Item 2.01                      Completion of Acquisition or Disposition of Assets.

On December 21, 2009, Energy Recovery, Inc. (“ERI”) completed its acquisition of Pump Engineering LLC (“PEI”), under a previously announced Agreement and Plan of Merger (the “Merger Agreement”), dated December 2, 2009, with PEI, CFE Acquisition Corporation, a wholly-owned subsidiary of ERI (“Merger Sub”), Roy Radakovich in his capacity as the Company Representative, and U.S. Bank National Association, in its capacity as the Escrow Agent.  Pursuant to the Merger Agreement, PEI was merged with and into Merger Sub (the “Merger”), with Merger Sub which was named Pump Engineering, Inc., a Delaware corporation, being the surviving entity, as a wholly owned subsidiary of ERI.

Pursuant to the Merger Agreement, ERI paid the owners of PEI (i) an initial cash payment of Fourteen Million Five Hundred Thousand Dollars ($14,500,000) and (ii) One Million (1,000,000) shares of ERI’s Common Stock.  ERI also deposited (i) Three Million Five Hundred Thousand Dollars ($3,500,000) in an escrow account which will be paid to the owners of PEI upon the achievement of certain milestones, and (ii) Two Million Dollars ($2,000,000) in an second escrow account, which amount, less those amounts paid to ERI pursuant to the indemnification provisions of the Merger Agreement, will be paid to the owners of PEI eighteen (18) months after the closing of the Merger.

The foregoing description of certain terms of the Merger Agreement does not purport to be complete, and is qualified in its entirety by reference to the full text of such agreement previously filed and incorporated by reference in this report pursuant to Item 9.01(d) below.  The representations and warranties of each party set forth in the Merger Agreement have been made solely for the benefit of the other parties to the Merger Agreement. In addition, such representations and warranties (i) have been qualified by disclosures made to the other parties in connection with the Merger Agreement, (ii) at closing, must only be true and correct subject to the standards contained therein, which may differ from what may be viewed as material by investors and (iii) were made only as of the date of the Merger Agreement, the date the Merger may be consummated, or such other date as is specified in the Merger Agreement.


Item 3.02                      Unregistered Sales of Equity Securities

At the effective time of the Merger on December 21, 2009, ERI issued One Million (1,000,000) shares of ERI's Common Stock in a transaction exempt from registration under the Securities Act of 1933, as amended (the “Act”), by reason of Section 4(2) of the Act and/or Regulation D promulgated under the Act.
