The Municipal Water District of Orange County (MWDOC) develops, implements, and evaluates water use efficiency programs that significantly improve water supply reliability for Orange County. An integral component of our overall water supply portfolio, water use efficiency is our least expensive water source, providing multiple benefits to all water users. In addition to securing a cost effective, reliable source of water supply, other benefits of water use efficiency include runoff reduction, pollution prevention, and energy savings.

Available MWDOC water use efficiency programs include educational classes, performance reporting, water use surveys, and a variety of consumer incentives for indoor and outdoor water-efficient devices for residents and businesses throughout Orange County. Through an innovative, multi-agency approach, Orange County saves more than 18.5 billion gallons of water each year through our award-winning programs.
