West Yost provided an award-winning project for Placer County
that provided a cost conscious solution to the rehabilitation of
the Auburn Ravine Lift Station (ARLS).
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 preliminary and final design of one of the
largest cured-in-place-pipe (CIPP) projects in the U.S., to
rehabilitate approximately 44,700 feet of sewer using an
innovative liner material (iPlus®). The trunk line is 42-inches
to 60-inches in diameter and runs under major streets,
residential backyards, creeks, a freeway, through protected
wetlands, and near many homes, schools, and businesses.
Approximately 3,000 feet of the Franklin Trunk is also included
in the project.
West Yost prepared a Sanitary Sewer Master Plan for the
Clean Water Services District (District). The project
included evaluating the system, expanding and updating the
collection system hydraulic model, and ranking problem areas
according to severity of surcharging under three development
conditions in order to differentiate between near-term and
long-term projects.
