- Definition Carrying amount as of the balance sheet date of capitalized costs of regulated entities that are expected to be recovered through revenue sources within one year or the normal operating cycle, if longer. Such costs are capitalized if they meet both of the following criteria: a. It is probable that future revenue in an amount at least equal to the capitalized cost will result from inclusion of that cost in allowable costs for rate-making purposes. b. Based on available evidence, the future revenue will be provided to permit recovery of the previously incurred cost rather than to provide for expected levels of similar future costs. If the revenue will be provided through an automatic rate-adjustment clause, this criterion requires that the regulator's intent clearly be to permit recovery of the previously incurred cost.

Summary of Significant Accounting Policies: |

| Accounting Policies [Abstract] | |
| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies: Nature of Operations: American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”) and American States Utility Services, Inc. (“ASUS”) (and its subsidiaries, Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”) and Emerald Coast Utility Services ("ECUS")). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” GSWC is a public utility engaged principally in the purchase, production, distribution and sale of water in California serving approximately 261,000 customers. GSWC also distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,000 customers through its Bear Valley Electric Service (“BVES”) division. Although Registrant has a diversified base of residential, industrial and other customers, revenues derived from commercial and residential water customers accounted for approximately 90% of total water revenues during the three months ended March 31, 2017 and 2016. The California Public Utilities Commission (“CPUC”) regulates GSWC’s water and electric businesses in matters including properties, rates, services, facilities and transactions by GSWC with its affiliates. AWR’s assets and operating income are primarily those of GSWC. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various United States military bases pursuant to 50-year firm fixed-price contracts. These contracts are subject to periodic price redeterminations or economic price adjustments and modifications for changes in circumstances, changes in laws and regulations and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation: The consolidated financial statements and notes thereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. AWR owns all the outstanding Common Shares of GSWC and ASUS. ASUS owns all of the outstanding Common Shares of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries, all of which are wholly owned. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. Inter-company transactions and balances have been eliminated in the AWR consolidated financial statements. The consolidated financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The December 31, 2016 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles ("GAAP") in the United States of America. The preparation of the consolidated financial statements 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 these estimates. In the opinion of management, all adjustments consisting of normal, recurring items and estimates necessary for a fair statement of the results for the interim periods have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2016 filed with the SEC. GSWC's Related Party Transactions: GSWC and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC also allocates certain corporate office administrative and general costs to its affiliate, ASUS, using allocation factors approved by the CPUC. During each of the three-month periods ended March 31, 2017 and 2016, GSWC allocated to ASUS approximately $1.0 million of corporate office administrative and general costs. In addition, AWR has a $150.0 million syndicated credit facility. AWR borrows under this facility and provides funds to its subsidiaries, including GSWC, in support of their operations. The interest rate charged to GSWC and ASUS is sufficient to cover AWR’s interest cost under the credit facility. In October 2015, AWR issued interest bearing promissory notes (the "Notes") to GSWC and ASUS for $40 million and $10 million, respectively, which expire on May 23, 2018. Under the terms of these Notes, AWR may borrow from GSWC and ASUS amounts up to $40 million and $10 million, respectively, for working capital purposes. AWR agrees to pay any unpaid principal amounts outstanding under these notes, plus accrued interest. As of March 31, 2017 and 2016, there were no amounts outstanding under these Notes. Sales and Use Taxes: GSWC bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which GSWC pays to various municipalities (based on ordinances adopted by these municipalities) to use public rights of way for utility purposes. GSWC bills these franchise fees to its customers based on a CPUC-authorized rate for each