How New Braunfels Compares
New Braunfels's water is 107% harder than the national average of 138 PPM. It ranks #72 out of 1000 cities in our database (harder than 93% of US cities we track). Within Texas, it ranks #4 of 76 cities (51% above the state average of 189 PPM). Among mid-size cities (100k-200k), New Braunfels ranks #10 of 189 for hardness. At this hardness level, water heaters run an estimated 52% less efficiently due to scale insulation, and major water-using appliances typically last 4 years less than the national average lifespan.
What New Braunfels's Water Means for Your Home
Hardness: 285 PPM - Treatment Recommended
New Braunfels has some extremely hard water. At 285 PPM (16.7 grains per gallon), your tap is loaded with mineral content carried in from the watershed geology. Here's the thing: it's perfectly safe to drink. The minerals won't hurt you. But they will hurt your wallet. That adds up. Hard water at 285 PPM increases household costs through scale-coated water heaters that use more energy, extra soap and detergent, and appliances that wear out faster. Most New Braunfels homeowners don't realize it until the plumber shows up. That's 51% harder than the Texas average.
Contaminants & Safety
Disinfection byproducts are the notable finding here. New Braunfels's water has TTHMs at 45.9 ppb and HAA5 at 18.2 ppb — both within legal limits, but the EWG health guidelines are far stricter. These byproducts form when chlorine reacts with organic matter during treatment. A whole-house activated carbon filter reduces both chlorine and its byproducts. Want the full picture? Request your utility's annual Consumer Confidence Report.
What's in the Treatment Process
New Braunfels's surface water supply requires heavy chlorination to stay safe — but that creates a tradeoff. The treatment process generates disinfection byproducts: TTHMs at 45.9 ppb (57% of the legal limit, but 306x the EWG guideline) and HAA5 at 18.2 ppb (30% of the legal limit, but 182x the EWG guideline). These are within legal limits, but the EWG sets much tighter thresholds based on cancer-risk research. A whole-house activated carbon filter reduces both chlorine and byproducts.
Chromium-6 was detected at 0.0608 ppb, which is 3x the EWG health guideline. There's no separate federal limit for chromium-6, only total chromium. A reverse osmosis system is the most effective removal method. All measurements are within federal legal limits. The EWG guidelines represent a more conservative, health-based standard.
How Hard Water Affects Your Home
At 285 PPM, untreated hard water has measurable effects on household costs and appliance life:
- Water heater inefficiency: Scale insulation forces the heater to work harder (DOE estimates up to 22% more energy for heavily scaled units)
- Soap and detergent: Hard water reduces lathering, requiring significantly more product
- Appliance replacement: Water heaters, dishwashers, and washing machines fail 2-4 years earlier due to scale buildup
- Plumbing maintenance: Scale buildup in pipes reduces flow and requires more frequent service
Note: Impact varies by household size, water usage, and local energy costs. A home water test provides the most accurate assessment for your specific situation.

About New Braunfels's Water Supply
Water Utility: New Braunfels Utilities
Water Source: Edwards Aquifer groundwater (Surface Water)
Population Served: 116,477
Hardness: 285 PPM (16.7 grains per gallon)
New Braunfels's drinking water comes from surface sources — Edwards Aquifer groundwater. Surface water requires more extensive treatment than groundwater, including coagulation, filtration, and disinfection. This heavier chlorination is why disinfection byproducts tend to be higher in surface-supplied systems. Despite the treatment process, mineral hardness from the watershed carries through. The system serves 116,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request New Braunfels Utilities's Consumer Confidence Report (CCR) or test your own tap.

Water Softener Sizing for New Braunfels
At 285 PPM (16.7 GPG), here is how to size a softener for your New Braunfels home. Multiply hardness in GPG (16.7) by daily water usage (roughly 50 gallons per person). A family of four uses about 200 gallons/day: 16.7 GPG × 200 gal = 3340 grains/day. Over a 7-day regeneration cycle, that is 23,380 grains - a 32,000-grain softener is the right fit for most New Braunfels households.
