West Yost provided planning, design, and construction
management for the Ophir Road Pump Station. This pump
station constructed about a mile upstream and 210 feet
above the Auburn Tunnel outlet, allows Placer County Water
Agency (PCWA) to pump water from the tunnel for municipal
and agricultural use. It is designed to pump 332 cfs of
water through three distinct pump stations, housing 11 vertical
turbine pumps ranging in size from 200- to 600-hp.
West Yost designed a new 4-MG potable water storage tank and
booster pump station for the City of Davis. Project
components included a prestressed concrete tank, pump station
building, chlorination facilities, perimeter fencing,
landscaping, offsite utilities, and SCADA. Related issues
included locating a potential cell tower on the tank site and
providing for future delivery of treated surface water to the
water storage tank.
West Yost is assisting the Woodland-Davis Clean Water Agency in
an Owner’s Representative capacity for the program and
Design-Build-Operate (DBO) procurement contract management, water
rights acquisition, public outreach, environmental permitting and
preliminary design of a new regional surface water supply
project. The project will consist of a diversion intake facility
on the Sacramento River, a conveyance pipeline from the intake to
a new 40-mgd capacity water treatment plant, and a pipeline
distribution system to the participants’ service areas.
Construction on the new facilities is expected to begin in 2013
and be completed by 2016.
West Yost provided hydraulic analysis, predesign, design, and
construction management and inspection for the
award-winning, Stoneridge Water Storage Facility. The
project consists of a 2.9 MG prestressed concrete,
partially buried, tank and associated inlet/outlet piping,
control valves, drains, and site improvements.
West Yost developed a dynamic hydraulic model for the City
of Corvallis’ water distribution system. The new model
incorporates GIS, geocodes customer billing data to allocate
water demand, and was calibrated using an innovative and highly
effective tracer analysis.