rate-making area as applicable. These franchise fees, which are required to be paid regardless of GSWC’s ability to collect them from its customer, are accounted for on a gross basis. GSWC’s franchise fees billed to customers and recorded as operating revenue were approximately $827,000 and $867,000 for the three months ended March 31, 2017 and 2016, respectively. When GSWC acts as an agent, and the tax is not required to be remitted if it is not collected from the customer, the taxes are accounted for on a net basis. Recently Issued Accounting Pronouncements: In March 2016, the FASB issued Accounting Standard Update 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends ASC Topic 718, Compensation - Stock Compensation. Under the new guidance, the tax effects related to share-based payments at settlement (or expiration) will be required to be recorded through the income statement rather than through equity, further increasing the volatility of income tax expense. The new standard also removes the requirement to delay recognition of a windfall tax benefit until an employer reduces its current taxes payable. It also permits entities to make an accounting policy election for the impact of forfeitures on the recognition of expense for shared-based payment awards. Income tax benefits in excess of compensation costs or tax deficiencies for share-based compensation are recorded to the income tax provision, instead of to Registrant's shareholders' equity, which can impact the effective tax rate. The standard was effective January 1, 2017 and did not have a significant impact on Registrant's net earnings (see Note 6). On a prospective basis, the excess tax benefits are classified as an operating activity along with other income tax cash flows on the statement of cash flows. In May 2014, the FASB issued updated accounting guidance on revenue recognition. Under this guidance, an entity recognizes revenue when it transfers promised goods or services to customers in an amount that reflects what the entity expects in exchange for the goods or services. The guidance also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, and adoption is not permitted earlier than 2017. The guidance allows entities to select one of two methods of adoption, either the full retrospective approach, meaning the guidance would be applied to all periods presented, or modified retrospective approach, meaning the cumulative effect of applying the guidance would be recognized as an adjustment to opening retained earnings at January 1, 2018, along with providing certain additional disclosures. Registrant intends to use the modified retrospective approach beginning January 1, 2018. Management continues to assess all potential impacts of the standard, and does not believe the new standard will have an impact on GSWC's revenues for water and electric services. In instances where construction contracts contain more than one distinct good or service, as defined by the standard, the new standard may affect the timing of when Registrant recognizes contracted services revenue. In February 2016, the FASB issued a new lease accounting standard, Leases (ASC 842). Under the new guidance, lessees will recognize a right-of-use asset and a lease liability for virtually all leases (other than leases that meet the definition of a short-term lease). For income statement purposes, leases will be classified as either operating or finance. Operating leases will result in straight-line expense while finance leases will result in a front-loaded expense pattern. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Management has not yet determined the effect of the standard on the Company's ongoing financial reporting. In March 2017, the FASB issued Accounting Standards Update 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost, which changes the financial statement presentation of the cost of defined benefit pension plans and other retirement benefits. Under current GAAP, the components of net benefit cost for retirement plans (such as service cost, interest cost, expected return on assets, and the amortization of various deferred items), are aggregated as operating costs for financial statement presentation purposes. Under the new guidance, the service cost component will continue to be presented as operating costs, while all other components of net benefit cost will be presented outside of operating income. The adopted changes do not change any of the recognition and measurement provisions of current retirement benefits accounting. The new guidance is effective for annual and interim periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of this new standard on its statements of income, and expects to adopt the standard beginning in 2018. |

