Sacramento River Pump Station
Princeton-Codora-Glenn/Provident Irrigation Districts
Wood Rodgers provided Design and Construction Management services for the Princeton-Codora-Glenn and Provident Irrigation Districts (Districts) Anadromous Fish Screen Project. The project, designed by Wood Rodgers, consolidated three existing diversion facilities, owned and operated by the Districts, into one 600cfs diversion facility. The project presented significant challenges in that two large cofferdams within and adjacent to the Sacramento River were required to dewater the area of the four intake bay sand four flow closure structures. The project required the placement of over 3,000 cubic feet of concrete. Significant coordination with Caltrans, the Central Valley Flood Protection Board, and the US Army Corps of Engineers was required to bore and jack four 9 foot diameter casing pipes beneath the Sacramento River levee and State Highway 45, which is located on the levee crown.
As part of this project, Wood Rodgers designed a new pumping facility to replace three existing pump stations owned by the Districts. Along with a 600 cfs pumping station, submerged, self-cleaning fish screening system, Wood Rodgers designed 2,000 lineal foot conveyance system consisting of a stilling basin, trapezoidal canal, and flume. The conveyance system reconnected the new pumping facility with existing District infrastructure relating to the decommissioned pumping plants.
