Downtown Sewer Replacement Project
City of Yuba City, California

West Yost designed the relocation, replacement, and/or rehabilitation of existing sewers in the City’s downtown residential area to address structural deficiencies, maintenance issues, and system reliability. The existing sewers were installed nearly 100 years ago and could not be cleaned or maintained due to pipe fragility and lack of access. The challenges of replacing these backyard sewers included access, public outreach, homeowner coordination, design approach, and construction methods for rerouting sewer laterals.

Project

14-Mile Slough Pump Station
City of Stockton, California

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.
