Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the "Securities Act"), this Registration Statement shall also cover any additional shares of common stock, par value $0.001 per share (the "Common Stock") which become issuable under the Energy Recovery, Inc. 2020 Incentive Plan (the "2020 Plan") by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without the Registrant's receipt of consideration that results in an increase in the number of outstanding shares of Registrant's Common Stock.
(2)
Estimated in accordance with Rule 457(c) and Rule 457(h)(1) under the Securities Act solely for the purpose of calculating the registration fee for shares reserved for future issuance under the 2020 Plan. The computation is based on the average of the high and low prices of the Registrant's Common Stock as reported on The Nasdaq Global Select Market for March 30, 2021.
(3)
As described in the Explanatory Note in this Registration Statement, on July 16, 2020, the stockholders of the Registrant approved the 2020 Plan and, in connection therewith, no further awards will be made under the Energy Recovery, Inc. 2016 Incentive Plan (the "2016 Plan") and the Energy Recovery, Inc. 2008 Equity Incentive Plan (the "2008 Plan").  Of the 10,849,450 shares of the Registrant's common stock being registered under the 2020 Plan on this Registration Statement, up to 1,394,727 shares that were previously available for issuance but not issued or subject to outstanding awards under the 2016 Plan now may be issued under the 2020 Plan.
(4)
Pursuant to Rule 457(p) under the Securities Act, the total registration fee for the shares being registered hereby is reduced by the filing fee of $1,424.15 previously paid by the Registrant in connection with the registration of shares of common stock on the Form S-8 Registration Statement for the "2016 Plan (File No. 333-212707) filed with the Securities and Exchange Commission (the "Commission") on July 27, 2016 (the "2016 Registration Statement"), which shares are contemporaneously with the filing of this Registration Statement being deregistered from the 2016 Registration Statement by Post-Effective Amendment No. 1 to the 2016 Registration Statement.
EXPLANATORY NOTE
This Registration Statement on Form S-8 (this "Registration Statement") is being filed for the purpose of registering shares of the Registrant's common stock, par value $0.001 per share (the "Common Stock"), that may be issued to participants under the Energy Recovery, Inc. 2020 Incentive Plan (the "2020 Plan").
The maximum number of shares of Common Stock reserved and available for issuance under the 2020 Plan includes (i) 4,500,000 shares of Common Stock, (ii) 4,954,723 shares of Common Stock subject to outstanding stock awards granted under the Energy Recovery, Inc. 2016 Incentive Plan (the "2016 Plan") and the 2008 Equity Incentive Plan that may become available for issuance under the 2020 Plan, as such awards expire, terminate or are otherwise surrendered, cancelled or forfeited, and (iii) 1,394,727 shares of Common Stock available for issuance but not subject to outstanding awards under the 2016 Plan, which were absorbed by the 2020 Plan as of May 5, 2020, the effective date of the 2020 Plan.  The 1,394,727 shares of Common Stock that remained available under the 2016 Plan were previously registered with the Commission on the Registration Statement on Form S-8 (File No. 333-212707) (the "2016 Registration Statement""). Such shares are now covered by this Registration Statement in connection with the 2020 Plan. A post-effective amendment to the Form S-8 Registration Statement for the 2016 Plan is being filed contemporaneously with this Registration Statement to deregister such shares under the 2016 Registration Statement.

Item 4. Description of Securities.
Not applicable.
Item 5. Interests of Named Experts and Counsel.
Not applicable.
Item 6. Indemnification of Directors and Officers.
The Registrant's amended and restated certificate of incorporation provides that the Registrant may indemnify to the fullest extent permitted by Delaware law any person made or threatened to be made a party to an action or proceeding, whether criminal, civil, administrative or investigative, by reason of the fact that he or she was a director or officer of the Registrant or serves or served at any other enterprise as a director or officer at the request of the Registrant. Further, the Registrant's amended and restated certificate of incorporation contains provisions that limit the personal liability of the Registrant's directors for monetary damages to the fullest extent permitted by Delaware law.
In addition, as permitted by Section 145 of the Delaware General Corporation Law, the amended and restated bylaws of the Registrant provide that:
•
The Registrant shall indemnify its directors and officers for serving the Registrant in those capacities or for serving other business enterprises at the Registrant's request, to the fullest extent permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Registrant and, with respect to any criminal proceeding, had no reasonable cause to believe such person's conduct was unlawful.
•
The Registrant may, in its discretion, indemnify employees and agents in those circumstances where indemnification is not required by law.
•
The Registrant is required to advance expenses, as incurred, to its directors and officers in connection with defending a proceeding, except that such director or officer shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification.
•
The Registrant will not be obligated pursuant to the bylaws to indemnify a person with respect to proceedings initiated by that person, except with respect to proceedings authorized by the registrant's board of directors or brought to enforce a right to indemnification.
•
The rights conferred in the bylaws are not exclusive, and the registrant is authorized to enter into indemnification agreements with its directors, officers, employees and agents and to obtain insurance to indemnify such persons.
•
The Registrant may not retroactively amend the bylaw provisions to reduce its indemnification obligations to directors, officers, employees and agents.
The Registrant also maintains directors and officers insurance to insure such persons against certain liabilities.

Item 9. Undertakings.
A.
The undersigned Registrant hereby undertakes:
1.
To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement:
i.
To include any prospectus required by Section 10(a)(3) of the Securities Act;
ii.
To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement;
iii.
To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;
provided, however,
that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the Registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
2.
That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
3.
To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
B.
The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
C.
Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.
