Map of project location.Beginning Monday, August 12, City contractors will be installing a new sewer pipe on El Camino Real between Warren Road and State Street. This is part of City-wide efforts to increase the capacity of the sewer system and help prevent overflows that occur during storms. Work will take place between 9am and 3pm, and will last approximately two weeks. On El Camino Real, one lane in each direction will be kept open during this work. Street parking along portions of Warren Road and State Street will be temporarily affected during work hours only, and “No Parking” signs will be posted in these areas in advance of the work.

Site Preparations for WWTP Upgrades Begin on August 19

Rendering of new Waste Water Treatment Facility

Phase 1 of the San Mateo Wastewater Treatment Plant upgrades will begin on August 19. The Clean Water Program is the most significant upgrade to the City’s sewer infrastructure in its modern history. Once completed, the WWTP will produce high-quality treated water that will meet new water quality regulations and benefit the City’s residents, future generations, the local environment, and the San Francisco Bay Community.

Phase 1 includes construction site preparations. During this time, informational signs will be posted, and the contractor will arrive onsite. They will set up their construction trailer and begin demolition of existing equipment and facilities to clear space for new elements. Preparations for upcoming construction (including excavation, installation of perimeter shoring, and dewatering; electrical upgrades and stormwater management improvements) will also begin. Site safety and security measures (such as pathway closures and parking restrictions) will be put in to place during this time, as will traffic, dust, and noise control measures.

Phase 1 is expected to conclude in early Fall 2020. Phase 2 is expected to begin in late spring 2020, and includes foundation building activities. Additional information about the project will be provided to the community prior to Phase 2. The entire project is expected to take approximately 5 years.
