San Diego County

Better water, every tap, across San Diego County.

San Diego Water Filtration assesses your water first, explains what is in it in plain language, then installs the right filtration or softening system for your home. Local service, straight answers, and support long after the install.

Three things people notice first

Most water problems in San Diego County come down to one of these three. Each one is treated differently, which is why the assessment comes first.

Hard water across the county

Treated water from San Diego's three city plants averaged about 14 grains per gallon of hardness in 2025. East County's Helix Water District reported an average of 12.0 grains per gallon.

Chloramine in the tap

San Diego, Escondido, Oceanside, Vista and East County utilities all disinfect with chloramine, a combination of chlorine and ammonia. It is added on purpose so a disinfectant stays in the water all the way to your tap.

Water from far away

Most of the county's water is imported from the Colorado River and Northern California through the State Water Project. In 2025, Helix Water District's supply was 51 percent Colorado River, 29 percent State Water Project and 20 percent local.

Chlorine, chloramine and PFAS

And the stuff you cannot taste.

Chlorine

You can usually taste it.

Chloramine

Most people cannot.

PFAS

Nobody can.

Which is why the assessment starts with what your utility publishes about San Diego County water, not a guess.

Questions we get asked

If yours is not here, send it with your assessment request. There is no wrong question about your own water.

We call and go through your water with you. Then you get the system we would put in and the exact price. The assessment is free.

The number we put in writing is the number. If something in your house would change it, you hear about it before any work starts.

Wherever the water enters the house, usually a basement, a utility room or a garage.

Enough floor for the tanks plus room to open the cabinet lid and get to the bypass.

Top up the cabinet when it runs low. That is the whole routine, and the setup notes cover it.

Yes. A private supply changes through the year, so it gets sized differently from a municipal one. We handle both.
