Acorn Reservoir Replacement Project

Acorn ReservoirAs part of EBMUD’s infrastructure renewal program, the Acorn Reservoir located at the end of Eagle Ridge Drive in Blackhawk will be replaced. The existing 1.2-million gallon (MG) welded-steel reservoir is oversized for the community it serves and has reached the end of its useful life. EBMUD will build two smaller tanks with the combined capacity of 1 million gallons. Replacing one large tank with two will allow EBMUD to take one tank out of service during low-demand periods. This will reduce maintenance costs and improve water quality.

Workplan and schedule

Replacement Tanks at Acorn ReservoirEBMUD will grade the area next to the existing reservoir, build a retaining wall and build one of the replacement reservoirs before removing the existing reservoir. Once the new reservoir is complete and in service, EBMUD will demolish the old reservoir and build the second reservoir in its place. Construction for this project will begin in September 2015 and is expected to be completed by April 2018. During the first stage of this project residents can expect to hear and see hauling trucks and equipment required for grading. Allowable work hours for this project are Monday through Friday from 7 a.m. to 6 p.m.