| Regulated Operations [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Regulatory Matters | Regulatory Matters: In accordance with accounting principles for rate-regulated enterprises, Registrant records regulatory assets, which represent probable future recovery of costs from customers through the ratemaking process, and regulatory liabilities, which represent probable future refunds that are to be credited to customers through the ratemaking process. At March 31, 2017, Registrant had approximately $58.0 million of regulatory assets, net of regulatory liabilities, not accruing carrying costs. Of this amount, $26.6 million relates to the underfunded position in Registrant's pension and other post-retirement obligations, $5.5 million relates to a memorandum account authorized by the CPUC to track unrealized gains and losses on BVES' purchase power contracts over the term of the contracts, and $20.7 million relates to deferred income taxes representing accelerated tax benefits flowed through to customers, which will be included in rates concurrently with recognition of the associated future tax expense. The remainder relates to other items that do not provide for or incur carrying costs. Regulatory assets represent costs incurred by GSWC for which it has received or expects to receive rate recovery in the future. In determining the probability of costs being recognized in other periods, GSWC considers regulatory rules and decisions, past practices, and other facts or circumstances that would indicate if recovery is probable. If the CPUC determines that a portion of GSWC’s assets are not recoverable in customer rates, GSWC must determine if it has suffered an asset impairment that requires it to write-down the assets’ value. Regulatory assets are offset against regulatory liabilities within each rate-making area. Amounts expected to be collected or refunded in the next 12-months have been classified as current assets and current liabilities by rate-making area. Regulatory assets, less regulatory liabilities, included in the consolidated balance sheets are as follows:
Regulatory matters are discussed in detail in the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2016 filed with the SEC. The discussion below focuses on significant matters and developments since December 31, 2016. Alternative-Revenue Programs: GSWC records the difference between what it bills its water customers and that which is authorized by the CPUC using the Water Revenue Adjustment Mechanism (“WRAM”) and Modified Cost Balancing Account (“MCBA”) accounts approved by the CPUC. The over- or under-collection of the WRAM is netted against the MCBA over- or under-collection for the corresponding rate-making area and bears interest at the current 90-day commercial paper rate. GSWC has implemented surcharges to recover its WRAM/MCBA balances as of December 31, 2016. For the three months ended March 31, 2017 and 2016, surcharges (net of surcredits) of approximately $4.0 million and $1.4 million, respectively, were billed to customers to recover previously incurred under-collections in the WRAM/MCBA accounts. During the three months ended March 31, 2017, GSWC recorded additional net under-collections of $11.6 million in the WRAM/MCBA accounts. As of March 31, 2017, GSWC had a net aggregated regulatory asset of $55.3 million which is comprised of a $40.0 million under-collection in the WRAM accounts and $15.3 million under-collection in the MCBA accounts. As required by the accounting guidance for alternative revenue programs, GSWC is required to collect its WRAM balances, net of its MCBA, within 24 months following the year in which an under-collection is recorded. In April 2012, the CPUC set the recovery period for under-collected balances that are up to 15% of adopted annual revenues at 18 months or less. For under-collected balances greater than 15%, the recovery period is 19 to 36 months. As of March 31, 2017, the recovery periods for GSWC's WRAM/MCBA balances are primarily within the 12 to 18-month period; however, there were some ratemaking areas that had recovery periods related to the 2015 WRAM balances that are greater than 24 months. As a result, during the fourth quarter of 2015, GSWC did not record $1.4 million of the 2015 WRAM under-collection balance as revenue. This amount is being recognized as revenue when it is determined that it will be collected within 24 months and, therefore, approximately $320,000 and $910,000 was recognized during the first quarter of 2017 and during the year ended December 31, 2016, respectively, with the remaining balance to be recognized in future periods. Water General Rate Case: In December 2016, the CPUC issued a decision in GSWC's water general rate case for all its water ratemaking areas and the general office to determine new rates for the years 2016, 2017 and 2018. The new rates approved were retroactive to January 1, 2016. However, because of the delay in issuing a decision, the CPUC ordered GSWC to bypass implementing 2016 rates and to implement 2017 rates after the correction of some minor rate calculations in the December 2016 decision, which the CPUC completed and subsequently issued a final decision in March 2017. Any revenue shortfall due to differences between the actual rates charged in 2016 and early 2017 while the decision was still pending and the new rates adopted in the March 