As part of EBMUD’s Water Treatment and Transmission Improvements Program (WTTIP), EBMUD is upgrading and replacing existing facilities and constructing new facilities at the Orinda Water Treatment Plant (WTP), located at 190 Camino Pablo in the City of Orinda, California. Built in 1935, Orinda WTP is the heart of the EBMUD water distribution system, delivering water to more than 800,000 customers every day, including customers in the City of Orinda.
The Orinda WTP Disinfection Improvements Project (Project) will improve current water treatment processes by adding ultraviolet (UV) disinfection and a chlorine contact basin. Adding these disinfection improvements will reduce the formation of disinfection byproducts which form when chlorine reacts with naturally-occurring organic matter in water. The Project will provide reliable water treatment infrastructure that meets long-term operational needs and will continue to meet drinking water and environmental regulations to achieve EBMUD’s internal long-term water quality goals. The Project includes demolition of an existing maintenance building and construction of a new disinfection facility comprised of a new above-ground two-story maintenance and UV electrical (MAUVE) building with a below-grade UV structure and a below-grade chlorine contact basin (CCB), two electrical buildings, a standby generator, pipelines and vaults, and other supporting facilities. The MAUVE building with UV structure and the CCB would be adjacent and fully integrated facilities. Maintenance activities and associated uses previously housed in the existing maintenance building that will be demolished will be incorporated into the Project disinfection facility and grounds maintenance building with associated parking at the Orinda WTP site. The Project will also remove vegetation, install landscaping, replace existing and install new security fencing, and restore the site following construction.
Construction is expected to occur over a four and a half-year period from 2021-2025.
The Project is a modification of the disinfection improvements that were analyzed in EBMUD’s WTTIP Environmental Impact Report (EIR), which was certified in 2006. EBMUD is preparing a Supplemental EIR (SEIR) for the Project.
