Whole House Water Softeners in Murphy

Murphy owns no lake and no well. The city's 2024 water conservation plan lists one source, purchased treated water from the North Texas Municipal Water District, and describes the system that carries it: about 6,406 meters across 5.70 square miles, two elevated tanks and three ground storage tanks holding 5.25 million gallons between them, and 94 miles of distribution lines. The city's 2025 water quality report adds the district's side: Lavon Lake is the district's main raw water source and the reservoir where supplies pumped in from Lake Texoma, Jim Chapman Lake, Lake Bonham and the East Fork wetland are held, with contracts through the Sabine River Authority for Lake Tawakoni water and the Greater Texoma Utility Authority for more Texoma water. The city's own page puts system pressure at 60 to 70 pounds per square inch and notes that a diesel generator now backs the renovated pumping so service holds through a long outage. The federal SDWIS inventory for Murphy, system TX0430042, names the hand-off point: a single purchased-water connection from the district, Murphy 2, feeding the North Star pump station at 600 Hawthorne Drive, where ground tanks of 2.0, 1.0 and 0.25 million gallons sit beside pumps rated from 800 to 4,000 gallons a minute, and two 1.0 million gallon elevated tanks, one at 1300 Rodeo Drive and one on Betsy Lane. The city's meter division reads its meters in three cycles over a fixed automatic reading system that relays the data daily across the city's Wi-Fi, and it maintains about 800 fire hydrants.

Murphy's number, 200 mg/L as calcium carbonate, is the highest level detected for total hardness in the city's 2025 report, inside a published range of 96.0 to 200 mg/L, or roughly 5.6 to 11.7 grains a gallon. The row that deserves a second look in Murphy's table is sodium: 88.0 ppm at its highest, in a range of 41.9 to 88.0, which the report attributes to erosion of natural deposits and oil field by-products. Sodium does not count toward hardness, which is the calcium, running between 31.2 and 61.3 ppm, and the magnesium, between 6.27 and 9.44; it belongs instead to the 182 to 455 ppm of total dissolved solids, alongside chloride at 29.0 to 92.5 ppm and sulfate at 84.7 to 147 ppm. It matters here because a conventional softener works by trading calcium and magnesium for sodium, so softened Murphy water carries more sodium than the 88 ppm it arrived with. The district's one-line verdict on this water is moderately hard, and it points at Lavon Lake for the reason. Murphy's own chlorine residual in the 2025 report averaged 2.8 ppm across a 0.7 to 3.5 range.

At a Murphy tap all of this arrives together, and at the same strength on every street, because the city has one supplier and one treatment source. The report's water loss audit, an estimated 181,190,682 gallons lost in the year, is about leaks and meters, not about quality; the hardness that leaves scale on a shower door and in a water heater is the same whether the house is near the Hawthorne area pumps or at the far end of the 94 miles. The 60 to 70 psi the city maintains pushes that water through a softener without trouble, and the seasonal swing from 96 to 200 mg/L is why we size to the top: a unit rated for about 12 grains covers the hardest month, and the free water test says which month your tap is in.
