What SAWS publishes
15–20
grains per gallon
That is the typical hardness in the water SAWS supplies, in its own words. Very hard — and the reason almost every house in Bexar County has something worth fixing.
Why this matters
You already know something’s off with your water
Most people don’t call us because they read a water quality report. They call because of one of these four things.
Spots on everything
Glasses come out of the dishwasher cloudy. Shower doors film over days after you clean them. That's dissolved calcium left behind when hard water evaporates.
Skin and hair feel wrong
Soap doesn't rinse off properly in hard water, so it sits on your skin. Dry, itchy skin and flat, brittle hair are the most common complaints we hear.
Your water heater is dying early
Scale builds up on the heating element and insulates it, so the heater burns more energy to do less. Hard water can take years off its life.
It tastes like a pool
Chlorine is added to keep city water safe on the way to your house. It does its job — it just doesn't taste good in coffee.
Our systems
Built for the water you actually have
City water and well water are different problems. A 2,000 sq ft home and a 5,000 sq ft home are different problems. We size the system to your house, not to a price list.
Most popularStandard Whole-Home Softener + Filtration
48,000 grains. Soft water and chlorine filtration in one tank.
Handles the two problems almost every home around here has at once: hard water that scales your pipes and water heater, and chlorine that makes water taste like a swimming pool and dries out skin and hair. One tank, one valve, installed free.
Best for: Most 3–4 bedroom homes on city water

Best sellerHW800 AlkaPro Tankless RO
800 gallons a day, 7 stages, no bulky tank under your sink.
Tankless reverse osmosis that filters down to 0.0001 microns — fine enough to take out lead and other heavy metals, dissolved solids, chlorine and common contaminants. Because it's tankless, you get water on demand and your under-sink cabinet back.
Best for: Anyone who wants better drinking and cooking water
Details and specs
Dual Tank — Well Water
Built for iron, sulfur and that rotten-egg smell.
Well water is a different problem from city water. This system pairs a softening tank with a Katalox Light tank to pull out iron, manganese and hydrogen sulfide — the cause of the smell, the orange staining and the metallic taste. Two ProValves, one per tank.
Best for: Homes on a private well

Treats every drop entering your house — showers, laundry, dishwasher, ice maker. This is what fixes hard water, scale and chlorine.

Four steps, and the first two are free
We’d rather tell you that you don’t need a system than sell you the wrong one. That’s a strange sales pitch, and it’s also why people send us their neighbors.

Why this market is different
San Antonio has some of the hardest water in Texas.
SAWS publishes the number itself: the typical hardness in the water it supplies runs from 15 to 20 grains per gallon. That is very hard by any scale in the trade, and it is the utility’s own figure rather than something a salesperson told you.
It comes from the rock. Edwards and Trinity aquifer water sits in limestone before it reaches you and dissolves calcium carbonate the whole way, which is what ends up on your glassware, in your water heater and on every fixture in the house.
That is a solvable problem, and it is the same equipment the big brands sell without the theatre: the right system for your water, an honest price, free installation, and a warranty that lasts as long as you own the system.

Questions
The things people ask us
Anything we haven’t covered, just call. We don’t use a phone tree.
How hard is the water in San Antonio?
Hard enough that almost every home around San Antonio shows it — white spots on glassware, crust around faucets, soap that won't lather, and a water heater working harder than it should. Exactly how hard depends on which reservoir your city draws from, which is why we size the system to your home rather than quoting from a map.
What does a whole-home system actually cost?
It depends on your water and your house — the size of the system, whether you're on city water or a well, and where the equipment has to go. Call or fill out the form, tell us about your home and your water, and we'll give you a real, complete installed price.
Is installation really free?
Yes. There is no installation charge on our systems. It's included, and it's done by our own installers rather than subcontractors.
What does the lifetime warranty cover?
The system itself, for as long as you own it. That's the whole point of the name — we'd rather sell you equipment that lasts than sell you a replacement in six years.
Do I need a softener, a filter, or both?
Different problems. A softener removes the calcium and magnesium that cause scale and dry skin. A filter removes chlorine, taste and odour. Most San Antonio homes have both problems, which is why our whole-home systems do both in one unit. If you're on a well, iron and sulfur are usually the bigger issue and that needs a different build entirely.
How long does an installation take?
A typical whole-home install is a half day. An under-sink reverse osmosis system is usually a couple of hours. We work around your schedule and clean up after ourselves.
