San Clemente water report

San Clemente Water Quality: What's Really in Your Tap Water

Most of San Clemente is served by the city's own water utility, which blends imported Colorado River and State Water Project water from the Metropolitan Water District with water treated at Irvine Ranch Water District's Baker plant. Talega is served by Santa Margarita Water District, and parts of north San Clemente by South Coast Water District. The water meets state and federal standards, but it's hard, high in dissolved minerals, and EWG lists 15 contaminants above its stricter health guidelines.

Sources: EWG Tap Water Database, City of San Clemente (PWS CA3010036), 25 contaminants detected and 15 above EWG guidelines, 2013 to 2024 data; and the City of San Clemente 2024 Water Quality Report covering 2023 (hardness 160 mg/L average for MWD water and 297 mg/L for Baker plant water; TDS 394 and 612 ppm; chlorine disinfection). All results were below state and federal legal limits; EWG health guidelines are stricter, health-based goals. Contaminants marked for the RO faucet are reduced in your drinking and cooking water at the kitchen sink. Homes in Talega and parts of north San Clemente are served by other districts, so levels may differ.

Softening and soap savings

Hard Water Savings Calculator for San Clemente Households

Hard water quietly costs you money on energy, appliances, fixtures, plumbing and soap, and bottled water adds up fast. Here's what an average San Clemente household on hard water can expect to save with our complete system, based on independent studies.

Pick your household size to update the estimates.

Lower Water Heater Bills

$100/year
The research

Battelle: tank water heaters lose about 4% efficiency for every 5 grains of hardness. Soft water also lets you wash in cold water.

Longer-Lasting Appliances

$90/year
The research

Water heaters, dishwashers and washing machines last longer without scale. In Battelle tests, tankless heaters failed from scale in 1.6 years of use on 26 gpg water.

Clear Faucets and Showerheads

$50/year
The research

Battelle: showerheads on hard water lost 75% of their flow in under 18 months of use.

Fewer Plumbing Repairs

$60/year
The research

Less scale inside pipes, valves and toilet parts means fewer repair calls and descaling jobs.

Half the Soap and Detergent

$150/year
The research

WQRF study: soft water cut laundry detergent by 50% and dishwasher detergent by 50% or more in very hard water.

No More Bottled Water

$250/year
The research

Americans drink 47.3 gallons of bottled water per person each year. Your included 8-stage RO faucet replaces it with purified water from the tap.

What a San Clemente Home Spends vs. Saves, Year by Year

The blue line is everything you spend: the $3,399 system plus salt and RO filters every year. The green bars are what you save. Once the bars pass the line, the system has paid for itself.

Saved by year 20
$14,000
Spent, incl. upkeep

Money in your pocket
$7,601
Pays for itself
Year 6

Tap any year on the chart to see its numbers. Upkeep uses about $70 a year in softener salt for a 3 to 4 person home and about $80 a year in RO filters.

How we estimate this: averages for a household on about 20 gpg water, before price increases. Energy uses Battelle's finding of about 4% water heater efficiency loss per 5 gpg plus cold-water washing. Appliance and fixture figures spread replacement costs over shorter lifespans on hard water. Soap figures use WQRF's 50% detergent reduction for laundry and dishes. Bottled water uses 47.3 gallons per person per year at about $1.50 per gallon for bulk cases, replaced by the included reverse osmosis faucet. Figures are gross savings and do not include softener salt or RO filter replacement costs. Your actual savings depend on your home, water use, appliances and local rates.

San Clemente FAQs

San Clemente Water Questions, Answered Locally

Is San Clemente water hard?

Yes. The city's 2024 Water Quality Report shows imported Metropolitan Water District water averaging 160 mg/L of hardness, about 9.4 grains per gallon, and water from the Baker treatment plant averaging 297 mg/L, about 17 grains per gallon. That's hard to very hard, and your free test shows the level at your tap.

Where does San Clemente's water come from?

The City of San Clemente blends imported surface water from the Metropolitan Water District with water from Irvine Ranch Water District's Baker Water Treatment Plant, which it has received since 2017. The city's local groundwater plant was offline for rehabilitation in 2023. Talega is served by Santa Margarita Water District, and parts of north San Clemente by South Coast Water District.

Does San Clemente water have chlorine or chloramine?

The city's report says chlorine is added at the source of supply. Catalytic carbon removes chlorine at every tap and also handles chloramine, which some neighboring water systems use.

What contaminants are in San Clemente tap water?

EWG's Tap Water Database lists 15 contaminants above its health guidelines for the City of San Clemente, including arsenic, chromium-6, nitrate, uranium and disinfection byproducts like TTHMs and haloacetic acids. All were below legal limits, but EWG's guidelines are stricter health-based goals.

Why does my water leave white spots?

San Clemente's water carries 394 to 612 ppm of dissolved solids depending on the source, plus hardness. Those minerals dry into spots and film on glass, shower doors and fixtures. A softener stops the scale, and RO removes most dissolved solids from your drinking water.

I live in Talega or Forster Ranch. Can I install a softener with my HOA?

Usually, yes. Most systems install in the garage at the main water line, out of sight. If your HOA has rules about drains or equipment, we'll work within them, and a salt-free conditioner with no drain line is an option.

Do you serve Dana Point and San Juan Capistrano?

Yes. We serve all of San Clemente, plus Dana Point, Capistrano Beach, San Juan Capistrano, Rancho Mission Viejo and Ladera Ranch, and down the coast to Oceanside.

What does water treatment cost for a San Clemente home?

Our Mixed Bed Water Softener with Catalytic Carbon + 8-Stage Reverse Osmosis is $3,399 installed during our 40% off offer, down from $5,665, or from $60 a month with financing on approved credit. Your exact price is confirmed in writing after your free water test.
