San Diego County Water Authority Rancho Penasquitos Pressure Control/Hydroelectric Facility

Scope of services included facilitation of the construction management and inspection services for the Rancho Penasquitos Pressure Control & Hydroelectric Facility; an integral component of the San Diego County Water Authority’s $1 Billion Dollar Emergency Storage Project. This facility was designed to be used in conjunction with the Water Authority’s Twin Oaks Valley Diversion Structure to raise the hydraulic grade line above topographic control features, and to control flow and water pressure for deliveries of untreated water to Aqueduct connections, the Olivenhain Reservoir, and San Vicente Pipeline. This $23 Million Dollar project received the 2006 American Society of Civil Engineers outstanding project award as part of their Civil Engineering Project Awards program.

Construction included the installation of one 4.3 mega-watt Francis Turbine Generator unit housed within a 3,000 square foot reinforced concrete and masonry building. Other work involved the installation of 3,100 linear feet of 96-inch diameter polyurethane lined welded steel pipe, installation of four 42-inch diameter electric motor operated, horizontal sleeve type control valves and the integration of the facility into the Water Authority aqueduct SCADA system.
