Whole House Water Softeners in St. Paul

St. Paul's water comes through a utility small enough to know its customers by count. Wylie Northeast Special Utility District says it supplies 1,484 residential and 115 commercial customers, who use an average of about 11,000 gallons per household each month, and its 2025 water quality report names the source as Lake Lavon in Collin County, purchased as treated water from the North Texas Municipal Water District's Wylie plant. The district's office, tank and tower stand on land it leased from the Town of St. Paul on October 1, 1975, and the district says that tank and tower can supply the whole system on their own, with the older St. Paul tower adding a boost; the state named it a Superior Water System in December 2015. Its board meets on the second Monday of each month at 2 p.m. at the office on Parker Road in Wylie, which is where a St. Paul resident with a question about the water goes. At its first annual meeting, on January 16, 1967, the corporation reported eight months of operation and 5,385,000 gallons used. In the federal SDWIS inventory, system TX0430051, Wylie Northeast shows two live connections to the district's lines and two pumping sites: 745 Parker Road, with a 0.500 million gallon elevated tank, a 0.300 million gallon ground tank and two 1000 gallon a minute pumps, and 2780 Aztec Trail, with a 0.350 million gallon ground tank and two 1500 gallon a minute pumps.

The 200 ppm as calcium carbonate on this page is the peak total hardness reading in the district's 2025 report, which gives 96.0 to 200 ppm as the range, between roughly 5.6 and 11.7 grains per gallon, moderately hard at the bottom of the year and very hard at the top. The report's secondary constituents table, which is the Wylie plant's data, also carries the plant's sodium, peaking at 88.0 ppm, its alkalinity, between 43.6 and 138 ppm, and its dissolved solids, between 182 and 455, and it introduces the table by noting that constituents like calcium, sodium and iron can affect taste, color and odor without being a health concern. The supplier's own water quality page rates the treated water moderately hard and traces that to Lavon Lake, iron and lime among the minerals it lists. The 2025 report's own distribution rows put the chloramine residual at an average of 2.34 ppm across a 0.50 to 3.80 range, lead at 2 ppb and copper at 0.782 ppm at the 90th percentile.

A district of this size does not blend sources or run separate pressure planes with different water in each. Its report and its history page describe one supply, one plant and one set of tanks, so what reaches a St. Paul tap is the Wylie plant's water after a stop in the district's tanks; a reading of 6 grains and a reading of 11 in the same town are the lake in different months. The lake shore setting makes no difference either, since the water is piped from the plant rather than drawn at the town. What a household sees is what the district's supplier describes: cloudy spots on dried glassware, a lime line at the faucet and a heater that gathers deposits over the years. For a softener, size to the 200 ppm end, 12 grains or so, and let the free water test place your own tap within the 96 to 200 range on the day it is measured.