2017 final decision will be recovered through a rate surcharge. The new rates were implemented in April 2017. Because of the delay in the final decision, GSWC accumulated $10.2 million in its general rate case memorandum accounts as of March 31, 2017, the majority of which were accumulated during 2016, representing the rate difference between interim rates and final rates authorized by the CPUC in March 2017, retroactive to January 1, 2016. Surcharges are expected to be implemented later in 2017 to recover the retroactive rate difference over approximately 12 - 24 months for the majority of GSWC's water ratemaking areas. Other Regulatory Matters: Cost of capital application In early April 2017, GSWC filed its water cost of capital application with the CPUC. The application filed with the CPUC recommends an overall weighted return on rate base of 9.11%, including an updated cost of debt of 6.6% and a return on equity ("ROE") of 11%. The current authorized return on rate base is 8.34%, including an ROE of 9.43%. A decision on the application is scheduled to be received by the end of 2017 and to become effective January 1, 2018. At this time, management cannot predict the outcome of this application and whether the CPUC will approve GSWC's request. Formal Complaint Filed with the CPUC In June 2016, a third party filed a formal complaint with the CPUC against GSWC about a water main break that occurred in 2014 causing damage to a commercial building. Repairs to the building have been delayed for a variety of reasons, including a dispute and litigation between two of GSWC's insurance carriers regarding their respective coverage obligations, as well as questions as to the nature and extent of the building’s damage and the costs associated therewith. The complaint filed with the CPUC requests, among other things, that the CPUC investigate the main break, the damage to the commercial building and the delay of its repairs, and order GSWC to immediately complete repairs. GSWC believes it has reasonable defenses to the complaint filed with the CPUC. In July 2016, GSWC filed an answer to the formal complaint with the CPUC as well as a motion to dismiss the complaint. Previously, the owners of the commercial building filed suit in Ventura County Superior Court against GSWC for damages to the building. The trial of this lawsuit is expected to begin in May 2017. GSWC believes it has sufficient insurance coverage to cover any judgment entered in the civil suit pending in Superior Court. However, GSWC cannot predict the outcome of the Superior Court litigation, the dispute and litigation between its insurers, or the CPUC proceeding, and as a result, cannot make an estimate of a loss or range of loss, if any, at this time. |

| Earnings per Share/Capital Stock | Earnings per Share/Capital Stock: In accordance with the accounting guidance for participating securities and earnings per share (“EPS”), Registrant uses the “two-class” method of computing EPS. The “two-class” method is an earnings allocation formula that determines EPS for each class of common stock and participating security. AWR has participating securities related to restricted stock units that earn dividend equivalents on an equal basis with AWR’s Common Shares that have been issued under AWR's Stock Incentive Plans for employees and the Non-Employee Directors Stock Plans. In applying the “two-class” method, undistributed earnings are allocated to both common shares and participating securities. The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding used for calculating basic net income per share:
Diluted EPS is based upon the weighted average number of Common Shares, including both outstanding shares and shares potentially issuable pursuant to stock options and restricted stock units granted under AWR’s Stock Incentive Plans for employees and the Non-Employee Directors Stock Plans, and net income. At March 31, 2017 and 2016, there were 120,138 and 142,402 options outstanding, respectively, under these Plans. At March 31, 2017 and 2016, there were also 194,031 and 215,129 restricted stock units outstanding, respectively, including performance shares awarded to officers of the Registrant. The following is a reconciliation of Registrant’s net income and weighted average Common Shares outstanding for calculating diluted net income per share:
(1) In applying the treasury stock method of reflecting the dilutive effect of outstanding stock-based compensation in the calculation of diluted EPS, 120,138 and 142,402 stock options at March 31, 2017 and 2016, respectively, were deemed to be outstanding in accordance with the accounting guidance on earnings per share. All the 194,031 and 215,129 restricted stock units at March 31, 2017 and 2016, respectively, were included in the calculation of diluted EPS for the three months ended March 31, 2017 and 2016. No stock options outstanding at March 31, 2017 had an exercise price greater than the average market price of AWR’s Common Shares for the three months ended March 31, 2017. There were no stock options outstanding at March 31, 2017 or 2016 that were anti-dilutive. During the three months ended March 31, 2017 and 2016, AWR issued 44,832 and 52,153 common shares for approximately $35,000 and $126,000, respectively, under Registrant’s Common Share Purchase and Dividend Reinvestment Plan, the 401(k) Plan, the Stock Incentive Plans for employees, and the Non-Employee Directors Stock Plans. During the three months ended March 31, 2017 and 2016, AWR paid quarterly dividends of approximately $8.9 million, or $0.242 per share, and $8.2 million, or $0.224 per share, respectively. |

