Phase 2 of the upgrade and expansion of a wastewater treatment plant on Detroit Drive in San Mateo has begun and will reportedly include eight-and-a-half months of pile driving to secure the expanded facility at its location near Seal Point in the Shoreview neighborhood, according to the city.
The pile driving will occur during the daytime only in two stages about five months apart, the city said. Noise reductions and control measures will be in place, it added.
The five-year-long plant upgrade is the largest component of the $1 billion, decade-long Clean Water Program, which will replace the aging wastewater collection and treatment system with advanced infrastructure that serves San Mateo, Foster City, and parts of Hillsborough, Belmont, Crystal Springs County Sanitation District and the county. The new system aims to achieve compliance with strict regional regulations for wastewater collection and treatment. During heavy rains, the existing system is overwhelmed, which can lead to sanitary sewer overflows and the partial treatment of wastewater at the plant and poses health concerns for the community and environment.
On Thursday, June 11 from 6-8 p.m., a Virtual Community Meeting will take place so members of the community can hear details and ask project planners questions.
“We encourage the residents of San Mateo to follow the progress being made on these much-needed improvements for our city,” said Brad Underwood, San Mateo’s Public Works director. “Maintaining this infrastructure and ensuring that the system continues to meet current and future operating requirements are essential to the health and well-being of our community.”
