Accounting Policies [Abstract]  
Basis of Presentation The Condensed Consolidated Financial Statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries. 
All intercompany accounts and transactions have been eliminated in consolidation.
The accompanying Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the
Securities and Exchange Commission (the “SEC”).  Certain information and footnote disclosures normally included in the financial statements
prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules
and regulations.  The December 31, 2025 Condensed Consolidated Balance Sheet was derived from audited financial statements and may
not include all disclosures required by GAAP; however, the Company believes that the disclosures are adequate to make the information
presented not misleading.
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.
Reclassifications Certain prior period amounts have been reclassified in certain notes to the Condensed Consolidated Financial Statements to conform
to the current period presentation.
Use of Estimates The preparation of Condensed Consolidated Financial Statements, in conformity with GAAP, requires the Company’s management to
make judgments, assumptions and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and
accompanying notes.
The accounting policies that reflect the Company’s significant estimates and judgments and that the Company believes are the most
critical to aid in fully understanding and evaluating its reported financial results are revenue recognition; stock-based compensation expense;
equipment useful life and valuation; goodwill valuation and impairment; inventory valuation and allowances, deferred taxes and valuation
allowances on deferred tax assets; and evaluation and measurement of contingencies. Those estimates could change, and as a result,
actual results could differ materially from those estimates.
The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a
revision of the carrying value of its assets or liabilities as of August 5, 2026, the date of issuance of this Quarterly Report on Form 10-Q. 
These estimates may change, as new events occur and additional information is obtained.  Actual results could differ materially from these
estimates under different assumptions or conditions.  The Company undertakes no obligation to publicly update these estimates for any
reason after the date of this Quarterly Report on Form 10-Q, except as required by law.
Recently Adopted and Issued Accounting Pronouncements Not Yet Adopted In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2025-05, Measurement of
Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”).  ASU 2025-05 provides a practical expedient for measuring
expected credit losses on current accounts receivables and contract assets by assuming that conditions at the balance sheet date remain
unchanged over the life of the asset. The Company adopted ASU 2025-05 on January 1, 2026 and the adoption did not have a material
impact on the Company’s results of operations, cash flows, or financial condition.
There have been no issued accounting pronouncements that have not yet been adopted during the six months ended June 30, 2026
that apply to the Company other than the pronouncements disclosed in Note 1, “Description of Business and Significant Accounting Policies -
Recently Issued Accounting Pronouncements Not Yet Adopted,” of the Notes to Consolidated Financial Statements included in Item 8,
“Financial Statements and Supplementary Data,” of the 2025 Annual Report.
Income (Loss) Per Share Net income (loss) for the reported period is divided by the weighted average number of basic and diluted common shares outstanding
during the reported period to calculate the basic and diluted income (loss) per share, respectively.  Outstanding stock options to purchase
common shares, unvested restricted stock units (“RSUs”), and unvested performance restricted stock units (“PRSUs”) are collectively
referred to as “equity awards.”
Basic income (loss) per share is computed using the weighted average number of common shares outstanding during the period.
Diluted income (loss) per share is computed using the weighted average number of common and potentially dilutive shares
outstanding during the period, using the treasury stock method.  Any anti-dilutive effect of equity awards outstanding is not
included in the computation of diluted income (loss) per share.
Litigation The Company considers all claims, if any, on a quarterly basis and, based on known facts, assesses whether potential losses
are considered reasonably possible, probable and estimable.  Based upon this assessment, the Company then evaluates disclosure
requirements and whether to accrue for such claims in its consolidated financial statements.  The Company records a provision for a liability
when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.  These provisions are
reviewed at least quarterly and are adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other
information and events pertaining to a particular case.
Income Taxes The Company’s interim period tax benefit from income taxes is determined using an estimate of its annual effective tax rate, adjusted
for discrete items, if any, that arise during the periodEach quarter, the Company updates its estimate of the annual effective tax rate, and if
the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period.  The Company’s quarterly tax
provision and estimate of its annual effective tax rate are subject to variation due to several factors, including variability in accurately
predicting its pre-tax income or loss and the mix of jurisdictions to which they relate, the applicability of special tax regimes, and changes in
how the Company does business.
