The Sunnyvale Cleanwater Program Phase 2 project will include rehabilitation of existing facilities and construction of new facilities throughout the city’s existing wastewater treatment plant. Phase 2 includes rehabilitating the existing secondary and tertiary treatment facilities, constructing new secondary and biosolids handling facilities, and reconstructing the support facilities necessary to operate the plant.
