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 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 schedule

Prior to the initiation of pipe installation, a large valve was installed on Bancroft Way in January 2018 at Ellsworth Street in Berkeley to connect the new transmission lines to the existing distribution system. Exploratory work to gather information about existing infrastructure in Ellsworth St. and Stuart St. will take place intermittently leading up to major project work. 

Starting in summer 2019 for approximately 6 months, EBMUD crews will begin preliminary work to relocate existing pipes and install new valves at 5 locations along the project alignment:

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

Work hours are 7:30 a.m. to 5:30 p.m., Monday through Friday. Expect some temporary lane closures and loss of street parking to support construction.

Construction of the Wildcat Pipeline in Berkeley is anticipated to begin in early 2021 and last for about two years.
