What’s in San Diego’s water?
The City of San Diego's Public Utilities Department supplies most of the region's largest city, and it imports the overwhelming majority of its water from the Colorado River and Northern California's State Water Project, supplemented by local reservoirs and desalinated seawater from nearby Carlsbad. All that imported supply gives San Diego tap water a hard, mineral rich character along with the disinfectant treatment used across Southern California. From coastal neighborhoods to inland canyons, residents notice spotty dishes, scale on fixtures, and dry skin and hair after showering. The minerals also build up inside water heaters and pipes, shortening appliance life throughout the home. A PurAgain system removes up to 99% of contaminants, giving San Diego families cleaner, softer, better tasting water no matter which part of the city they call home.
The only way to know exactly what’s in your San Diego water is to test it, and that in-home test is free.
