West Yost provided design and construction management
services to expand the existing 14-Mile Slough Pump Station
(14-MSPS) by nearly 700%. This project represents one of the
largest trench-style wetwell pump stations in California. The
award-winning pump station upgrade increased reliable pumping
capacity from 3.75 mgd to 14 mgd, and with a buildout capacity of
22.5 mgd.
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 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 provided construction management and inspection
services for this $38 million water treatment plant improvements
project. The three-year construction management project expanded
the Jamieson Canyon WTP from 12 mgd average/16 mgd maximum to 20
mgd average/24 mgd maximum capacity. West Yost’s CM team included
construction management, resident engineering, inspections, and
administrative services, as well as support expertise in process
engineering, scheduling, and cost estimating.
West Yost provided planning, design, and construction management
services for the Linne Road Reservoir and Pump Station project.
The project consists of construction of a 7.2 MG, buried,
prestressed concrete reservoir, a 21 mgd booster pump station,
and installation of approximately two miles of 24 inch
transmission main.
The facilities are located within a park site adjacent to a
baseball field.The tank is buried and covered with tennis
courts. West Yost’s services included preparation of a
feasibility report that evaluated alternative site
configurations, hydraulic modeling, design, and services during
construction.
West Yost provided engineering design and construction management
services for a 2,100 gpm pump station (10A), 300 feet of 8-inch
pipeline and approximately 1,500 feet of 20-inch pipeline,
seismic improvements to a partially-buried 3 MG reservoir (10A),
and water distribution system interconnections.
West Yost is providing construction management for construction
of a new cast-in-place concrete structure adjacent to the
existing headworks while keeping the existing headworks
operational.
West Yost was recently selected to provide construction
management services for the City of Modesto’s $100 million Phase
2 Biological Nitrogen Removal/Tertiary Treatment Project. West
Yost has completed the constructability review of contract
documents. Phase 2 work will include construction of a new
advanced secondary treatment and tertiary treatment facilities
within the footprint of the existing secondary plant.
West Yost provided construction management/inspection under an
accelerated construction schedule for this 156 cfs storm water
pump station, which included trench style concrete wetwell,
mechanical “flexrake” trash rack, four propeller duty pumps with
low speed motors, and one low flow pump. Construction was
completed 10 weeks after breaking ground to provided the interim
stormwater pumping facilities needed to accept storm water.
West Yost provided planning, analysis, environmental review,
permitting, design, and construction management services for the
Dry Creek WWTP Levee Relocation. This project included the
hydrologic and hydraulic analyses of Dry Creek in the vicinity of
the WWTP. The project provides 100 year protection of the
wastewater storage ponds while enhancing the flow carrying
capacity of Dry Creek in an environmentally sensitive manner.
