Whole House Water Softeners in Dalworthington Gardens

Dalworthington Gardens is a buyer with two sellers, and its 2025 report is really three reports bound together: a few pages of the city's own results, then Fort Worth's 2025 water-quality data for wholesale customers, then Arlington's. The city owns no treatment plant. The state's facility list shows what it does own: the pump station on Arkansas Lane where Fort Worth's main arrives, with 1,500-gallon-a-minute pumps and a 0.3 million gallon elevated tank and a 0.5 million gallon ground tank, a second station on Roosevelt Drive with two tanks, now inactive, and two old wells on Roosevelt and a plugged one on California Drive, left over from the years before the city went entirely to purchased water. Fort Worth's water, the report explains, is Lake Worth, Lake Bridgeport, Eagle Mountain Lake, Benbrook Lake, Richland-Chambers and Cedar Creek water plus the Clear Fork of the Trinity, and Arlington's is Lake Arlington and Lake Benbrook water along with Cedar Creek and Richland-Chambers, so both sellers are treating Tarrant Regional reservoir water, Fort Worth with three western lakes of its own added. The Tarrant Regional district itself does no treatment for drinking; it delivers the lakes' own chemistry to each city's plant.

The city's own pages print no hardness figure, so there is none for Dalworthington Gardens, but the two sellers' pages do. Fort Worth's 2025 secondary constituents table gives total hardness as calcium carbonate of 108 to 150 ppm, which it also prints as 6 to 9 grains per gallon, with calcium 37.6 to 48.1 ppm, magnesium 3.45 to 7.35, sodium 19.5 to 27.9, bicarbonate 99.7 to 120, total alkalinity 99.7 to 124, sulfate 17.3 to 40.9, chloride 16.3 to 31.8 and total dissolved solids 182 to 244, at a pH of 7.8 to 8.5. On the USGS scale that range runs from moderately hard to hard, crossing the 120 line. Arlington's 2025 figure is 94 ppm on average, ranging 80.4 to 110, moderately hard from end to end. Those are Fort Worth's and Arlington's figures for the water leaving their plants. Fort Worth also notes that it adjusts the pH of its water to keep it from corroding pipes, which is a matter of chemistry balance rather than hardness. The profile both tables show is classic North Texas lake water: moderate calcium with a little magnesium, carried mostly as bicarbonate, and low sodium.

Whatever comes out of a Gardens tap began as one of those two waters or a mix of them, and which one depends on which connection is carrying the load. The report says the city buys from Fort Worth currently and also from Arlington, and it does not say how the flows are split or whether parts of the city sit closer to one main than the other, so a house on Arkansas Lane and a house near Pleasant Ridge may not be on the same water on the same day. At these levels a household sees spotting on dishes and some scale at the tap, mineral deposits rather than anything harmful. We will not print a number for the city from its suppliers' tables. The free water test tells you whether your tap that day reads like Fort Worth's water or Arlington's, and we size the softener to that result.
