What’s in Bonita’s water?

Set in the green Sweetwater Valley, Bonita is served by two agencies, with the Sweetwater Authority covering the western portion and the Otay Water District serving the east. Sweetwater blends locally sourced reservoir and desalinated groundwater with imported supply, while Otay relies chiefly on imported Colorado River and State Water Project water. Either way, homeowners in this semi-rural community typically face hard-water scale on fixtures, spotty dishes, and dry skin after showering. On Bonita's larger lots, the mineral buildup is also tough on irrigation systems and water heaters. A PurAgain system removes up to 99% of contaminants at the source, protecting your home's plumbing and delivering softer, fresher water no matter which district you fall under.

The only way to know exactly what’s in your Bonita water is to test it, and that in-home test is free.
