| Basis Of Presentation | Note 1 – Basis of Presentation The accompanying consolidated balance sheets and statements of capitalization of Aqua America, Inc. and subsidiaries (the “Company”) at September 30, 2017, the consolidated statements of net income and comprehensive income for the three and nine months ended September 30, 2017 and 2016 the consolidated statements of cash flow for the nine months ended September 30, 2017 and 2016, and the consolidated statement of equity for the nine months ended September 30, 2017 are unaudited, but reflect all adjustments, consisting of only normal recurring accruals, which are, in the opinion of management, necessary to present a fair statement of its consolidated financial position, consolidated changes in equity, consolidated results of operations, and consolidated cash flow for the periods presented. Because they cover interim periods, the statements and related notes to the financial statements do not include all disclosures and notes normally provided in annual financial statements and, therefore, should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. The results of operations for interim periods may not be indicative of the results that may be expected for the entire year. The December 31, 2016 consolidated balance sheet data presented herein was derived from the Company’s December 31, 2016 audited consolidated financial statements, but does not include all disclosures and notes normally provided in annual financial statements. Certain prior period amounts have been reclassified to conform to the current period presentation in the consolidated statements of cash flows:
The preparation of financial statements often requires the selection of specific accounting methods and policies. Further, significant estimates and judgments may be required in selecting and applying those methods and policies in the recognition of the assets and liabilities in its consolidated balance sheets, the revenues and expenses in its consolidated statements of net income, and the information that is contained in its summary of significant accounting policies and notes to consolidated financial statements. Making these estimates and judgments requires the analysis of information concerning events that may not yet be complete and of facts and circumstances that may change over time. Accordingly, actual amounts or future results can differ materially from those estimates that the Company includes currently in its consolidated financial statements, summary of significant accounting policies, and notes. There have been no changes to the summary of significant accounting policies previously identified in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

| Goodwill | Note 2 – Goodwill The following table summarizes the changes in the Company’s goodwill, by business segment:
The reclassification of goodwill to utility plant acquisition adjustment results from a mechanism approved by the applicable utility commission. The mechanism provides for the transfer over time, and the recovery through customer rates, of goodwill associated with some acquisitions upon achieving specific objectives. Goodwill is not amortized but is tested for impairment annually, or more often, if circumstances indicate a possible impairment may exist, to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. When testing goodwill for impairment, the Company may assess qualitative factors, including macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, and entity specific events. Alternatively, the Company may bypass this qualitative assessment for some of its reporting units and perform a quantitative goodwill impairment test by determining the fair value of a reporting unit based on a discounted cash flow analysis. The Company tested the goodwill attributable to each of its reporting units for impairment as of July 31, 2017, in conjunction with the timing of its annual strategic business plan, and concluded that the estimated fair value of each reporting unit, which has goodwill recorded, exceeded the reporting unit’s carrying amount, indicating that none of the Company’s goodwill was impaired.

| Acquisitions [Abstract] | |
| Acquisitions | Note 3 – Acquisitions During the first nine months of 2017, the Company completed four acquisitions of water and wastewater utility systems in various states adding 1,003 customers. The total purchase price of these utility systems consisted of $5,860 in cash, which resulted in $72 of goodwill being recorded. The pro forma effect of the businesses acquired is not material either individually or collectively to the Company’s results of operations. As part of the Company’s growth-through-acquisition strategy, the Company has entered into purchase agreements to acquire the water or wastewater utility system assets of five municipalities for a total combined purchase price in cash of $145,700. The purchase price for these pending acquisitions is subject to certain adjustments at closing, and is subject to regulatory approvals. Closing for these acquisitions are expected to occur by mid-year 2018, which is subject to the timing of the regulatory approval process. These acquisitions will add approximately 14,900 customers in two of the states that the Company operates in. Pursuant to its strategy to grow through acquisitions, in January 2016, the Company acquired Superior Water Company, Inc., which provides public water service to approximately 3,900 customers in portions of Berks, Chester, and Montgomery counties in Pennsylvania. The total purchase price for the utility system was $16,750, which consisted of the issuance of 439,943 shares of the Company’s common stock and $3,905 in cash. The purchase price allocation for this acquisition consisted primarily of acquired property, plant and equipment of $25,167, contributions in aid of construction of $16,565, and goodwill of $8,622. Additionally, during 2016, the Company completed eighteen acquisitions of water and wastewater utility systems in various states adding 2,469 customers. The total purchase price of these utility systems consisted of $5,518 in cash, which resulted in $1,756 of goodwill being recorded. The pro forma effect of the businesses acquired is not material either individually or collectively to the Company’s results of operations.

