Capital Improvement Projects (CIP)
The Belle Haven I Sewer Rehabilitation Project was awarded to Precision Engineering of San Francisco, CA for the amount of $2,069,930.00.The project involved the replacement and rehabilitation of District sewer mains. The Belle Haven I area project included approximately 10,900 feet of sanitary sewer main lines located between Ivy Drive, Willow Road, and Pierce Road within the City of Menlo Park. Sewer mains were replaced using both open trench and pipe bursting methods and were rehabbed using the structural cured-in-place-pipe (CIPP) liner method.
The Belle Haven II Sewer Project area consists of the replacement and rehabilitation of approximately 18,000 linear feet (3.4 miles) of 6 inch to 15-inch sanitary sewer mains. The Belle Haven II project is the second phase of what is anticipated to be a three phase project.
The Belle Haven II area is approximately 18,000 feet of sanitary sewer mains located between the Bayshore Freeway, Bayfront Expressway, and Willow Road within the City of Menlo Park. The project will involve the replacement and rehabilitation of the sewer mains with the standard open trench method in areas where the pipeline needs replacement and trenchless methods using a structural cured-in-place-pipe (CIPP) liner and pipe bursting in areas where the pipeline can be rehabilitated. The engineer’s estimated cost for construction is $3,600,000.00.
The Belle Haven III Sewer Project is one of four areas of work in this year’s CIP and the area consists of the replacement and rehabilitation of over two miles of 6- to 24-inch diameter sanitary sewer mains. The existing sewer mains were identified as needing upgrades as part of the updated Capital Improvement Master Plan, and the Belle Haven III project is the third phase a three-phase project.
The second area is located between Willow Road, Hamilton Avenue, and the Bayshore Freeway within the City of Menlo Park. The third is located on Oak Avenue, Vine Street, Campo Bello Lane and Alameda De Las Pulgas in unincorporated San Mateo County and the City of Menlo Park. The fourth area is on Maple Avenue and El Camino Real in the Town of Atherton. The fourth area is on Cascade Drive and Gabarda Way in the City of Menlo Park and the Town of Portola Valley respectively.
Three project involve the replacement and rehabilitation of the sewer mains. The District will use a standard open trench method in most areas where the pipeline needs replacement and a trenchless method called pipe-bursting in some areas where open trenching is not practical. Another trenchless method called CIPP can also be used in areas where pipe rehabilitation, which involves relining the existing pipes instead of replacing them, is feasible. The bid was awarded to Precision Engineering with a bid of $4.8M.
The Sausal Vista Pump Station feasibility study determined it was feasible to eliminate the Corte Madera Pump Station located along Portola Road near the Corte Madera Creek crossing and rebuild the Sausal Vista Pump Station located along Georgia Lane to accommodate the combined flows. The project abandons the existing Corte Madera pump station and redirects the flows with new gravity sewers to a new deeper Sausal Vista pump station. The project also included a new force main from the new Sausal Vista pump station to the existing force main along Portola Road connecting at the intersection of Portola Road and Georgia Lane. Phase 2 reconstructed the Sausal Vista Pump Station. This phase also included the redirection of the flows to the new gravity sewer and force main constructed in Phase 1. The engineer’s estimated cost for construction for Phase 2 was $1,200,000.00. Phase 1 of the project was completed September 2016 and completion of Phase 2 is expected soon.
