Document Description
EBMUD's existing 0.24-million-gallon Dos Osos Reservoir will be replaced with new dual 0.12 MG, steel-bolted reservoirs on EBMUD owned watershed property approx 70 ft higher in elevation, 300 ft southwest of the existing Dos Osos Reservoir site in the city of Orinda. A new, 12-in, inlet-outlet pipeline will be constructed to connect the existing water distribution system to the new dual reservoirs and will be located in an approx 800-ft long access road that will be constructed for permanent access from Los Norrabos to the new dual reservoirs. EBMUD's existing Dos Osos Pumping Plant, located at 263 El Toyonal, Orinda, is a 0.3-million gallons per day pumping plant that will be rehabilitated at the same capacity; however, the Dos Osos Pumping Plant will be upgraded with pump units that can pump to a higher total dynamic head to serve dual Osos Reservoirs. Upon construction completion and successful testing of the new facilities, the existing Dos Osos Reservoir will be demolished.
