The Trails of Frisco Water Hardness & Quality Report (2026)

The Trails of Frisco, Texas — a master-planned community in Frisco, Collin County, one of the premier residential developments in North Texas, part of the rapidly growing Frisco metropolitan area that has been among the fastest-growing cities in the United States for two consecutive decades — draws its municipal water supply from the North Texas Municipal Water District (NTMWD) reservoir system (Lake Lavon and Lake Chapman) via the City of Frisco Water Utilities. Water hardness measures 123 mg/L — classified as moderately hard.

The Trails of Frisco's moderate hardness — dramatically softer than many North Texas communities on the same calcareous Trinity watershed (DFW communities typically range from 250–450 mg/L) — reflects the NTMWD's exceptional water treatment capacity and Frisco's purpose-built distribution infrastructure. The NTMWD serves one of North Texas' most rapidly growing corridors and operates some of the most advanced water treatment plants in Texas, with effective lime-soda softening and coagulation-filtration processes that dramatically reduce the Cretaceous calcareous watershed's hardness. Frisco's distribution infrastructure is entirely modern (the city grew from 20,000 in 2000 to 200,000+ today), producing the moderate 123 mg/L in the newest north Texas suburban mains.

At 123 mg/L, The Trails of Frisco residents encounter moderate scale accumulation. Faucet aerators and showerheads develop deposits after several months — monthly cleaning with citric acid solution is practical maintenance. City of Frisco Water Utilities consistently delivers water meeting all Texas TCEQ and EPA Safe Drinking Water Act requirements.
