Graywater systems continue to be allowed in the City of Escondido. Simple laundry-to-landscape set ups do not require a permit, though they must comply with the standards found in the 2013 California Plumbing Code. All other graywater systems require a permit through the City's Building Division. Contact the Building Division at 760-839-4647 for more information.

Graywater is untreated wastewater that does not include any toilet discharge, unhealthy bodily wastes, or manufacturing wastes. It can be wastewater from bathtubs, showers, bathroom washbasins, and clothes washing machines.
