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.

This winter, District crews began draining the loop portion of the Contra Costa Canal mid-December 2018. The cleaning is complete, and the loop canal will be refilled and fully operational by mid-April 2019.