| Derivative Instruments and Hedging Activities Disclosure [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Derivative Instruments | Derivative Instruments: Derivative financial instruments are used to manage exposure to commodity price risk. Commodity price risk represents the potential impact that can be caused by a change in the market value of a commodity. BVES purchases power under long-term contracts at a fixed cost depending on the amount of power and the period during which the power is purchased under such contracts. In December 2014, the CPUC approved an application that allowed BVES to immediately execute new long-term purchased power contracts with energy providers on December 9, 2014. BVES began taking power under these long-term contracts effective January 1, 2015 at a fixed cost over three and five year terms depending on the amount of power and period during which the power is purchased under the contracts. The long-term contracts executed in December 2014 are subject to the accounting guidance for derivatives and require mark-to-market derivative accounting. Among other things, the CPUC also authorized GSWC to establish a regulatory asset and liability memorandum account to offset the mark-to-market entries required by the accounting guidance. Accordingly, all unrealized gains and losses generated from the purchased power contracts executed in December 2014 are deferred monthly into a non-interest bearing regulatory memorandum account that tracks the changes in fair value of the derivative throughout the term of the contract. As a result, these unrealized gains and losses do not impact GSWC’s earnings. As of March 31, 2017, there was a $5.5 million unrealized loss in the memorandum account for the purchased power contracts due to the drop in energy prices since entering into the contracts. The notional volumes remaining under these long-term contracts as of March 31, 2017 was approximately 306,000 megawatt hours. The accounting guidance for fair value measurements applies to all financial assets and financial liabilities that are being measured and reported on a fair value basis. Under the accounting guidance, GSWC makes fair value measurements that are classified and disclosed in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices in markets that are not active or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; or Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). To value the contracts, Registrant applies the Black-76 model, utilizing various inputs that include quoted market prices for energy over the duration of the contracts. The market prices used to determine the fair value for this derivative instrument were estimated based on independent sources such as broker quotes and publications that are not observable in or corroborated by the market. Registrant received one broker quote to determine the fair value of its derivative instrument. When such inputs have a significant impact on the measurement of fair value, the instrument is categorized as Level 3. Accordingly, the valuation of the derivative on Registrant’s purchased power contract has been classified as Level 3 for all periods presented. The following table presents changes in the fair value of GSWC’s Level 3 derivatives for the three months ended March 31, 2017 and 2016:

| Fair Value Disclosures [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fair Value of Financial Instruments | Fair Value of Financial Instruments: For cash and cash equivalents, accounts receivable, accounts payable and short-term debt, the carrying amount is assumed to approximate fair value due to the short-term nature of the amounts. Investments held in a Rabbi Trust for the supplemental executive retirement plan are measured at fair value and totaled $12.5 million as of March 31, 2017. All equity investments in the Rabbi Trust are Level 1 investments in mutual funds. The investments held in the Rabbi Trust are included in Other Property and Investments on Registrant's balance sheets. The table below estimates the fair value of long-term debt held by GSWC. The fair values as of March 31, 2017 and December 31, 2016 were determined using rates for similar financial instruments of the same duration utilizing Level 2 methods and assumptions. The interest rates used for the March 31, 2017 valuation decreased as compared to December 31, 2016, increasing the fair value of long-term debt as of March 31, 2017. Changes in the assumptions will produce differing results.

