Dingee Backbone Map

EBMUD has completed replacement of a 12,000-foot segment of the aging Dingee Backbone Pipeline, a primary transmission pipeline that delivers water to 18,000 customers in the central Oakland Hills. Several related projects in the area including the replacement of three 54-inch diameter aqueducts at EBMUD's Claremont Center and replacement of water transmission lines under Tunnel Road, Roble Road, and Marie Way and Erba Path were also recently completed.

This pipeline replacement construction was necessary to reduce service disruptions and maintenance costs associated with leaking and deteriorating pipelines that were originally installed in the 1920's.

EBMUD completed a Mitigated Negative Declaration (MND) to assess the impacts of the project and identify mitigation measures. The draft MND and addendum are available in the Published Studies and Other Resources section below.

Glen Echo Creek Concrete Spill

On April 8, 2015, cellular concrete was inadvertently spilled into a half mile stretch of Glen Echo Creek during filling activities to prevent sink holes on the abandoned Dingee pipeline in the Harbord Drive, Truitt Lane, Clarewood Lane and Clarewood Drive area in Oakland. Following the spill, EBMUD collaborated with state and local resource agencies to quickly clean the area and is continuing to restore the area.

EBMUD has agreed to pay just over $426,000 to the California Department of Fish and Wildlife and the San Francisco Bay Regional Water Quality Control Board for penalties and damages to natural resources related to the April 2015 spill. We are committed to continued habitat protection and monitoring to assure the creek’s long-term health. To learn about the restoration efforts, click here.
