Explore how Upper Water ensures a reliable water supply through strategic planning, water management, and innovative partnerships.
Water Supply & Management
Upper Water balances local groundwater with imported sources, ensuring a sustainable supply. With 80% groundwater and 20% imported water, we manage water resources to secure long-term availability.
Water Quality Standards
Water quality is a top priority. Upper Water collaborates with local and state authorities to operate over 30 treatment facilities to ensure all water supplied meets or exceeds strict federal standards.
Our Water Partners
Our partnerships with local water retailers and the Metropolitan Water District of Southern California help us deliver high-quality water while managing supply and conservation efforts across the region.
Strategic Water Plans
Upper Water’s long-term water strategies, including the Urban Water Management Plan (UWMP), Integrated Resources Plan (IRP), and Water Use Efficiency Plan (WUEP), address water challenges through sustainable practices and forward-thinking policies.