Income Taxes: |

| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes: AWR's consolidated effective tax rate (“ETR”) was 35.1% for the three months ended March 31, 2017 as compared to 36.4% for the three months ended March 31, 2016. GSWC's ETR was 36.9% for the three months ended March 31, 2017 as compared to 37.7% for the three months ended March 31, 2016. For the three months ended March 31, 2017, the ETR was affected by the adoption of the new accounting standard update for share-based payments (see Note 1). Under the new guidance, the tax effects related to share-based payments are recorded through the income statement. Previously, tax benefits in excess of compensation cost ("windfalls") and tax deficiencies ("shortfalls") were recorded directly to equity. AWR and GSWC adopted the guidance effective January 1, 2017 and, therefore, all excess tax benefits resulting from share-based payments during the three months ended March 31, 2017 were reflected in the income statements, which resulted in a reduction to income tax expense for AWR and GSWC of approximately $412,000 and $374,000, respectively. For the three months ended March 31, 2017 and 2016, the ETR at the AWR consolidated level also fluctuated as a result of certain permanent differences recorded at AWR (parent) and ASUS and its subsidiaries, as well as state taxes recorded at AWR (parent) and ASUS and its subsidiaries (where the amounts of state taxes vary among the jurisdictions in which they operate). For the three months ended March 31, 2017 and 2016, GSWC's ETR also deviated from the statutory rate due to state tax and differences between book and taxable income that are treated as flow-through adjustments in accordance with regulatory requirements (principally plant-, rate-case- and compensation-related items). As a regulated utility, GSWC treats certain temporary differences as flow-through adjustments in computing its income tax provision consistent with the income tax approach approved by the CPUC for ratemaking purposes. Flow-through adjustments increase or decrease tax expense in one period, with an offsetting decrease or increase occurring in another period. Giving effect to these temporary differences as flow-through adjustments typically results in a greater variance between the ETR and the statutory federal income tax rate in any given period than would otherwise exist if GSWC were not required to account for its income taxes as a regulated enterprise. Changes in Tax Law: In December 2015, the Protecting Americans From Tax Hikes Act of 2015 extended bonus depreciation for qualifying property through 2019. For 2015 through 2017, bonus depreciation was extended at a 50% rate. For 2018 and 2019, bonus depreciation will be phased down to 40% and 30%, respectively. Although the change in law reduces AWR’s current taxes payable over these years, it does not reduce its total income tax expense or ETR. |

Registrant expects to contribute approximately $6.2 million to its pension plan during 2017. Regulatory Adjustment: As authorized by the CPUC in the most recent water and electric general rate case decisions, GSWC utilizes two-way balancing accounts for its water and electric regions and the general office to track differences between the forecasted annual pension expenses in rates or expected to be in rates and the actual annual expense recorded by GSWC in accordance with the accounting guidance for pension costs. As of March 31, 2017, GSWC has a total $900,000 net under-collection in the two-way pension balancing accounts included as part of the pension regulatory asset (Note 2). |

| Commitments and Contingencies Disclosure [Abstract] | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Contingencies and Assets Held for Sale | Contingencies and Assets Held for Sale: Condemnation of Properties: The laws of the State of California provide for the acquisition of public utility property by governmental agencies through their power of eminent domain, also known as condemnation, where doing so is necessary and in the public interest. In addition, these laws provide that the owner of utility property (i) may contest whether the condemnation is necessary and in the public interest, and (ii) is entitled to receive the fair market value of its property if the property is ultimately taken. Claremont System: In December 2014, the City of Claremont, California filed a complaint in eminent domain against GSWC. The trial determining the City of Claremont's right to seize the system by eminent domain concluded in August 2016. On December 9, 2016, the County of Los Angeles Superior Court issued a decision rejecting the City of Claremont’s attempt to take over GSWC’s Claremont water system. On February 2, 2017, the City of Claremont filed an appeal to the decision. Registrant is unable predict the outcome of the appeal. GSWC serves approximately 11,000 customers in Claremont. Ojai System: On April 12, 2017, the Board of Directors of Casitas Municipal Water District (“Casitas”) approved a settlement agreement with GSWC, and a group of citizens referred to as Ojai Friends of Locally Owned Water (“Ojai FLOW”) to resolve the eminent domain action and other litigation brought by Casitas and Ojai FLOW against GSWC. Under the terms of the settlement agreement, Casitas will acquire the operating assets of GSWC’s Ojai water