Following more than five years of planning and construction, the San Mateo Wastewater Treatment Plant, on the shoreline of San Francisco Bay, has undergone a $552 million upgrade and expansion, becoming the largest public works investment in the city’s history. The facility is now one of the most advanced and sustainable wastewater treatment plants in the nation. The comprehensive five-year project, carried out in three phases, has significantly increased the plant’s capacity to handle major storm events and prevent sewer system overflows that threaten both public health and San Francisco Bay.