Fair Value Of Financial Instruments |

| Fair Value Of Financial Instruments | Note 6 – Fair Value of Financial Instruments
The Company follows the FASB’s accounting guidance for fair value measurements and disclosures, which defines fair value and establishes a framework for using fair value to measure assets and liabilities. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are as follows:
The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. There have been no changes in the valuation techniques used to measure fair value, or asset or liability transfers between the levels of the fair value hierarchy for the quarter ended September 30, 2017. Financial instruments are recorded at carrying value in the financial statements and approximate fair value as of the dates presented. The fair value of these instruments is disclosed below in accordance with current accounting guidance related to financial instruments. The fair value of loans payable is determined based on its carrying amount and utilizing Level 1 methods and assumptions. As of September 30, 2017 and December 31, 2016, the carrying amount of the Company’s loans payable was $20,990 and $6,535, respectively, which equates to their estimated fair value. The Company’s deferred compensation plan liability is determined by the fair value of mutual funds, which are based on quoted market prices from active markets utilizing Level 1 methods and assumptions. As of September 30, 2017 and December 31, 2016, the carrying amount of these securities was $18,145 and $17,072, which equates to their fair value, and is reported in the consolidated balance sheet in deferred charges and other assets. The fair value of cash and cash equivalents, which is comprised of a money market fund, is determined based on the net asset value per unit utilizing Level 2 methods and assumptions. As of September 30, 2017 and December 31, 2016, the carrying amounts of the Company's cash and cash equivalents was $4,139 and $3,763, respectively, which equates to their fair value. The carrying amounts and estimated fair values of the Company’s long-term debt is as follows:
The fair value of long-term debt has been determined by discounting the future cash flows using current market interest rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions. The Company’s customers’ advances for construction have a carrying value of $107,715 as of September 30, 2017, and $91,843 as of December 31, 2016. Their relative fair values cannot be accurately estimated because future refund payments depend on several variables, including new customer connections, customer consumption levels, and future rate increases. Portions of these non-interest bearing instruments are payable annually through 2027 and amounts not paid by the respective contract expiration dates become non-refundable. The fair value of these amounts would, however, be less than their carrying value due to the non-interest bearing feature.

| Net Income Per Common Share | Note 7 – Net Income per Common Share
Basic net income per common share is based on the weighted average number of common shares outstanding. Diluted net income per common share is based on the weighted average number of common shares outstanding and potentially dilutive shares. The dilutive effect of employee stock-based compensation is included in the computation of diluted net income per common 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 treasury stock method assumes that the proceeds from stock-based compensation are used to purchase the Company’s common stock at the average market price during the period. The following table summarizes the shares, in thousands, used in computing basic and diluted net income per common share:
For the three and nine months ended September 30, 2017 and 2016, all of the Company’s employee stock options were included in the calculations of diluted net income per share as the calculated cost to exercise the stock options was less than the average market price of the Company’s common stock during these periods.

