About San Diego Water Systems by My Home Water System

San Diego Water Systems helps San Diego homeowners compare water treatment options and request a written quote from one qualified local company. The request form names that company before you submit.

San Diego Water Systems is run by My Home Water System, operated by Aidren LLC. We are not a water utility and are not affiliated with City of San Diego Public Utilities.

Where do the water figures come from?

Every figure is copied from the utility's own published report or web page, with its period and a link. We do not test water and do not estimate figures. Sources were last checked October 27, 2026.
