Urban water management plans.

Existing law, the Urban Water Management Planning Act, requires every public and private urban water supplier that directly or indirectly provides water for municipal purposes to prepare and adopt an urban water management plan. The act requires each urban water supplier to update its plan at least once every 5 years on or before December 31, in years ending in 5 and zero, and requires an urban water supplier to submit copies of its plan and copies of amendments or changes to the plan to certain entities, including the Department of Water Resources. This bill would authorize an urban water supplier to include within an urban water management plan certain energy-related information, including, but not limited to, an estimate of the amount of energy used to extract or divert water supplies. This bill would require the department to include in its guidance for the preparation of urban water management plans a methodology for the voluntary calculation or estimation of the energy intensity of urban water systems.