system by eminent domain for approximately $34.5 million in cash, including payments for customer receivables and regulatory assets subject to a post-closing final reconciliation. Under the agreement, Casitas and Ojai FLOW have also agreed to dismiss all claims against GSWC, which claims sought damages against GSWC stemming from Casitas’ proposal to issue bonds to finance the acquisition of GSWC’s Ojai water system. The transaction is expected to close in June 2017 following satisfaction of all closing conditions. Upon closing, GSWC expects to recognize a pretax gain on the sale of assets of approximately $8.0 million. As of March 31, 2017, the assets and liabilities related to the Ojai water system to be acquired and assumed by Casitas have been classified as assets and liabilities held for sale on Registrant's balance sheets as follows:
Environmental Clean-Up and Remediation: GSWC has been involved in environmental remediation and cleanup at a plant site ("Chadron Plant") that contained an underground storage tank which was used to store gasoline for its vehicles. This tank was removed from the ground in July 1990 along with the dispenser and ancillary piping. Since then, GSWC has been involved in various remediation activities at this site. Analysis indicates that off-site monitoring wells may be necessary to document effectiveness of remediation. As of March 31, 2017, the total spent to clean-up and remediate GSWC’s plant facility was approximately $5.2 million, of which $1.5 million has been paid by the State of California Underground Storage Tank Fund. Amounts paid by GSWC have been included in rate base and approved by the CPUC for recovery. As of March 31, 2017, GSWC has a regulatory asset and an accrued liability for the estimated additional cost of $1.4 million to complete the cleanup at the site. The estimate includes costs for two years of continued activities of groundwater cleanup and monitoring, future soil treatment and site-closure-related activities. The ultimate cost may vary as there are many unknowns in remediation of underground gasoline spills and this is an estimate based on currently available information. Management also believes it is probable that the estimated additional costs will be approved in rate base by the CPUC. Other Litigation: Registrant is also subject to other ordinary routine litigation incidental to its business, some of which may include claims for compensatory and punitive damages. Management believes that rate recovery, proper insurance coverage and reserves are in place to insure against, among other things, property, general liability, employment, and workers’ compensation claims incurred in the ordinary course of business; however, insurance coverage may not cover certain claims involving punitive damages. Registrant is unable to predict an estimate of the loss, if any, resulting from any pending suits or administrative proceedings. |

| Business Segments | Business Segments: AWR has three reportable segments, water, electric and contracted services, whereas GSWC has two segments, water and electric. On a stand-alone basis, AWR has no material assets other than its investments in its subsidiaries. All activities of GSWC, a rate-regulated utility, are geographically located within California. Activities of ASUS and its subsidiaries are conducted in California, Georgia, Florida, Maryland, New Mexico, North Carolina, South Carolina, Texas and Virginia. Each of the Military Utility Privatization Subsidiaries is regulated, if applicable, by the state in which the subsidiary primarily conducts water and/or wastewater operations. Fees charged for operations and maintenance, and renewal and replacement services are based upon the terms of the contracts with the U.S. government, which have been filed, as appropriate, with the commissions in the states in which ASUS’s subsidiaries are incorporated. The tables below set forth information relating to GSWC’s operating segments, ASUS and its subsidiaries and other matters. Total assets by segment are not presented below, as certain of Registrant’s assets are not tracked by segment. The utility plant amounts are net of respective accumulated provisions for depreciation.

Summary of Significant Accounting Policies: (Policies) |
3 Months Ended |
|---|---|
Mar. 31, 2017 | |
| Accounting Policies [Abstract] | |
| Nature of Operations | Nature of Operations: American States Water Company (“AWR”) is the parent company of Golden State Water Company (“GSWC”) and American States Utility Services, Inc. (“ASUS”) (and its subsidiaries, Fort Bliss Water Services Company (“FBWS”), Terrapin Utility Services, Inc. (“TUS”), Old Dominion Utility Services, Inc. (“ODUS”), Palmetto State Utility Services, Inc. (“PSUS”), Old North Utility Services, Inc. (“ONUS”) and Emerald Coast Utility Services ("ECUS")). The subsidiaries of ASUS are collectively referred to as the “Military Utility Privatization Subsidiaries.” GSWC is a public utility engaged principally in the purchase, production, distribution and sale of water in California serving approximately 261,000 customers. GSWC also distributes electricity in several San Bernardino County mountain communities in California serving approximately 24,000 customers through its Bear Valley Electric Service (“BVES”) division. Although Registrant has a diversified base