Santa Monica tap water meets every drinking water standard, but it carries a disinfectant taste and a mineral content that changes with the season. An under-sink reverse osmosis system gives you clean, great-tasting water for drinking, cooking, coffee and ice, and ends the bottled water runs. Praz Pure Water has installed and serviced drinking water systems for Westside homes and businesses for over 20 years.
What is in Santa Monica tap water?
Santa Monica runs its own water utility and publishes its test results every year. The city pumps most of its water from local wells, treats it at the Arcadia Water Treatment Plant with reverse osmosis, and blends in imported water. Here is the most recent data:
| Measure | Santa Monica (2025) | What it means for drinking |
|---|---|---|
| Disinfectant (chlorine / chloramines) | 1.8 ppm citywide average Up to 3.5 ppm | Safe, but it is the taste and smell most people notice |
| Dissolved solids, city well water | 177 ppm average Range 138 – 207 ppm | Minerals and salts that affect taste |
| Hardness, city well water | 103 ppm average (about 6 grains per gallon) | Moderately hard; leaves film in kettles and coffee machines |
| Hardness, imported water | 140 – 234 ppm average (about 8 – 14 gpg) | Hard to very hard when it is in the blend |
| Where it comes from | Up to 75% local wells, the rest imported | The blend, and the taste, change through the year |

Praz under-sink drinking water systems, each with its own dedicated faucet at the sink.
Up to 75% of Santa Monica’s water comes from local groundwater wells; the rest is imported through the Metropolitan Water District from the Colorado River and Northern California. None of this makes the water unsafe. It does explain why your tap can taste different from one month to the next, and why so many Santa Monica households still buy bottled water. A reverse osmosis system at the kitchen sink removes the disinfectant taste and most of the dissolved minerals, whatever the blend is that day.
Why Santa Monica homes filter their drinking water
- Taste and smell. The disinfectant that keeps city water safe is what you taste in a glass of tap water, in coffee and in ice.
- Bottled water. Cases and five-gallon jugs cost more every year, take up space and leave a pile of plastic. A system under the sink replaces them.
- Coffee, tea and cooking. Filtered water makes better coffee and tea and keeps mineral film out of kettles and espresso machines.
- Peace of mind. Reverse osmosis reduces a wide range of dissolved contaminants, so you know what your family is drinking.

Frequently asked questions
Is Santa Monica tap water safe to drink?
Yes. The City of Santa Monica tests its water throughout the year and it meets state and federal drinking water standards. People filter it for taste, for the disinfectant smell and for peace of mind, not because it is unsafe.
Why does Santa Monica tap water taste the way it does?
Two reasons. The water is disinfected, and the city’s 2025 report shows a citywide average of 1.8 ppm of chlorine and chloramines, which is what most people taste and smell. The supply is also a blend: up to 75% comes from local wells and the rest is imported, so the mineral content changes through the year.
What does a reverse osmosis system remove?
Reverse osmosis pushes water through a membrane with extremely small pores. It removes the disinfectant taste and odor, most dissolved minerals and salts, and a wide range of other dissolved contaminants. The result is clean, neutral-tasting water for drinking, cooking, coffee and ice.
Where does the system go?
Under the kitchen sink, with its own dedicated faucet next to your main one. We can also connect it to a refrigerator or ice maker. Our packages can add instant hot water and a chiller in the same cabinet.
Can I rent a drinking water system instead of buying one?
Yes. Our water filtration rental for homes and offices starts from $28 a month and includes installation and filter changes.
How much does a drinking water system cost in Santa Monica?
It depends on the system and the options you choose. Every package includes professional installation, standard materials and the full manufacturer warranty. We confirm your exact price on site after the free water test, before any work begins.
How long does installation take?
An under-sink reverse osmosis system usually takes about one to two hours. We check the cabinet space and the connections during the free water test.
Do you serve the areas around Santa Monica?
Yes. We serve Santa Monica, Brentwood, Pacific Palisades, Venice and West Los Angeles, as well as the wider Los Angeles area.
