	Sep. 30, 2014
Accounting Policies [Abstract]	'
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	'
	Note 1 — The Company and Summary of Significant Accounting Policies
	The Company
	Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our”, or “us”) designs, develops, manufactures, and sells energy recovery devices that transform untapped energy into reusable energy from industrial fluid flows and pressure cycles. Our products are marketed and sold in fluid flow markets, such as desalination and oil and gas, under the trademarks ERI®, PX®, Pressure Exchanger®, PX Pressure Exchanger®, IsoBoost™, IsoGen™, and IsoPro™. Our products are developed and manufactured in the United States of America (“U.S.”) at our headquarters in San Leandro, California. We also have sales offices in Madrid, Spain; Dubai, United Arab Emirates; and Shanghai, Peoples Republic of China.
	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires our management to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Our more significant estimates and judgments that we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration. Actual results could differ materially from those estimates.
	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The accompanying condensed consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The December 31, 2013 condensed consolidated balance sheet was derived from audited financial statements, and may not include all disclosures required by U.S. GAAP; however, we believe that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2013 included in our Annual Report on Form 10-K filed with the SEC on March 11, 2014.
	In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.
	Change in Method of Accounting for Inventory Valuation
	Prior to January 1, 2014, inventories were stated at the lower of cost (using the weighted average cost method) or market. Effective January 1, 2014, with the final implementation of our new enterprise resource planning (“ERP”) system, we changed our method of accounting for inventories to the first-in, first-out (“FIFO”) method. We believe that the change is preferable, as the FIFO method better reflects the current value of inventories and provides more accurate matching of manufacturing costs and revenues. Due to the limited capabilities of our former ERP system, we determined that it was impracticable to retrospectively apply the FIFO costing method to prior periods. As such, prior period consolidated financial statements have not been retroactively adjusted. The cumulative effect of this change was not material.
	Recent Accounting Pronouncements
	On May 28, 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The amendment requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is January 1, 2017 for us. Early application is not permitted. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

	Note 3 — Loss per Share
	Basic and diluted net loss per share is based on the weighted average number of common shares outstanding during the period. Potential dilutive securities are excluded from the calculation of loss per share, as their inclusion would be anti-dilutive.
	The following table shows the computation of basic and diluted loss per share (in thousands, except per share data):

	We acquired Pump Engineering, LLC in December 2009. Under the terms of the purchase agreement, $3.5 million of consideration was contingent upon achievement of certain performance milestones. These performance milestones were tied to: (i) achieving certain minimum product energy efficiency metrics ($1.3 million); (ii) meeting certain product delivery time schedules ($1.2 million); and (iii) meeting certain product warranty metrics ($1.0 million). During the fourth quarter of 2010, the first two performance milestones were not met. Accordingly, we withheld payment of $2.5 million under the contractual terms of the purchase agreement.
	In August 2011, the former shareholders of Pump Engineering, LLC filed a claim against us seeking damages in the amount of $2.5 million and their litigation costs. As a result, we restricted cash of $3.5 million, the entire amount of the original contingent consideration in an escrow account. On August 8, 2014, we entered into a settlement agreement (the “Agreement”) in this matter. Under the Agreement, we received $2.125 million from the established escrow account, and the plaintiffs received $1.375 million from the said escrow account with neither party admitting to any liability or responsibility. The $3.5 million of restricted cash related to the amount held in escrow was released.

