Whole House Water Softeners in Lowry Crossing

Milligan Water Supply Corporation's 2025 water quality report devotes four of its pages to a single document, the North Texas Municipal Water District's Wylie Water Treatment Plants data for 2025, reprinted in full, because the Wylie plants are the one source Milligan has. The report's own source listing is a single line, surface water from the district, with its state source water assessment completed. The raw water is Lavon Lake, which the state water board records as a 20,622-acre Collin County lake on the Trinity's East Fork holding 412,598 acre-feet at conservation pool, its pools raised in a modification finished in December 1975. Milligan's own part of the story is the pipe: its distribution results show chloramines averaging 2.7 ppm across 2025, from 1.7 to 3.7, nitrate at 0.243 ppm, lead at a 90th percentile of 0.861 ppb and copper at 0.599 ppm at residents' taps. The federal SDWIS facility list for Milligan, system TX0430041, shows how compact the operation is: one pump station on Bridgefarmer Road with three service pumps rated 420 gallons per minute, ground storage there of 0.42, 0.060 and 0.040 million gallons, a 0.300 million gallon elevated tank at 3586 County Road 406, and one consecutive connection to the district's system TX0430044, with Lake Lavon named on the NTMWD meter record and 3,364 people served. The corporation's report adds that it has completed and filed its lead service line inventory, available by phone or on its website. Everything about minerals comes from the district's pages.

That district table is where the page's figure comes from: total hardness as CaCO3 of 200 ppm at its highest in 2025, with a range of 96.0 to 200, a span that starts in the moderately hard class and ends in the very hard class, or 5.6 grains per gallon at the bottom and 11.7 at the top. The table lists every mineral behind that figure. Calcium ran 31.2 to 61.3 ppm; magnesium 6.27 to 9.44; alkalinity as CaCO3 43.6 to 138; dissolved solids 182 to 455; sodium 41.9 to 88.0; sulfate 84.7 to 147; chloride 29.0 to 92.5, all in ppm, with pH between 7.3 and 8.8. Iron and aluminum were below detection, manganese sat at 0.002 ppm and zinc at 0.016. The table's own note on hardness is that it comes from naturally occurring calcium. The district's label for this water is moderately hard, a legacy of Lavon Lake's minerals, and it puts the conversion at 17.12 mg/L per grain.

For a Lowry Crossing household the arithmetic is unusually clean. There is no well in Milligan's system and no second plant, so the water at the tap is Wylie water, and hardness moves only with the district's lake blend and the season: nearer 96 ppm in the softer stretch of the year, nearer 200 in the harder. A house at one end of Milligan's lines and a house at the other see the same water in the same week. The report's calcium range, nearly doubling from low to high, is the swing a water heater feels between those seasons. Size a softener for the range's 200 end, about 12 grains per gallon, and choose a metered valve so it regenerates less when the lake runs light; the free water test tells you where the lake sits on the day it is drawn, at your own tap.
