Whole House Water Softeners in Flower Mound

Flower Mound's 2025 water quality report is laid out in three columns, Dallas, UTRWD and Flower Mound, because the town's mains carry two suppliers' water and the town samples the result. Dallas Water Utilities draws from the Elm Fork of the Trinity River and lakes Lewisville, Ray Roberts, Grapevine, Ray Hubbard, Tawakoni and Fork; Upper Trinity's Taylor plant in Lewisville takes Lewisville and Ray Roberts water, while the district brings Jim Chapman Lake water in through a pipeline it owns jointly with Irving. The federal facility record lists the town's receiving points by address rather than by supplier: a pump station at 1201 FM 407 with a 10 million gallon ground tank and five 7,000 gallon-a-minute pumps, a station at 708 Pintail Place with 3 and 2 million gallon tanks, a station at 6200 Stonecrest with a 5 million gallon tank, and elevated tanks of 2.5 million gallons on Freeman Road and 2 million on Bruton Orand.

Neither supplier's column prints hardness. The report says the secondary constituents that govern taste and scale, calcium, sodium and iron among them, are regulated by the state, are left out of the annual report and are available as monthly results on request. The columns do show that the two waters are not identical: fluoride averaged 0.627 ppm in the Dallas water, which Dallas fluoridates, and 0.26 ppm in the Upper Trinity water, which adds none; chloramine residual ran 2.97 and 2.93 ppm. For hardness the only published number belongs to Dallas, which told a council committee in December 2023 that its system runs between 120 and 155 mg/L, which the USGS scale calls moderately hard to hard and which works out near 7 to 9 grains. Upper Trinity's 2025 report lists no hardness result at all. Both are reservoir waters from the same basin, carrying the calcium and magnesium a lake gathers from its watershed, but no figure is shown for Flower Mound because the town's own report gives none, and this page does not substitute Dallas's.

Which supplier's water reaches which street is not something the report states, and with three receiving stations spread across a town this size the answer can differ between the FM 407 side and the Stonecrest side and may change through the year. In practice both waters leave the same kind of mark: spotting on glassware, scale in the kettle, a shorter life for the water heater. A softener sized for the Dallas range's upper end, 155 mg/L or about 9 grains, covers either supply without guessing which one you have. The free water test gives a Flower Mound address its own reading in ppm and grains per gallon, which is the number no report in this chain publishes.
