City of South San Francisco Sewer Improvement Project

NV5 is providing Construction Management services to the City of South San Francisco for the improvement of the sewer system and construction of new pump stations under Phase II of the City’s Wet Weather Program. The program’s goal is to enhance the treatment of effluent and storm water to prevent pollution of San Francisco Bay. The City of South San Francisco is relatively flat and close to the Bay, thereby affected by tidal action, and occasionally has need to forcibly pump storm water. In addition, the City’s system can act as a combined storm/sanitary system. The east side of Highway 101, where most of the vibrant growth of South San Francisco’s biotechnology industry is located, is being upgraded to provide additional capacity and more flexible management of flows to the nearby wastewater treatment plant.

The project includes construction of a new pump station and the addition of bypass capability to the system. The storm drainage is 36-inch pipeline and the sanitary capability is being increased from 12-inch to 15-inch using pipebursting method. An additional project upsizes the storm drain system in the industrial area of the City and includes the replacement and addition of manholes and inlets.

NV5 has served as Construction Manager throughout the pre-bid phase of the work, reviewing design documents, scopes of work, schedules, and final project refinements. During construction our Resident Engineer and Inspectors oversee the activities of the contractor and our Office Engineer maintains project correspondence.
