Whole House Water Softeners in Corral City

Corral City is a very small incorporated town, with 27 residents counted in 2010 and 33 in 2020, sitting where Farm Road 407 meets Interstate 35W in southwestern Denton County. The whole town is about 100 acres at the southwest corner of FM 407 and I-35W, and in 2022 the mayor told the Cross Timbers Gazette that only 12 of them were in use; that year Hillwood, developer of Harvest across the farm road, bought all of it, gas station, convenience store, liquor store and RV park included. The town kept its own government, a mayor and four aldermen, and it has worn two names, becoming Draper in 2016 for former mayor and owner James Draper and reverting to Corral City less than four years later. A town that size runs no water utility of its own. The state public water system number that covers Corral City addresses is TX0610019, which belongs to Argyle Water Supply Corporation, so there is no Corral City water quality report; the corporation's annual report speaks for every meter on its lines, Corral City's included. The corporation's office is at 825 West FM 407 in Argyle, and its source table lists a well it calls Hwy 407 at 825 FM 407 W, so the office and one of the wells share an address on the same farm road that runs through Corral City. The corporation's board meets there on the third Thursday of each month at noon, which is where a Corral City resident takes a question about the water. Nothing the corporation publishes says which of its wells or storage tanks feed Corral City in particular.

The figure that applies to the town is the corporation's: 76.8 mg/L of hardness as the 2025 average for the system. On the USGS scale that falls in the moderately hard band, and it converts to roughly 4.5 grains a gallon. The water behind that number arrives in Corral City by two routes. Part is groundwater from the corporation's wells in the Trinity Aquifer in Denton County. The rest is treated lake water from the Upper Trinity Regional Water District, whose connection the corporation’s source table lists at 900 North Kealy Avenue in Lewisville. The district pumps raw water from Ray Roberts Lake and Lewisville Lake, plus Jim Chapman Lake water routed through Lewisville Lake, treats it at the Thomas E. Taylor plant, and moves the finished water through its transmission system to its member and customer utilities, more than 20 of them. The district explains its reliance on lakes plainly: the region has limited water underground to pump. How much of a Corral City gallon is lake water and how much is well water is not something either the corporation or the district publishes. The Gazette's 2016 account also recalled Mayor Draper working with Argyle's mayor on regional water and sewer utilities for the corner.

For a resident, living under someone else's report has a practical meaning. When the corporation writes that its water meets every standard, that is Corral City's water; when it prints one hardness average, that single number is spread across the whole system, and the report does not say whether the sample it rests on was pumped from a well, bought from the district, or drawn from the mains where the two have already mixed. A reading on a Corral City street could sit a little above or below 76.8 depending on which source is doing more of the work that week and what the summer demand for lawns pulls in from the district. The free water test is the way to replace the system average with the number at your own kitchen sink, and a Corral City softener should be matched to that reading, taken at the higher end of what the year delivers.
