Wastewater Treatment Plant Expansion
City of Corning, California

West Yost provided planning, design engineering and full-time onsite construction management services for the expansion of the City’s wastewater treatment plant (WWTP).

The City’s WWTP was expanded to accommodate growth within the City’s service area. Improvements included a new headworks and influent flow monitoring upgrade, improvements to improve oxidation ditch aeration capacity, conversion of two center-feed secondary clarifiers to peripheral-feed, construction of a third secondary clarifier, disinfection control and monitoring improvements, upgrades to the administration building, and installation of a new standby generator.
