Mountain View Interceptor Force Trunk Rehabilitation

The City of Mountain View rehabilitated the severely deteriorated interceptor force trunk main that runs from the Shoreline Sewer Pump Station through a driving range/golf course to the Palo Alto Wastewater Treatment Plant. The project rehabilitated 1,083 feet of the 42-inch interceptor force trunk main, replaced the existing flanged outlet manhole adjacent to the pump station and constructed an additional downstream manhole adjacent to Michael’s Restaurant. BKF provided the civil engineering design services for the project, including project administration and coordination, design development, and preparation of construction documents.
