Berkeley - Wildcat Pipeline

West Of Hills New Alignment Map

West Of Hills New Alignment Map

EBMUD is planning to install a new 48-inch transmission pipeline in Berkeley on Stuart Street between Benvenue Avenue and on Ellsworth Street and along Ellsworth Street from Stuart Street to Bancroft Avenue in order to improve and expand the water system in an area that serves customers from Berkeley to Crockett. 

Initial community outreach took place in 2013 when the Draft Environmental Impact Report was published. EBMUD has evaluated the environmental implications of the new alignment. An addendum to the environmental document has been prepared and is available under the "Published studies and other resources" section of the West of Hills Northern Pipelines page.

Workplan and schedule

In January 2018, EBMUD completed the first stage of the Wildcat Pipeline Improvement Project with the installation of a large valve on Bancroft Way at Ellsworth Street in Berkeley that will eventually connect the new Wildcat Pipeline to the existing distribution system.

Exploratory work to gather information about existing infrastructure along the project alignment will take place intermittently leading up to major project work. 

Starting in summer 2019 for approximately 6.5 months, EBMUD crews will relocate smaller distribution water pipelines and install new valves at 5 locations along the project alignment to make room for the Wildcat Pipeline:

- Ellsworth St. at Durant Ave. for approximately 6 weeks
- Ellsworth St. between Dwight Way and Blake St. for approximately 6 weeks
- Ellsworth St. at Carleton St. for approximately 1 week 
- Ellsworth St. at Stuart St. for approximately 3 weeks
- Stuart St. between Telegraph Ave. and College Ave. for approximately 10 weeks.

Installation of the new Wildcat Pipeline will follow preliminary work in fall 2020 and will last through summer 2021.

Typical project work hours are 8 a.m. to 7 p.m., Monday through Friday with some extended work hours and night work at heavily trafficked intersections or for critical tie-in work to the existing distribution system. If extended or overnight work hours are required, the community will be notified in advance.
