The Westside Pumping Plant Replacement Project includes replacement of existing EBMUD facilities and construction of new and replacement pipeline, as described below. The project will replace critical aging water distribution facilities that have reached the end of their useful lives to increase system reliability and operating efficiency, and to improve water quality operations.
Approximately 6,600 feet of new and replacement 12-inch discharge pipeline will be installed as part of this project in El Toyonal and La Encinal. Approximately 300 feet of new two-inch pipeline will be installed in Madera Lane from Vallecito Lane to 6 Madera Lane.
EBMUD plans to replace the existing 0.5-million-gallon-per-day (MGD) Encinal Pumping Plant (PP) and 0.3-MGD Westside PP with a new 0.6-MGD Westside PP. The new Westside PP will be constructed at 4 Madera Lane, the site of the existing Encinal PP. The Encinal PP will be demolished. At 20 El Rincon, both the existing Westside PP and the existing 0.2-million-gallon (MG) redwood Encinal Reservoir will be demolished. The Encinal Reservoir will be replaced with a new Encinal Regulator, to be housed within the new Westside PP.
Active construction work hours are 8:30 a.m. to 5:00 p.m., Monday through Friday. Trucks and personnel can arrive at work sites for reporting, minor tasks, and meetings after 7:00 a.m. Pipeline construction will take place before the facilities construction and demolition.
Pipeline construction is anticipated to start in spring 2020 and will take approximately 12 months to complete. Construction and demolition of the facilities is anticipated to start in summer 2021 and last approximately two years.
Partial and/or full street closures will be required during portions of the construction. Traffic control plans will be submitted to the City of Orinda. Standard construction environmental and safety practices applicable to all EBMUD construction projects have been incorporated into the project. These standard practices minimize impacts to the public resulting from EBMUD construction projects.
Some road segments within the immediate vicinity of facilities or pipeline work may be closed to all vehicular traffic except emergency service vehicles from 8:30 a.m. to 5:00 p.m., Monday through Friday. Detour access will be maintained where possible.
Construction of replacement pipelines will take place with the existing pipelines still in service. Short shutdowns and minimal interruptions in water service will occur when new pipelines are connected to existing pipelines and when service laterals are transferred from the existing to the new pipelines. Crews will notify you, in person or with a door hanger, regarding any planned water service interruption to your property. After a service interruption, there may be air in the pipes that may loosen particles in your home plumbing. Close your toilet water supply valves, and then run water from your front hose bib, bathtub and/or cold water faucets for 1-3 minutes which will dispel any air or loosened particles from your household pipes. If any water quality issues remain after flushing, please call us.
The asphalt paving applied daily is temporary and is designed to provide a safe road surface during construction. Final paving occurs after pipeline work is completed. It may take up to 30 days or longer before final paving is completed. Watch a video on how EBMUD paves streets following pipe replacements.