of residential, industrial and other customers, revenues derived from commercial and residential water customers accounted for approximately 90% of total water revenues during the three months ended March 31, 2017 and 2016. The California Public Utilities Commission (“CPUC”) regulates GSWC’s water and electric businesses in matters including properties, rates, services, facilities and transactions by GSWC with its affiliates. AWR’s assets and operating income are primarily those of GSWC. ASUS, through its wholly owned subsidiaries, operates, maintains and performs construction activities (including renewal and replacement capital work) on water and/or wastewater systems at various United States military bases pursuant to 50-year firm fixed-price contracts. These contracts are subject to periodic price redeterminations or economic price adjustments and modifications for changes in circumstances, changes in laws and regulations and additions to the contract value for new construction of facilities at the military bases. There is no direct regulatory oversight by the CPUC over AWR or the operations, rates or services provided by ASUS or any of its wholly owned subsidiaries. Basis of Presentation: The consolidated financial statements and notes thereto are presented in a combined report filed by two separate Registrants: AWR and GSWC. References in this report to “Registrant” are to AWR and GSWC, collectively, unless otherwise specified. AWR owns all the outstanding Common Shares of GSWC and ASUS. ASUS owns all of the outstanding Common Shares of the Military Utility Privatization Subsidiaries. The consolidated financial statements of AWR include the accounts of AWR and its subsidiaries, all of which are wholly owned. These financial statements are prepared in conformity with accounting principles generally accepted in the United States of America. Inter-company transactions and balances have been eliminated in the AWR consolidated financial statements. The consolidated financial statements included herein have been prepared by Registrant, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). The December 31, 2016 condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by generally accepted accounting principles ("GAAP") in the United States of America. The preparation of the consolidated financial statements 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 these estimates. In the opinion of management, all adjustments consisting of normal, recurring items and estimates necessary for a fair statement of the results for the interim periods have been made. It is suggested that these consolidated financial statements be read in conjunction with the consolidated financial statements and the notes thereto included in the Form 10-K for the year ended December 31, 2016 filed with the SEC. |
| GSWC's Related Party Transactions | GSWC's Related Party Transactions: GSWC and ASUS provide and/or receive various support services to and from their parent, AWR, and among themselves. GSWC also allocates certain corporate office administrative and general costs to its affiliate, ASUS, using allocation factors approved by the CPUC. During each of the three-month periods ended March 31, 2017 and 2016, GSWC allocated to ASUS approximately $1.0 million of corporate office administrative and general costs. In addition, AWR has a $150.0 million syndicated credit facility. AWR borrows under this facility and provides funds to its subsidiaries, including GSWC, in support of their operations. The interest rate charged to GSWC and ASUS is sufficient to cover AWR’s interest cost under the credit facility. In October 2015, AWR issued interest bearing promissory notes (the "Notes") to GSWC and ASUS for $40 million and $10 million, respectively, which expire on May 23, 2018. Under the terms of these Notes, AWR may borrow from GSWC and ASUS amounts up to $40 million and $10 million, respectively, for working capital purposes. AWR agrees to pay any unpaid principal amounts outstanding under these notes, plus accrued interest. As of March 31, 2017 and 2016, there were no amounts outstanding under these Notes. |
| Sales and Use Taxes | Sales and Use Taxes: GSWC bills certain sales and use taxes levied by state or local governments to its customers. Included in these sales and use taxes are franchise fees, which GSWC pays to various municipalities (based on ordinances adopted by these municipalities) to use public rights of way for utility purposes. GSWC bills these franchise fees to its customers based on a CPUC-authorized rate for each rate-making area as applicable. These franchise fees, which are required to be paid regardless of GSWC’s ability to collect them from its customer, are accounted for on a gross basis. GSWC’s franchise fees billed to customers and recorded as operating revenue were approximately $827,000 and $867,000 for the three months ended March 31, 2017 and 2016, respectively. When GSWC acts as an agent, and the tax is not required to be remitted if it is not collected from the customer, the taxes are accounted for on a net basis. |
| Recently Issued Accounting Pronouncements | Recently Issued Accounting Pronouncements: In March 2016, the FASB issued Accounting Standard Update 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends ASC Topic 718, Compensation - Stock Compensation.