	Note 6 — Lines of Credit
	Lines of Credit
	In June 2012, we entered into a loan agreement (the “2012 Agreement”) with a financial institution. The 2012 Agreement provides for a total available credit line of $16.0 million. Under the 2012 Agreement, we are allowed to draw advances not to exceed, at any time, $10.0 million as revolving loans. The total stand-by letters of credit issued under the 2012 Agreement may not exceed the lesser of the $16.0 million credit line or the credit line minus all outstanding revolving loans. At no time may the aggregate of the revolving loans and stand-by letters of credit exceed the total available credit line of $16.0 million. Revolving loans may be in the form of a base rate loan that bears interest equal to the prime rate plus 0% or a Eurodollar loan that bears interest equal to the adjusted LIBOR plus 1.25%. Stand-by letters of credit are subject to customary fees and expenses for issuance or renewal. The unused portion of the credit facility is subject to a facility fee in an amount equal to 0.25% per annum of the average unused portion of the revolving line. The 2012 Agreement also requires us to maintain a cash collateral balance equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of credit. The 2012 Agreement matures in June 2015 and is collateralized by substantially all of our assets. As of September 30, 2014 and December 31, 2013, there were no advances drawn under the 2012 Agreement. Stand-by letters of credit collateralized under the 2012 Agreement totaled $2.7 million and $1.3 million as of September 30, 2014 and December 31, 2013, respectively. Total cash restricted related to these stand-by letters of credit totaled $2.7 million and $1.3 million as of September 30, 2014 and December 31, 2013, respectively.
	We are subject to certain financial and administrative covenants under the 2012 Agreement. As of September 30, 2014, we were in compliance with these covenants.
	In 2009, we entered into a loan and security agreement (the “2009 Agreement”) with another financial institution. The 2009 Agreement, as amended, provided a total available credit line of $16.0 million. Under the 2009 Agreement, we were allowed to draw advances of up to $10.0 million on a revolving line of credit or utilize up to $15.9 million as collateral for stand-by letters of credit, provided that the aggregate of the outstanding advances and collateral did not exceed the total available credit line of $16.0 million. Advances under the revolving line of credit incurred interest based on a prime rate index or LIBOR plus 1.375%. The 2009 Agreement, as amended, also required us to maintain cash collateral balances equal to at least 101% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit and 100% of the amount of all outstanding advances. The 2009 Agreement expired at the end of May 2012, at which time we became required to maintain a cash collateral balance equal to at least 105% of the face amount of all outstanding stand-by letters of credit collateralized by the line of credit. There were no advances drawn under the 2009 Agreement’s credit line at the time it expired. Remaining stand-by letters of credit issued under the 2009 Agreement totaled $2.3 million and $3.6 million as of September 30, 2014 and December 31, 2013, respectively. Total cash restricted related to these stand-by letters of credit totaled $2.4 million and $3.7 million as of September 30, 2014 and December 31, 2013, respectively.

	Stock Repurchase Program
	In February 2014, our Board of Directors authorized a stock repurchase program under which up to three million shares, not to exceed $6.0 million in aggregate cost, of our outstanding common stock could be repurchased through December 31, 2014 at the discretion of management. We account for treasury stock using the cost method. Cost includes fees charged in connection with acquiring the treasury stock. During the three months ended September 30, 2014, 252,300 shares at an aggregate cost of $1.0 million were repurchased under this authorization. During the nine months ended September 30, 2014, 367,600 shares at an aggregate cost of $1.6 million were repurchased under this authorization.
	In October 2014, an additional 329,253 shares at an aggregate cost of $1.2 million were repurchased under this authorization.
	Share-Based Compensation Expense
	For the three and nine months ended September 30, 2014 and 2013, we recognized share-based compensation expense related to employees and consultants as follows (in thousands):
		Three Months Ended				Nine Months Ended

