Water Softeners & Filtration in Round Rock
Spotty glasses, crusted showerheads, towels that feel like cardboard, a water heater that dies young — that's Round Rock water. The city measures roughly 14–16 grains per gallon, and the exact chemistry depends on your source: Lake Georgetown surface water, Edwards Aquifer wells, Chisholm Trail SUD groundwater out east, or a private well. Treatment works — but only when it's sized for the water you actually have.
What Hard Water Costs You Here
- Water heaters: sediment and scale cut tank life from 12–15 years to 8–10 — and Round Rock's housing stock is full of builder-grade units hitting that wall right now
- Energy bills: ⅛" of scale on the element cuts efficiency ~12%
- Fixtures: etched glass, scaled aerators, drip-calcified showerheads
- Skin & hair: the soap-film feeling is mineral residue — worse with SUD and well water than with city water
Which Water System Are You Even On?
This is the question most plumbers skip, and it's why one-size softener installs disappoint:
- City of Round Rock (most of the city): Lake Georgetown surface water blended with Edwards Aquifer well water and, since 2020, Lake Travis water via the Brushy Creek Regional Utility Authority. Hard, but treated and consistent.
- Chisholm Trail SUD (east Round Rock, Chisholm Valley, parts toward Hutto): groundwater — typically harder and with a different mineral profile than the city's supply.
- Private wells (rural edges and acreage toward the county line): can run very hard with sediment; often need filtration before softening.

Our Install Process
- Free on-site hardness test — measured at your kitchen tap, not guessed from a city average.
- Size to the household — grain capacity matched to hardness × people × bathrooms. Oversized wastes salt; undersized never keeps up.
- Clean installation — loop install or main-line cut-in, bypass valve, code-compliant drain routing.
- Demand-initiated regeneration — metered cycles, not dumb timers. Most Round Rock households run 6–8 lbs of salt a month.

💡 Well owners: rural Williamson County wells often need sediment filtration — and sometimes iron treatment — before softening. We test for all of it in one visit and quote what your water demands, not a package.
