Whole House Water Softeners in Euless

The Trinity River Authority's Tarrant County treatment plant sits on Trinity Boulevard at the line between Fort Worth and Euless, with a Euless address, and the city's water page traces the water that reaches it: pumped from Cedar Creek Reservoir and Richland Chambers Reservoir in East Texas into Lake Arlington, then to the plant, then out to Euless, Bedford, Colleyville, Grapevine and North Richland Hills. The page calls that the primary source and names the secondary: city wells in the Trinity Aquifer. The 2025 water quality report says the same, surface water from the authority and groundwater from Euless wells, and the city's capital budget shows the wells are working assets, with pump and motor work on the Far North Well and repairs to the Fuller Well recorded in its project history. Fort Worth's 2017 planning documents list the authority's project only as an emergency connection, so Euless water is authority water and well water, not Fort Worth's.

Euless' report does something its neighbors' reports do not: it prints two columns of secondary constituents, one for the authority's water and one for the city wells, and the two are different waters. The wells column shows 150 ppm of total hardness as calcium carbonate on March 19, 2024, calcium 117 ppm, magnesium 0.753 ppm, sodium 329.3 ppm, total alkalinity 426.4 ppm, chloride 121 ppm, sulfate 177 ppm, total dissolved solids 880 ppm and conductivity 1550 micromhos. The authority column, sampled February 27, 2025, gives hardness 110 ppm, calcium 38.0 ppm, magnesium 3.68 ppm, sodium 27.5 ppm, alkalinity 81 ppm and total dissolved solids 194 ppm. The 150 ppm figure on this page is the wells' result, the highest level the report shows. On the USGS scale 150 is hard, close to 8.8 grains per gallon, and 110 is moderately hard, close to 6.4. The well water also carries about 12 times the sodium and 4.5 times the dissolved solids of the lake water, which is the usual mark of deep Trinity groundwater; the surprise in Euless is that its hardness tested higher than the lake's, not lower.

Which water reaches a Euless tap depends on whether the wells are running and where they tie into the mains, which the report does not map, so a home can see lake water most of the year and a stiffer well blend in the weeks the city leans on groundwater. The sensible reading of the two columns is a range from 110 to 150 ppm with the top end real, not theoretical, because it is the city's own measured result. A softener sized to 150 ppm, which is 8.8 grains or so, handles both columns, and a metered valve will regenerate less in the months the lake water dominates. The free water test tells you which column your tap is drinking on the day, and that is the figure we size to.
