Contra Costa Loop Canal Cleaning

Annual Cleaning of the Contra Costa Loop Canal
Empty heading

Each winter, CCWD 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. 

CCWD crews skillfully and safely manage the cleaning process, utilizing specialized equipment to clear accumulated sediment from both the sides and bottom of the canal. The extracted sediment is efficiently removed using a crane for proper 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 for a visual representation of the cleaning route.
