How Hard Is Katy Water, Exactly?
Katy is served by the City of Katy plus dozens of MUDs, all drawing groundwater from the Gulf Coast Aquifer. Hardness varies by district — here's what the published water quality reports show:
| Water Provider | Hardness | Grains/Gallon | Typical Areas |
|---|---|---|---|
| City of Katy | 150-180 ppm | 9-10.5 GPG | Old Town, Downtown Katy |
| Fort Bend County MUDs | 165-210 ppm | 9.5-12 GPG | Cinco Ranch, Seven Meadows, Grand Lakes |
| Harris County MUDs | 160-195 ppm | 9.5-11.5 GPG | Elyson, Cane Island |
Why this matters for sizing
Anything over 120 ppm (7 GPG) is officially "hard" — Katy runs 150-210 ppm everywhere. A softener that's undersized for your hardness and household regenerates too often, burns through salt, and wears out early. That's why we size from your district's reported hardness instead of installing one one-size-fits-all unit. Full details on how hardness affects your home are in our Houston hard water guide.
Softener Sizing for Katy Homes
Based on Katy hardness (9-12 GPG) and typical household water usage:

| 3-4 bath, 3-5 people | ~250-400 gal/day | 1.5-2.0 cu.ft. / 48,000-64,000 grain | Good + upsize — $3,390 |
| 4+ bath, 5+ people, or taste concerns | 400+ gal/day | 2.0 cu.ft. mixed bed (resin + carbon) | Better — $3,850 |

New Build in Elyson, Cane Island, or Cross Creek Ranch?
Your builder likely roughed in a loop
Most new Katy homes include a water softener loop in the garage — two capped pipes waiting for equipment. We mount, connect, and program the system on the loop in about 2 hours. No exploratory plumbing, no drywall work.
Tankless water heaters need soft water
Tankless units — standard in new Katy construction — scale up fast at 150-210 ppm. Many manufacturers require treated water to keep the warranty intact. Softening from day one protects the heater, the dishwasher, and every fixture in the house.
