The Clean Water Program is a comprehensive plan to upgrade the aging wastewater collection and treatment system with advanced infrastructure that will provide reliable services for years to come to several communities in the San Francisco Bay area, including the cities of San Mateo, Foster City, and portions of Hillsborough, Belmont, Crystal Springs County Sanitation District, and the County of San Mateo. Many of these improvements are either in design or construction. Some of the construction has been completed.
