Water treatment in New Braunfels, Texas
New Braunfels is a springs town, and the same limestone that feeds Comal Springs makes the tap water very hard. We test, install, and service water softeners, whole-home filtration, and reverse osmosis across New Braunfels, starting with a free water test that shows you exactly what's in your water.

Figures are typical values, not your house's number. NBU blends river water with aquifer wells, and state samples vary noticeably from one part of the system to another.
What fits your house
Match the symptom to the system
Most New Braunfels homes need one or two of these, not all three. The water test tells us which, and the recommendation is only ever sized to what your water shows.
New Braunfels has been one of the fastest-growing cities in the country, and if your home is in one of the newer master-planned communities, odds are it includes a softener loop, so installs there are usually quick and land at the low end of the price range. Older homes near downtown may need the loop added, and we quote that plainly before any work starts.
Questions
Questions we get about New Braunfels water
Is New Braunfels tap water safe to drink?
Yes. NBU's water is TCEQ-regulated, tested constantly, rated Superior by the state, and reported publicly every year. The things people notice day to day, like scale, spots, and chlorine taste, are quality-of-life issues, not safety issues. We treat water to make it nicer to live with, and we'll tell you exactly what our test finds.
How hard is New Braunfels water?
Very hard by the Water Quality Association's scale, which starts "very hard" at 10.5 grains per gallon. State samples of NBU's treated water mostly run 16 to 17 grains per gallon, and they vary by entry point, so your neighborhood's number can differ from across town. The free test gives you your house's number.
Where does New Braunfels water come from?
Most of it is Guadalupe River water treated at NBU's Gruene Road plant, blended with wells in the Edwards and Trinity aquifers, plus purchased water as needed. A blend that includes river water and limestone groundwater arrives hard either way, and the mix shifts through the year.
Does New Braunfels use chlorine or chloramine?
NBU's report lists its residual as total chlorine, and local reporting says the system uses chloramine, which is chlorine bonded with ammonia. The difference matters because chloramine needs catalytic carbon to filter well. Part of the free test is confirming what's actually in your water before we spec anything.
My house is in a new development. Do I still need a softener?
New pipes don't change the water inside them, so a new build in Veramendi or Mayfair gets the same very hard water as a century-old house near the Plaza. The good news is that many newer builds include a softener loop, a plumbing stub made for a softener, which keeps installation quick and toward the low end of the range.
Do you cover all of New Braunfels?
Yes. We serve New Braunfels and the surrounding Comal County communities. Some addresses around the edges of town are on other utilities, like Crystal Clear WSC or Canyon Lake Water Service, and the free test works the same no matter whose water arrives at your tap.