	As of September 30, 2014, total unrecognized compensation cost related to non-vested share-based awards, net of estimated forfeitures, was $3.9 million, which is expected to be recognized as expense over a weighted average period of approximately 2.98 years.
	In March 2014, we granted 957,000 stock options to certain officers and other employees. The options vest over a four-year period, have an exercise price of $6.00 per share, and expire 10 years from the grant date.
	Also, in March 2014, we granted 10,000 stock options to an employee. The options vest over a four-year period, have an exercise price of $5.32 per share, and expire 10 years from the grant date.
	In April 2014, we granted 440,000 stock options to our President and Chief Executive Officer in lieu of his participation in the 2014 cash incentive plan. The options vest over a four-year period, have an exercise price of $4.96 per share, and expire 10 years from the grant date.
	In June 2014, we granted 50,000 stock options to a certain employee as part of the offer letter of employment. The options vest over a four-year period, have an exercise price of $5.91 per share, and expire 10 years from the grant date.
	In July 2014, we granted 100,000 stock options to our new Chief Financial Officer as part of his promotion. The options vest over a four-year period, have an exercise price of $4.91 per share, and expire 10 years from the grant date.
	On October 1, 2014, we granted 100,000 and 180,000 stock options to our new Chief Financial Officer as the second part of his promotion and to certain other employees, respectively. The options vest over a four-year period, have an exercise price of $3.31 per share, and expire 10 years from the grant date.
	On October 15, 2014, we granted 75,000 stock options to our new Chief Sales Officer as part of his offer letter of employment. The options vest over a four-year period, have an exercise price of $3.80 per share, and expire 10 years from the grant date.
	Warrants
	On July 29, 2014, warrants to purchase 400,000 shares of common stock were exercised for 311,111 shares in lieu of cash proceeds. The remaining 88,889 warrants were cancelled and considered payment for the exercise.

	Based on management’s analysis of warranty liability experience, a change in estimate of our warranty reserve of $132,000 was recorded in 2013.
	Purchase Obligations
	We enter into purchase order arrangements with our vendors. As of September 30, 2014, there were open purchase orders for which we had not yet received the related goods or services. These arrangements are subject to change based on our sales demand forecasts, and we have the right to cancel the arrangements prior to the date of delivery. As of September 30, 2014, we had approximately $1.8 million of cancellable open purchase order arrangements related primarily to materials and parts.
	Guarantees
	We enter into indemnification provisions under our agreements with other companies in the ordinary course of business, typically with customers. Under these provisions, we generally indemnify and hold harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of our activities, generally limited to personal injury and property damage caused by our employees at a customer’s desalination plant in proportion to the employee’s percentage of fault for the accident. Damages incurred for these indemnifications would be covered by our general liability insurance to the extent provided by the policy limitations. We have not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements is not material. Accordingly, we had no liabilities recorded for these agreements as of September 30, 2014 and December 31, 2013.
	In certain cases, we issue warranty and product performance guarantees to our customers for amounts ranging from 10% to 30% of the total sales agreement to endorse the execution of product delivery and the warranty of design work, fabrication, and operating performance. These guarantees, generally in the form of stand-by letters of credit or bank guarantees secured by stand-by letters of credit, typically remain in place for periods ranging up to 24 months and in some cases up to 59 months, and relate to the underlying product warranty period. The stand-by letters of credit are collateralized by restricted cash and our credit facility. Of the $5.0 million in outstanding stand-by letters of credit at September 30, 2014, $2.3 million was issued under the 2009 Agreement and $2.7 million was issued under the 2012 Agreement. The stand-by letters of credit outstanding at September 30, 2014 were collateralized by restricted cash of $5.1 million.
	Litigation
	Note 9 – Commitments and Contingencies, under the caption “Litigation” of our Annual Report on Form 10-K filed with the SEC on March 11, 2014, provides information on certain litigation in which we are involved. Unfavorable rulings, judgments, or settlement terms regarding these litigation matters could have a material adverse impact on our business, financial condition, results of operations, and cash flows. Although none of the litigation matters can be quantified with absolute certainty, we have established accruals covering exposure and relating to contingencies to the extent that they are reasonably estimable and probable based on available facts.
	See Note 4 – “Equity – Restricted Cash,” for a discussion of our August 2014 settlement of the litigation concerning the Pump Engineering, LLC acquisition.
	On September 10, 2014, the Company terminated the employment of Mr. Borja Sanchez-Blanco, Senior Vice President of Sales, for cause on the basis of breach of duty of trust and conduct leading to conflicts of interest. On October 3, 2014, Mr. Blanco filed a complaint with the labor commissioner in Madrid, Spain against the Company and its subsidiary Energy Recovery Iberia SL. Mr. Blanco alleges among other things, that he was terminated without cause. The complaint alleges wages due (salary and bonus) of approximately €567,000 and alleged stock option gains of €630,000, as a result of the alleged termination without cause. At this time, no reserve has been accrued as we have determined that an award to Mr. Blanco is not probable.

