DENVER, CO, Mar. 1, 2011 -- CH2M HILL (www.ch2mhill.com), a global full-service consulting, design, construction, and operations firm, is pleased to announce that the Freeport Regional Water Authority Intake Facilities Project located in Sacramento, Calif., has won the American Society of Civil Engineers (ASCE) California Region's Geotechnical Project of the Year award. The Freeport Regional Water Authority is a Joint Powers Authority of the East Bay Municipal Utility District (EBMUD) and the Sacramento County Water Agency (SCWA). CH2M HILL provided planning studies and analysis for the full Project and final design services for the Sacramento River Intake and Pump Station facilities.

ASCE awards program recognizes the commendable achievements and remarkable accomplishments of the civil engineering profession. All of the Region 9 project and people awards will be presented at the ASCE Region 9 Fifth Annual California 2011 Infrastructure Symposium and Awards Dinner, being held March 9 at the Hyatt Regency in Sacramento.

The Freeport Regional Water Authority Intake Facilities Project is a $121M regional raw water supply project on the Sacramento River with 185 million gallons per day total design capacity, serving both EBMUD and SCWA. The project includes diverting water from the Sacramento River at Freeport Bend and pumping to the SCWA and EBMUD delivery points via an 18 mile transmission pipeline system. The intake includes state-of-the-art vertical plate fish screens meeting all National Oceanic and Atmospheric Administration Fisheries and California Department of Fish and Game requirements. A first-of-its-kind innovative sediment management system was included in the pump station forebay/wetwell chambers to provide important operational advantages.

Key geotechnical aspects of the intake structure, pump station, pipeline, and ancillary structures include in-river development of a cofferdam and drilled pier foundation consisting of over 200 36-inch cased piers, construction of a 80-foot deep levee cutoff slurry wall, installation of anchored sheetpile bulkhead training walls, and completion of two 102-inch microtunnel crossings of Interstate 5, Freeport Boulevard, railroad tracks, and a canal. Design of these elements was completed by CH2M HILL's in-house Geotechnical Engineers with data collection services provided by AGS Inc. of Oakland, CA.
