Clean Water Program

The Clean Water Program is a comprehensive plan to upgrade the San Mateo Wastewater Treatment Plant, jointly owned by the Cities of San Mateo (75%) and Foster City/Estero Municipal Improvement District (25%), and San Mateo's wastewater collection system with advanced infrastructure that will provide reliable services for years to come.

Why Now?

• The current Wastewater Treatment Plant has components that are over 75 years old, and improvements to accommodate current and future operating requirements are needed.
• We are responding to the direction of our regulators requiring specific corrective actions, while planning for future regulations related to wet weather capacity and the quality of our effluent water.
• Improvements to the Wastewater Treatment Plant have added environmental benefits, including a cleaner San Francisco Bay, production of a new recycled water source, and alternative fuel sources.
