Water Quality

In the more than 100 years the City of San Diego has been delivering water to its citizens, we have never sold a drop of water deemed unsafe by any local, state or federal agency. That's a record we're proud of, and one we're determined to continue. At the left of this page is a link to current and past reports regarding the quality of your water.
