The purpose of the Sunnyvale Cleanwater Program (Program) is to upgrade the City’s Water Pollution Control Plant (Plant) through a series of 34 long-term projects that will replace or repair facilities to ensure reliable cleaning of wastewater. These improvements generate additional benefits such as enhanced energy efficiency, increased production of recycled water, and improved resilience related to climate change, all while incorporating cutting-edge wastewater treatment technology to streamline operations. At an estimated cost of $1.4 billion, this program is the largest, most complex capital endeavor the City has ever undertaken. With many improvement projects in the design phase or under construction, a cleaner, more sustainable future awaits Sunnyvale residents and businesses.
