Loop Canal Cleaning

Each winter, the District conducts a full cleaning of 21 miles of the Canal loop from Clyde to the Martinez Reservoir (see map below.) The annual cleaning is performed during the winter months when water usage is low and customer impacts can be minimized. The cleaning, which typically takes three months, is safely managed by District crews by utilizing equipment to push the accumulated sediment from the sides and bottom of the Canal. The sediment is then removed with a crane for final disposal.

District crews began draining the loop portion of the Contra Costa Canal mid-December 2018 in anticipation of regular annual cleaning. Rolling closures along the Contra Costa Canal Trail will be in effect starting at the beginning of January 2019 as the District performs its annual cleaning of the aqueduct.

The work hours for this project will be 7 a.m. to 4 p.m. Monday-Friday. If you have any concerns or questions about this work, please call 925-688-8010 during normal business hours.