| Stock-Based Compensation | Note 8 – Stock-based Compensation
Under the Company’s 2009 Omnibus Equity Compensation Plan, as amended as of February 27, 2014 (the “2009 Plan”), as approved by the Company’s shareholders to replace the 2004 Equity Compensation Plan (the “2004 Plan”), stock options, stock units, stock awards, stock appreciation rights, dividend equivalents, and other stock-based awards may be granted to employees, non-employee directors, and consultants and advisors. The 2009 Plan authorizes 6,250,000 shares for issuance under the plan. A maximum of 3,125,000 shares under the 2009 Plan may be issued pursuant to stock awards, stock units and other stock-based awards, subject to adjustment as provided in the 2009 Plan. During any calendar year, no individual may be granted (i) stock options and stock appreciation rights under the 2009 Plan for more than 500,000 shares of Company stock in the aggregate or (ii) stock awards, stock units or other stock-based awards under the 2009 Plan for more than 500,000 shares of Company stock in the aggregate, subject to adjustment as provided in the 2009 Plan. Awards to employees and consultants under the 2009 Plan are made by a committee of the Board of Directors of the Company, except that with respect to awards to the Chief Executive Officer, the committee recommends those awards for approval by the non-employee directors of the Board of Directors. In the case of awards to non-employee directors, the Board of Directors makes such awards. At September 30, 2017, 3,741,526 shares were still available for issuance under the 2009 Plan. No further grants may be made under the 2004 Plan.
Performance Share Units – A performance share unit (“PSU”) represents the right to receive a share of the Company’s common stock if specified performance goals are met over the three-year performance period specified in the grant, subject to exceptions through the respective vesting period, generally three years. Each grantee is granted a target award of PSUs, and may earn between 0% and 200% of the target amount depending on the Company’s performance against the performance goals. The following table provides compensation costs for stock-based compensation related to PSUs:
The following table summarizes the PSU transactions for the nine months ended September 30, 2017:
A portion of the fair value of PSUs was estimated at the grant date based on the probability of satisfying the market-based conditions using the Monte Carlo valuation method, which assesses probabilities of various outcomes of market conditions. The other portion of the fair value of the PSUs is based on the fair market value of the Company’s stock at the grant date, regardless of whether the market-based condition is satisfied. The per unit weighted-average fair value at the date of grant for PSUs granted during the nine months ended September 30, 2017 and 2016 was $30.79 and $28.89, respectively. The fair value of each PSU grant is amortized monthly into compensation expense on a straight-line basis over their respective vesting periods, generally 36 months. The accrual of compensation costs is based on the Company’s estimate of the final expected value of the award, and is adjusted as required for the portion based on the performance-based condition. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the PSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the PSUs. The recording of compensation expense for PSUs has no impact on net cash flows. Restricted Stock Units – A restricted stock unit (“RSU”) represents the right to receive a share of the Company’s common stock. RSUs are eligible to be earned at the end of a specified restricted period, generally three years, beginning on the date of grant. The Company assumes that forfeitures will be minimal, and recognizes forfeitures as they occur, which results in a reduction in compensation expense. As the payout of the RSUs includes dividend equivalents, no separate dividend yield assumption is required in calculating the fair value of the RSUs. The following table provides the compensation cost and income tax benefit for stock-based compensation related to RSUs:
The following table summarizes the RSU transactions for the nine months ended September 30, 2017:
The per unit weighted-average fair value at the date of grant for RSUs granted during the nine months ended September 30, 2017 and 2016 was $30.37 and $32.09, respectively. Stock Options – A stock option represents the option to purchase a number of shares of common stock of the Company as specified in the stock option grant agreement at the exercise price per share as determined by the closing market price of our common stock on the grant date. Stock options are exercisable in installments of 33% annually, starting one year from the grant date and expire 10 years from the grant date. The fair value of each stock option is amortized into compensation expense using the graded-vesting method, which results in the recognition of compensation costs over the requisite service period for each separately vesting tranche of the stock options as though the stock options were, in substance, multiple stock option grants. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock options:
The fair value of options was estimated at the grant date using the Black-Scholes option-pricing model. The following assumptions were used in the application of this valuation model:
Historical information was the principal basis for the selection of the expected term and dividend yield. The expected volatility is based on a weighted-average combination of historical and implied volatilities over a time period that approximates the expected term of the option. The risk-free interest rate was selected based upon the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. For the nine months ended September 30, 2016, there were no compensation costs for stock-based compensation related to stock options, as the previous stock option grant that occurred in 2010 became fully amortized in 2013. Additionally, there were no stock options granted during the nine months ended September 30, 2016. The following table summarizes stock option transactions for the nine months ended September 30, 2017:
Stock Awards – Stock awards represent the issuance of the Company’s common stock, without restriction. The issuance of stock awards results in compensation expense which is equal to the fair market value of the stock on the grant date, and is expensed immediately upon grant. The following table provides the compensation cost and income tax benefit for stock-based compensation related to stock awards:
The following table summarizes stock award transactions for the nine months ended September 30, 2017:
