The water system for a home or other property is connected to a City water main through a water lateral service line via a water meter. The property owner is responsible for the maintenance of any portion of the water system from the meter. A diagram showing the division between what is the City's responsibility and what is the responsibility of the property owner can be found here.

- Water Hardness - Typically, drinking water in San Diego averages about 16 grains per gallon (gr/gal) or 276 parts per million (ppm), and depending upon water demand and area of the City you live can range from 16 to 18 gr/gal or 272 to 284 ppm. More details are available in the annual Drinking Water Quality Reports.
- GIS Information (Maps and Records) - The City's Development Services Department has records showing when your water line was installed and can provide a map showing where your water line connects to the City's water main. You can schedule an appointment to review the records by calling 619-446-5300. However, the City does not have diagrams or other information regarding where water lines are located on your property. For that information, you may want to contact a licensed plumber.
