The San Diego office of CH2M Hill Inc. has been awarded a contract of approximately $76.7 million to design and construct a new advanced water treatment plant and conveyance system at Marine Corps Base Camp Pendleton.

A U.S. Defense Department statement said work includes building a new potable water line with pump stations, a treatment facility and reservoir. The contract contains one option and one planned modification which, if exercised, would increase the cumulative contract value to approximately $80.7 million.

Work will be performed in Oceanside and is expected to be completed by January 2016. Naval Facilities Engineering Command Southwest in San Diego received nine proposals for the project via the Navy’s e-commerce website, the statement said.

Colorado-based CH2M Hill has 120 U.S. offices, including one in downtown San Diego. It provides engineering and construction services for government and private-sector projects, according to its website.
