Whole House Water Softeners in Keller

Keller's water system receives and lifts; it does not treat. The city's utility map marks City of Fort Worth 24-inch and 16-inch transmission lines where the supply enters, and then Keller's own equipment takes over: pump stations at Alta Vista, Katy Road, Keller High School and Pearson 1 and 2, ground storage at Pearson 1, Pearson 2 and Keller High School, and elevated tanks named Whitley, Keller Smithfield and Knox. Those feed three pressure planes the map labels North, High and Low. The city's 2025 budget sums the network at 296 miles of mains and 10 million gallons of storage and names Fort Worth as the wholesale provider whose contract the water fund pays each year, with Keller's own crews responsible for sampling, testing, delivery and tank, pump station and pipeline upkeep. In 2025 Keller bought 3,236,072,300 gallons from Fort Worth, the figure its water quality report gives in its water loss audit. A 2017 Fort Worth planning study lists the portion of Keller it serves at 100 percent. The federal facility inventory fills in the plumbing: three wholesale connections, two straight from Fort Worth and one routed through Southlake, feeding ground storage of 5.500 million gallons at Alta Vista and 3.000 million at each Pearson station, with elevated tanks of 1.000 million gallons at Keller Smithfield and 1.500 million each on Knox Road and Shady Lane; the Alta Vista pumps are four 3,000 gallon-a-minute units. Southlake's capital program adds the age of the shared supply: the Alta Vista pump station near Ray White Road was built in 1984, and Keller holds a 50 percent share in the 36-inch and 30-inch Alta Vista supply line. Keller's 2025 budget sets wholesale water at $9,880,565.

The hardness in that water is set upstream at Fort Worth's plants, and Keller's report prints Fort Worth's sampling results for secondary constituents under exactly that heading. Total hardness as calcium carbonate 108 to 150 ppm; total hardness in grains 6 to 9 per gallon; and then, all in ppm, calcium 37.6 to 48.1, magnesium 3.45 to 7.35, sodium from 19.5 to 27.9, alkalinity 99.7 to 124, dissolved solids 182 to 244, chloride 16.3 to 31.8, and a pH of 7.8 to 8.5. Keller's glossary defines grains per gallon as a unit of water hardness, which is the unit softeners are sized in, and the span works out to about 6.3 to 8.8 grains. Keller's water sits in the USGS moderately hard class at 108 ppm and in the hard class at 150, so it moves between the two over a year.

Three pressure planes do not mean three kinds of water. All of it is Fort Worth water, and the plane only decides which tank and which pump station it passed through on the way to your street. What moves the number at a Keller tap is the season and Fort Worth's mix of West Fork reservoirs and East Texas reservoirs, which is why the supplier prints a range rather than a single result, and why a home in the North plane and a home in the Low plane should expect the same range rather than different numbers. For a softener, plan on the top of that range, about 8.8 grains per gallon; a metered valve can then stretch the time between regenerations when the blend runs toward 108. The free water test measures your own tap, and that measurement is what we size to.
