Whole House Water Softeners in Westlake

Westlake's 2025 water quality report gives its printed page 9 to a table of secondary constituents, the rows that describe how water feels and tastes rather than whether it is safe. Total dissolved solids, the weight of everything dissolved in a liter, ran 182 to 244 ppm over the year. Conductivity, how readily the water carries a current and so a second gauge of its mineral load, ran 312 to 431 micromhos per centimeter. Sodium sat between 19.5 and 27.9 ppm, a low figure that says the dissolved load is rock mineral rather than salt. These are measurements Fort Worth made on the water it treats and sells, reprinted by the town, because Westlake owns no lake, well or plant of its own. The report states that the town buys its water from the City of Fort Worth, and the state's January 2024 Tarrant County summary names the Tarrant Regional Water District's lake system as Westlake's only current source, puts the town on its list of small systems dependent on one supply, and projects an unmet need of 3,563 acre-feet a year by 2070, 40 percent of demand.

In that same table Fort Worth prints its total hardness for 2025 as 108 to 150 ppm, a range it also states as 6 to 9 grains, and that Fort Worth range is the figure for Westlake: moderately hard at its low end and hard at its high end on the USGS scale. The dissolved solids and conductivity rows each move by about a third from low to high across the year, the same proportion as the hardness, which fits water in which the thing being measured each time is largely the same calcium and bicarbonate. Westlake's own pages of the report add what the town measures in its mains: lead at a 90th percentile of 1.65 parts per billion and copper at 0.292 ppm in 2025, both under their action levels, and a service line survey in the fall of 2024, done after the EPA chose the town for its Get the Lead Out initiative, that found no lead service lines anywhere in Westlake. Corrosion control itself is Fort Worth's job, done by pH adjustment, as the town's report notes.

A single wholesale source has consequences at a Westlake tap. There is no well water to dilute the lake blend and no second supplier to switch to, so the hardness in every home, from the Solana offices to the newest subdivision, is whatever Fort Worth's blend carried that week, and the backup emergency generator the town is installing exists to keep that one feed moving through an outage. It also means the district's composite lake level, which the report says governs watering restrictions, is a fair proxy for the supply: Westlake stood at Stage 1, Water Watch, in 2025, with midday sprinkler use barred. Month to month the blend tilts between the West Fork lakes and the eastern reservoirs the district pumps toward Lake Benbrook and Eagle Mountain Lake, and the hardness follows. For a softener, take the upper figure, 150 ppm or 9 grains per gallon, as the design point, and let the free water test show where the blend sits at your tap on the day.
