Supervisor Andersen joined Orinda City Manager David Biggs, Orinda Mayor Denis Fay, East Bay Municipal Utility District (EBMUD) General Manager Clifford Chan, Board Member Marguerite Young, and Community Affairs representative Kathryn Horn to learn about EBMUD’s upcoming Orinda Water Treatment Plant Disinfection Improvements Project. She also toured the plant, which was built in 1935. It is the largest of six EBMUD water treatment plants and serves over 800,000 customers. 90% of the water filtered and treated there comes from the Pardee Reservoir at the base of the Sierra Nevada.
