Water Loss Control
California Water Code Section 10608.34 requires the State Water Board to develop water loss performance standards for urban retail water suppliers between January 2019 and July 2020. The State Water Board is required to evaluate the life-cycle cost of achieving these standards.
Executive Orders B-37-16 and B-40-17 direct the State Water Board and Department of Water Resources (DWR) to minimize water waste through system leaks.
