Whole House Water Softeners in Melissa

Melissa's 2025 water quality report prints two complete sets of district data, one headed NTMWD Wylie Water Treatment Plants and one headed NTMWD Leonard Water Treatment Plants, because the city can receive water from either. The Leonard side begins at Bois d'Arc Lake, which the Texas Water Development Board records on Bois d'Arc Creek in Fannin County at 16,526 acres and 367,609 acre-feet at its conservation pool, with impoundment from April 14, 2021 and diversions to the treatment plant from March 2023. The report also explains the taste of late summer: each July and August, lakes can experience natural algae blooms, and blue-green algae release compounds with a grassy or earthy character that the district's laboratory watches for and treats with extra steps, without changing the quality of the finished water. On minerals the report is plain. Calcium, sodium and iron are what the state, not the EPA, regulates as secondary constituents, and they affect appearance and taste rather than health. The report lists the city's well as a source but prints no separate results for its water. Melissa's own part of the system is the network. The report counts 161 miles of distribution lines, 8,998 active residential connections and 1,625 fire hydrants, names the North Elevated Storage Tower and a leak detection and repair program among recent investments, and puts the 2025 water loss at 53.19 gallons per connection per day. The federal SDWIS facility list for system TX0430040 adds a 2.0 million gallon elevated tank on Throckmorton Road, a Central Street pump station with 0.75 million gallons elevated, 0.5 million on the ground and three 1,350 gallon-per-minute pumps, a Surrey Circle station with a 0.25 million gallon ground tank, two 700 gallon-per-minute pumps and the well, and records 26,234 people served.

The figure on this page, 200 mg/L, is the highest 2025 result from the Wylie plants, whose range ran 96.0 to 200: moderately hard where the year bottoms out and very hard where it peaks, roughly 5.6 grains per gallon rising to 11.7. The Leonard column is gentler, 96.0 to 144 mg/L, hard rather than very hard at its peak, about 8.4 grains. The two columns differ in exactly the minerals a softener removes. The Wylie rows show calcium of 31.2 to 61.3 ppm with magnesium of 6.27 to 9.44 ppm; the Leonard rows show calcium of 39.7 to 52.4 ppm and a flat 2.69 ppm of magnesium. Dissolved solids tell the same story, 182 to 455 ppm from Wylie against 194 to 253 from Leonard, and sodium was 41.9 to 88.0 ppm from Wylie against 21.7 to 34.6 from Leonard. Both are reservoir waters, and both plants deliver what the district calls moderately hard water, a description it ties to the minerals in Lavon Lake for its Wylie supply, to be converted to grains by dividing mg/L by 17.12.

Which column applies at a Melissa tap depends on which delivery is feeding that part of the system on that day, and the report does not map the two connections to streets. The safe reading for a homeowner is the Wylie range, because it contains the Leonard range entirely and sets the ceiling at 200. In practice a Melissa kitchen can see anything from about 5.6 to 11.7 grains across a year, and the gap between a spring month and an August month can be wider than the gap between the two plants. Size a softener to the top of the Wylie range, about 12 grains per gallon, let a metered valve regenerate less often when the water runs lighter, and use the free water test to learn which water, and how much hardness, your own tap carried on the day.
