to customers in rates over the remaining regulatory life of the property. The regulatory liability for income taxes includes deferred taxes related to excess accumulated deferred income taxes on accelerated depreciation, other postretirement benefits, customers’ advances for construction and contributions in aid of construction, and bad debts, as well as deferred investment tax credits. These liabilities will be given back to customers in rates, as tax deductions occur over the next 1 to 50 years. The regulatory liability for the Internal Revenue Service, or IRS, tangible property regulations, or TPR, catch-up deduction represents the tax benefits realized on the Company’s 2014 income tax return for qualifying capital expenditures made prior to 2014. The Company received approval from the PPUC in its most recent rate order to amortize the catch-up deduction over 15 years beginning March 1, 2019. Pursuant to a rate order approved by the PPUC, the Company has agreed to return the 2018 income tax savings pursuant to the 2017 Tax Act, the associated tax gross-up, and the excess accumulated deferred income taxes on accelerated depreciation to customers as a reconcilable negative surcharge on bills. The liability will be given back to customers as a negative surcharge on bills over one year beginning March 1, 2019. |
Other Assets | Other Assets Other assets consist mainly of the cash value of life insurance policies held as an investment by the Company for reimbursement of costs and benefits associated with its supplemental retirement and deferred compensation programs. |
Deferred Debt Expense | Deferred Debt Expense Deferred debt expense is amortized on a straight-line basis over the term of the related debt and is presented on the balance sheet as a direct reduction from long-term debt. |
Customers' Advances for Construction | Customers' Advances for Construction Customer advances are cash payments from developers, municipalities, customers or builders for construction of utility plant, and are refundable upon completion of construction, as operating revenues are earned. If the Company loans funds for construction to the customer, the refund amount is credited to the note receivable rather than paid out in cash. After all refunds to which the customer is entitled are made, any remaining balance is transferred to contributions in aid of construction. |
Contributions in Aid of Construction | Contributions in Aid of Construction Contributions in Aid of Construction is composed of (i) direct, non-refundable contributions from developers, customers or builders for construction of water infrastructure and (ii) customer advances that have become non-refundable. Contributions in aid of construction are deducted from the Company’s rate base, and therefore, no return is earned on property financed with contributions. The PPUC requires that contributions received remain on the Company’s balance sheets indefinitely as a long-term liability. |
Interest Rate Swap Agreement | Interest Rate Swap Agreement The Company is exposed to certain risks relating to its ongoing business operations. The primary risk managed by using derivative instruments is interest rate risk. The Company utilizes an interest rate swap agreement to convert its variable-rate debt to a fixed rate. Interest rate swaps are contracts in which a series of interest rate cash flows are exchanged over a prescribed period. The notional amount on which the interest payments are based is not exchanged. The Company has designated the interest rate swap agreement as a cash flow hedge, classified as a financial derivative used for non-trading activities. The accounting standards regarding accounting for derivatives and hedging activities require companies to recognize all derivative instruments as either assets or liabilities at fair value on the balance sheets. In accordance with the standards, the interest rate swap is recorded on the balance sheets in other deferred credits at fair value. The Company uses regulatory accounting treatment rather than hedge accounting to defer the unrealized gains and losses on its interest rate swap. Instead of the effective portion being recorded as other comprehensive income and the ineffective portion being recognized in earnings, the entire unrealized swap value is recorded as a regulatory asset. Based on current ratemaking treatment, the Company expects the gains and losses to be recognized in rates and in interest expense as the swap settlements occur. Swap settlements are recorded in the income statement with the hedged item as interest expense. Swap settlements resulted in the reclassification from regulatory assets to interest expense of $236 in 2018 and $301 in 2017. The overall swap result was a (gain) loss of $(137) in 2018 and $209 in 2017. During the twelve months ending December 31, 2019, the Company expects to reclassify $199 (before tax) from regulatory assets to interest expense. The interest rate swap will expire on October 1, 2029. |
Stock-Based Compensation | Stock-Based Compensation The Company records compensation expense in the financial statements for stock-based awards based on the grant date fair value of those awards. Stock-based compensation expense is recognized over the requisite service periods of the awards on a straight-line basis, which is generally commensurate with the vesting term. Forfeitures are recognized as they occur. |
Income Taxes | Income Taxes Certain income and expense items are accounted for in different time periods for financial reporting than for income tax reporting purposes. Deferred income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. To the extent such income taxes increase or decrease future rates, an offsetting regulatory asset or liability has been recorded. Investment tax credits have been deferred and are being amortized to income over the average estimated service lives of the related assets. As of December 31, 2018 and 2017, deferred investment tax credits amounted to $578 and $618, respectively. The Company filed for a change in accounting method under the IRS TPR effective in 2014. Under the change in accounting method, the Company is permitted to deduct the costs of certain asset improvements that were previously being capitalized and depreciated for tax purposes as an expense on its income tax return. The Company is permitted to make this deduction for prior years (the “catch-up deduction”) and each year going forward, beginning with 2014 (the “ongoing deduction”). The ongoing deduction results in a reduction in the effective income tax rate, a net reduction in income tax expense, and a reduction in the amount of income taxes currently payable. The catch-up deduction resulted in a decrease in current income taxes payable and an increase to regulatory liabilities. The Company received approval from the PPUC in its most recent rate order to amortize the catch-up deduction, recorded as a regulatory liability, over 15 years beginning March 1, 2019. Both the ongoing and catch-up deductions resulted in increases to deferred tax liabilities and regulatory assets representing the appropriate book and tax basis difference on capital additions. The 2017 Tax Act, among other things, reduces the federal statutory corporate tax rate for tax years beginning in 2018 from 34% to 21%, eliminates certain deductions, and eliminates bonus depreciation on qualified water and wastewater property. This resulted in the remeasurement of the federal portion of the Company’s deferred taxes as of December 31, 2017 to the 21% rate. The effect was recognized in income for the year ended December 31, 2017 for all deferred tax assets and liabilities except accelerated depreciation. Under normalization rules applicable to public utility property included in the 2017 Tax Act, the excess accumulated deferred income taxes on accelerated depreciation is recorded as a regulatory liability. The regulatory liability is a temporary difference so a deferred tax asset is recorded including the gross-up of revenue necessary to return, in rates, the effect of the temporary difference. |