Fair Value Disclosures [Abstract]	'
Fair Value Disclosures [Text Block]	'
	Note 12 — Fair Value Measurements
	The authoritative guidance for measuring fair value provides a hierarchy that prioritizes the inputs to valuation techniques used in measuring fair value as follows:
	Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities;
	Level 2 — Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and
	Level 3 — Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions that market participants would use in pricing.
	The carrying values of cash and cash equivalents, restricted cash, accounts receivable, unbilled receivables, accounts payable, and other accrued expenses approximate fair value due to the short-term maturity of those instruments. For our investments in available-for-sale securities, if quoted prices in active markets for identical investments are not available to determine fair value (Level 1), then we use quoted prices for similar assets or inputs other than quoted prices that are observable either directly or indirectly (Level 2). The investments included in Level 2 consist primarily of certificates of deposits; commercial paper; and municipal, corporate, and agency obligations.
	The carrying amount of the contingent consideration arising from our acquisition of Pump Engineering, LLC was measured at fair value on a recurring basis using unobservable inputs in which little or no market activity existed (Level 3). The estimated fair value of the contingent consideration was determined based entirely on management’s assessment of the weighted probability of payment under various scenarios. See Note 4 – “Equity – Restricted Cash,” for a discussion of our August 2014 settlement of the litigation concerning this contingent consideration.
	The fair value of financial assets and liabilities measured on a recurring basis for the indicated periods was as follows (in thousands):

	Use of Estimates
	The preparation of condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires our management to make judgments, assumptions, and estimates that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Our more significant estimates and judgments that we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition; allowance for doubtful accounts; allowance for product warranty; valuation of stock options; valuation and impairment of goodwill, long-lived assets, and acquired intangible assets; useful lives for depreciation and amortization; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies, including contingent consideration. Actual results could differ materially from those estimates.
Basis of Accounting, Policy [Policy Text Block]	'
	Basis of Presentation
	The condensed consolidated financial statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.
	The accompanying condensed consolidated financial statements have been prepared by us, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. The December 31, 2013 condensed consolidated balance sheet was derived from audited financial statements, and may not include all disclosures required by U.S. GAAP; however, we believe that the disclosures are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2013 included in our Annual Report on Form 10-K filed with the SEC on March 11, 2014.
	In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.
Inventory, Policy [Policy Text Block]	'
	Change in Method of Accounting for Inventory Valuation
	Prior to January 1, 2014, inventories were stated at the lower of cost (using the weighted average cost method) or market. Effective January 1, 2014, with the final implementation of our new enterprise resource planning (“ERP”) system, we changed our method of accounting for inventories to the first-in, first-out (“FIFO”) method. We believe that the change is preferable, as the FIFO method better reflects the current value of inventories and provides more accurate matching of manufacturing costs and revenues. Due to the limited capabilities of our former ERP system, we determined that it was impracticable to retrospectively apply the FIFO costing method to prior periods. As such, prior period consolidated financial statements have not been retroactively adjusted. The cumulative effect of this change was not material.
New Accounting Pronouncements, Policy [Policy Text Block]	'
	Recent Accounting Pronouncements
	On May 28, 2014, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, Revenue from Contracts with Customers. The amendment requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period, which is January 1, 2017 for us. Early application is not permitted. ASU 2014-09 permits the use of either the retrospective or cumulative effect transition method. We are evaluating the effect that ASU 2014-09 will have on our consolidated financial statements and related disclosures. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.
