Why San Diego's water matters for price

The City of San Diego's 2025 drinking water report shows treatment-plant average hardness of 13.8 to 14.2 grains per gallon. (Source: City of San Diego 2025 Annual Drinking Water Quality Report) Harder water and bigger households need more softening capacity, which drives price (HomeGuide).

San Diego's figure is a range of treatment-plant averages, not a reading for your home. Which plant serves you, and your own plumbing, affect what comes out of your tap, so get a test before you buy.

FAQ: water softener cost in San Diego

How hard is San Diego's water?

The City of San Diego's 2025 drinking water report shows treatment-plant average hardness of 13.8 to 14.2 grains per gallon.

Will a water softener make my drinking water taste better?

Not necessarily. A softener trades hardness minerals like calcium and magnesium for other substances, often sodium, so it targets scale rather than taste. For drinking water, an under-sink reverse osmosis system is the usual choice, and TDS reduction is a required claim for RO systems certified to NSF/ANSI 58.
