Mid-Peninsula Station Tanks 119 and 120

This project includes the installation of two new water storage tanks located within a residential neighborhood in the hills of San Carlos. The new 400,000 gallon tanks will be completed in parallel and are similar in design to a DN tank without the post-tensioning element. This project also includes the installation of new ductile iron pipe that will be connected to the existing distribution system. The sites have significant site constraints for construction work and laydown areas, due to their locations within an existing, well developed residential neighborhood. The Station 119 site design includes a retaining wall along the hillside at the back of the property to create an access area for the contractor’s equipment, during the construction of the new tank. The project requires monitoring of mitigation measures established in the IS/MND document and the coordination of special inspections.
