The Central Reservoir Replacement Project (Project) involves replacing East Bay Municipal Utility District’s (EBMUD; District) 154-million gallon (MG) open-cut reservoir with three new 14-MG prestressed concrete tanks situated within the northern portion of the existing reservoir basin. The Project will improve water service reliability, water quality operations, and long-term maintenance by replacing an aging facility and embankment dam with an optimally sized facility that matches the elevations of the other existing reservoirs in the Central Pressure Zone. The higher reservoir elevation will improve operational flexibility by allowing Central Reservoir to support future planned and unplanned outages of other facilities, improve reliability by providing buffer storage to the west-of-hills distribution system, and improve water quality operations by right-sizing the storage amount and increasing the operating range of Central Reservoir.
