Whole House Water Softeners in Midlothian

Midlothian's water is made at two city plants, the Tayman plant on Tayman Drive and the Auger plant on Auger Road, and they stand on two different raw supplies. The first is Joe Pool Lake. The Trinity River Authority is the lake's local sponsor and in 1976 acquired the right to its conservation storage, a water right to impound 176,900 acre-feet and divert 17,000 acre-feet a year, which it contracted out to four cities; Midlothian's share of the yield is 39.19 percent, second only to Cedar Hill's. When the other three cities joined a regional intake project in 1985, Midlothian chose to build its own raw-water pump station and treatment plant instead, and it is the only one of the four drawing on the lake today, from an intake on the lake's southeast leg that the Corps of Engineers says pulls anywhere from 1.0 million gallons a day in winter to 9.0 million in summer. The second supply is raw water from the Tarrant Regional Water District, which the city's 2025 report lists as Richland-Chambers water delivered through the district's pipeline. The Tayman plant had a peak capacity of 12 million gallons a day in 2024, with expansion to 24 planned, and the contractor that built the city's Water Treatment Plant No. 2 describes it as a 9 MGD plant with a reverse osmosis membrane system fed from a tap on the district's 72-inch and 90-inch raw-water lines.

The city's report prints no hardness figure, and the susceptibility report bound into it describes only the sources: Joe Pool Lake, operational, and one old city well screened between 2,080 and 2,344 feet, now expired. Both raw supplies are reservoirs, and a reservoir's mineral content is whatever its watershed washes in, in Joe Pool's case from the roughly 304 square miles that Walnut Creek and Mountain Creek drain. We found no published hardness for Joe Pool water. For the Tarrant Regional water there are neighbors' figures: Mansfield's 2025 report, on the same Cedar Creek and Richland-Chambers water, gives Mansfield's own water as 114 ppm and a normal band of 90 to 120 mg/L, and Fort Worth's wholesale data for the same year shows 108 to 150 ppm, which it also states as 6 to 9 grains. Those are their plants' figures, not Midlothian's. The reverse osmosis unit matters here: reverse osmosis removes dissolved minerals, calcium and magnesium among them, so water leaving that unit carries less hardness than the lake water entering it. How much of the city's supply passes through it, and how that water is blended back, the report does not say.

So a Midlothian tap can carry Joe Pool water, Tarrant Regional water, or a blend, and the mix moves with the season, since the Joe Pool draw itself swings ninefold between winter and summer. The city also sells treated water onward to Rockett Special Utility District, so the same question travels down the line to Rockett's customers. Whichever plant made it, the minerals announce themselves the same way, as a film on shower glass and a crust on the kettle element, and they are not a contaminant. We will not put a number on the city from its neighbors' tables. A free water test at your kitchen tap settles it in minutes, and the reading it gives, not a regional guess, is what we size a softener to.
