Annual Cleaning of the Contra Costa Loop Canal Empty heading
Each winter, the District conducts a full cleaning of 21 miles of the Contra Costa Loop Canal from Clyde to the Martinez Reservoir. The annual cleaning is performed during the winter months when water usage is low and customer impacts can be minimized.
The cleaning 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.
The work typically begins at the Naval Weapons Station and proceeds along the Loop Canal through Clyde, Concord, Walnut Creek, Pleasant Hill, and Martinez. See the map below.
