Description

This project consisted of constructing a pumping plant on the Delta Mendota Canal (DMC) to connect it to the California Aqueduct (CA), thereby allowing flexibility in the state’s water conveyance system. The project included four major segments: the DMC Pump station, a 69 kV electrical switchyard, yard piping, and the CA turnout structure.

The DMC pump station consisted of a 3,000 cubic yard cast-in-place concrete structure with six intakes and two outlets for reverse flow operations, and a pre-engineered metal building to contain the four 112.5 cfs 1,000 hp pumps, electrical switchgear, HVAC and control systems.

The 69 kV switchyard takes the incoming power feed from the Tracy substation and converts it to 5 kV for the pumps. SCCI self-performed the Electrical scope of work.

Yard piping consisted of installing two parallel 108-in RCP lines crossing underneath a 500 kV overhead line.
