Whole House Water Softeners in Lake Worth

The reservoir that gives the City of Lake Worth its name impounds the West Fork of the Trinity River and belongs to Fort Worth, which the Texas Water Development Board lists as both owner and operator. The lake held 33,495 acre-feet at its conservation pool of 594 feet when the board surveyed it in 2001, spread over 3,458 acres, and it was built for municipal supply and recreation with no design allowance for storing floodwater. Fort Worth's permit on the lake is 11.85 million gallons a day, and a city planning document notes Fort Worth lets that right be operated as part of the Tarrant Regional Water District's West Fork system, alongside Eagle Mountain Lake and Lake Bridgeport upstream. The intake and pipeline that carry Lake Worth water to Fort Worth's plants are rated at 127 million gallons a day, and the raw water goes to Fort Worth's treatment, not to the City of Lake Worth directly. The city's 2025 report classes its system as surface water bought from Fort Worth (Fort Worth's system, TX2200012), and lists two city well sites beside that line.

The hardness numbers in the city's report are Fort Worth's, reprinted on page 4 under a heading that says the information is provided by Fort Worth because the city buys its treated water there. The 2025 total hardness line reads 108 to 150 ppm as calcium carbonate, with a grains column of 6 to 9 per gallon. The table beneath it shows where that hardness comes from, calcium of 37.6 to 48.1 ppm against magnesium of only 3.45 to 7.35 ppm, and how little else is dissolved: sodium of 19.5 to 27.9 ppm and total dissolved solids of 182 to 244 ppm, at a pH of 7.8 to 8.5. Divide by 17.1 and the range is about 6.3 to 8.8 grains: moderately hard at the low end of the year and hard at the high end, by the USGS scale. The same page records that Fort Worth controls corrosion by adjusting pH, a practice that keeps the water on the alkaline side where calcium carbonate drops out as scale in a heater rather than staying dissolved. The city's own page 2 sampling, at Caddo Trail and William Springs, found chloramine averaging 2.10 ppm across the year.

Two things shape what a Lake Worth tap actually sees. The first is Fort Worth's blend: the 108 and the 150 are the ends of one system's year, moved by lake levels and by which plants carry the load. The second is the city's own wells, one site off Azle Avenue at the Highway 820 crossing and one at the boat club pump station, for which the report prints no separate hardness; a home near either site may take a share of groundwater that the Fort Worth range does not describe. Size a softener to 150 ppm, about 9 grains, and let the free water test confirm whether your tap runs at Fort Worth's number or somewhere the wells have moved it. The federal facility inventory shows how the two supplies meet. It lists the Fort Worth connection with a sampling station at 6108 Lakeside Drive, and two small well plants of the city's own: Plant 3 at 6001 Azle Avenue, with a 0.130-million-gallon ground tank and a 400-gallon-a-minute pump, and Plant 5 at 4200 Boat Club Road, with a 0.205-million-gallon ground tank, two 600-gallon-a-minute pumps and the city's single elevated tank of 1.000 million gallons. Both wells are coded as permanent sources rather than emergency ones, in a system of 2,633 service connections for 4,720 people.
