Save Water


The Municipal Water District of Orange County (MWDOC) is committed to protecting and preserving Orange County water supplies now and long into the future. Providing clean, safe, reliable water to Orange County residents and businesses is a top priority. To ensure that the water supply we have will continue to sustain us for decades to come, we must all do our part.


Water Use Efficiency

Thanks to water-smart behavior changes and advanced technologies, Southern California uses nearly 40 percent less water today than we were using three decades ago.