Allowance for Funds Used During Construction | Allowance for Funds Used During Construction Allowance for funds used during construction (AFUDC) represents the estimated cost of funds used for construction purposes during the period of construction. These costs are reflected as non-cash income during the construction period and as an addition to the cost of plant constructed. AFUDC includes the net cost of borrowed funds and a rate of return on other funds. The PPUC approved rate of 10.04% was applied for 2018 and 2017. AFUDC is recovered through water and wastewater rates as utility plant is depreciated. |
Use of Estimates in the Preparation of Financial Statements | Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
Reclassifications | Reclassifications Certain 2017 amounts have been reclassified to conform to the 2018 presentation. Such reclassifications had no effect on the balance sheets, net income, the statements of common stockholders’ equity, or the statements of cash flows. |
Impact of Recent Accounting Pronouncements | Impact of Recent Accounting Pronouncements In May 2017, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost . This ASU requires employers to report the service cost component in the same line item as other compensation costs arising from services rendered by employees during the reporting period. The other components of net benefit costs will be presented in the income statement separately from the service cost and outside of a subtotal of income from operations. In addition, only the service cost component may be eligible for capitalization where applicable. The ASU is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years, with early adoption available. The Company adopted the standard on January 1, 2018. The adoption of this standard resulted in the reclassification on the statements of income of the components of net periodic pension cost other than service cost from operating expenses to other pension costs in other income (expenses) of $1,285 and $1,220 for the years ended , 2018 and 2017, respectively. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 320): Classification of Certain Cash Receipts and Cash Payments. The Company adopted the standard on January 1, 2018. The adoption did not have an impact on its financial position, results of operations and cash flows. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers.

Revenue [Abstract] | |
Revenue | Utility Service The Company provides utility service as a distinct and single performance obligation to each of its water and wastewater customers. The transaction price is detailed in the tariff pursuant to an order by the PPUC and made publicly available. There is no variable consideration and no free service, special rates, or subnormal charges to any customer. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied over time through the continuous provision of utility service through a stand-ready obligation to perform and the transfer of water or the collection of wastewater through a series of distinct transactions that are identical in nature and have the same pattern of transfer to the customer. The Company uses an output method to recognize the utility service revenue over time. The stand-ready obligation is recognized through the passage of time in the form of a fixed charge and the transfer of water or the collection of wastewater is recognized at a per unit rate based on the actual or estimated flow through the meter. Each customer is invoiced every month and the invoice is due within twenty days. The utility service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. A contract asset for unbilled revenue is recognized for the passage of time and the actual or estimated usage from the latest meter reading to the end of the accounting period. The methodology is standardized and consistently applied to reduce bias and the need for judgment. Billing and Revenue Collection Service The Company provides billing and revenue collection service as distinct performance obligations to four municipalities within the service territory of the Company. The municipalities provide wastewater service to their residents and the Company acts as the billing and revenue collection agent for the municipalities. The transaction price is a fixed amount per bill prepared as established in the contract. There is no variable consideration. Due to the fact that both the billing performance obligation and the revenue collection performance obligation are materially complete by the end of the reporting period, the Company does not allocate the transaction price between the two performance obligations. The performance obligations are satisfied at a point in time when the bills are sent as the municipalities receive all the benefits and bears all of the risk of non-collection at that time. Each municipality is invoiced when the bills are complete and the invoice is due within thirty days. The billing and revenue collection service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. Collection Service The Company provides collection service as a distinct and single performance obligation to several municipalities within the service territory of the Company. The municipalities provide wastewater service to their residents. If those residents are delinquent in paying for their wastewater service, the municipalities request that the Company post for and shut off the supply of water to the premises of those residents. When the resident is no longer delinquent, the Company will restore water service to the premises. The transaction price for each posting, each shut off, and each restoration is a fixed amount as established in the contract. There is no variable consideration. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied at a point in time when the posting, shut off, or restoration is completed as the municipalities receive all the benefits in the form of payment or no longer providing wastewater service. Each municipality is invoiced periodically for the posting, shut offs, and restorations that have been completed since the last billing and the invoice is due within thirty days. The collection service has no returns or warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no performance obligations remain unsatisfied as of the end of the reporting period. A contract asset for unbilled revenue is recognized for postings, shut offs, and restorations that have been completed from the last billing to the end of the accounting period. Service Line Protection Plan The Company provides service line protection as a distinct and single performance obligation to current water customers that choose to participate. The transaction price is detailed in the plan’s terms and conditions and made publicly available. There is no variable consideration. Due to the fact that the contract includes a single performance obligation, no judgment is required to allocate the transaction price. The performance obligation is satisfied over time through the continuous provision of service line protection through a stand-ready obligation to perform. The Company uses an output method to recognize the service line protection revenue over time. The stand-ready obligation is recognized through the passage of time. A customer has a choice to prepay for an entire year or to pay in advance each month. The service line protection plan has no returns or extended warranties associated with it. No revenue is recognized from performance obligations satisfied in prior periods and no material performance obligations remain unsatisfied as of the end of the reporting period. |
