Belton Water Hardness & Quality Report (2026)

The City of Belton Water Company serves approximately 20,378 residents in Belton, Bell County, Texas. The utility purchases treated surface water primarily from Bell County Water Control and Improvement District #1 (BCWCID #1), which treats water from Belton Lake on the Leon River. Additional supply comes from Central Texas Water Supply Corporation (CTWSC), sourcing from Stillhouse Hollow Lake. The utility is located at 1502 Holland Road, Belton, TX 76513 and can be reached at 254-933-5823.

Belton Lake lies in the upper Brazos River basin, with inflows from the Leon River watershed spanning the Grand Prairie and Edwards Plateau transition. Cretaceous-age carbonate rocks — including the Glen Rose Limestone, Paluxy Sandstone, and Comanche Series limestones — dominate the catchment, leaching minerals into runoff. This geology imparts a hard character to the reservoir water, with seasonal dilution from high summer inflows temporarily reducing mineralization; the supply is entirely surface-derived with no groundwater aquifer involved.

Very hard water in Belton accelerates scale buildup in water heaters, dishwashers, washing machines, and plumbing fixtures, shortening appliance life by 30–50% and raising energy costs up to 50% from limescale insulation. Kettles, coffee makers, and showerheads clog fastest, reducing flow and efficiency. Monthly vinegar descaling helps, but a whole-house water softener is strongly recommended to eliminate issues and protect pipes. Belton Lake water averages 240 mg/L dissolved solids, 40 mg/L chloride, and 30 mg/L sulfate; potential contaminants include chlorodibromoacetic acid, aluminum, and fluoride per reports, with treatment involving disinfection and basic processing at supplier plants.
