HOW HARD IS LITTLE ELM’S WATER?

200 ppm. That is 11.7 grains per gallon.
The Little Elm water quality report lists a total hardness of 200 ppm as its highest result, with a reported range of 96 to 200 ppm (5.6 to 11.7 grains per gallon). On the USGS hardness scale that is moderately hard to very hard water.
COMMON SIGNS OF HARD WATER
What 11.7 grains per gallon looks like at home.
At about 11.7 grains per gallon, every one of these shows up in Little Elm sooner or later. The water test tells you how soon.
Cloudy glassware and white spots the dishwasher cannot rinse off: about 11.7 grains of dried mineral per gallon.
The white crust is limescale. It narrows spray holes and seizes aerators and valves.
Calcium and magnesium react with soap before it foams: more soap, and scum on tubs and shower doors.
The same soap curd settles on skin and hair and does not rinse away.
Minerals bind to fabric and detergent. Towels come out stiff, whites go grey, colors fade sooner.
Scale coats heating elements and clogs small valves, so appliances work harder and fail sooner.
LITTLE ELM’S WATER, BY HARDNESS
District lake water, not Lewisville Lake, moderately hard to very hard
Little Elm wraps around an arm of Lewisville Lake, and the lake is a drinking water reservoir: the Texas Water Development Board describes it as a Corps of Engineers lake on the Elm Fork of the Trinity in Denton County, holding 598,902 acre-feet over 27,175 acres at its conservation pool, impounded from November 1, 1954 and built to supply Dallas and Denton. None of that water reaches a Little Elm tap. The town's 2025 water quality report says its water is bought from the North Texas Municipal Water District, whose supply is reservoir water with Lavon Lake first among its sources, and it records the state's susceptibility rating for those sources as low. Lavon, the district's largest source, is a Collin County reservoir on the Trinity's East Fork, 20,622 acres and 412,598 acre-feet at conservation pool. So the water in a Little Elm kitchen was treated by the district and piped in, and the lake outside the window is Dallas's and Denton's.
The report's secondary table is the district's Wylie plant data, and it supplies the page's figure: a 2025 total hardness peak of 200 ppm on a range of 96.0 to 200, which spans the moderately hard and very hard classes, 5.6 grains per gallon at one end and 11.7 at the other. The minerals behind the number are listed with it: calcium from 31.2 up to 61.3 ppm, magnesium from 6.27 up to 9.44 ppm, total alkalinity 43.6 to 138 ppm, dissolved solids 182 to 455 ppm and sodium 41.9 to 88.0 ppm, alongside chloride at 29 to 92.5 ppm and sulfate at 84.7 to 147 ppm, and a pH running 7.3 to 8.8. The same figures appear in Allen's 2026 report under the heading of the Wylie plant, which is how we know which plant Little Elm's table describes. The district's own word for this water is moderately hard, the result of the minerals in Lavon Lake, and its advice is to divide the mg/L figure by 17.12 to get grains.
Hardness in Little Elm follows the district's lake blend across the year: the 96 end of the range is the softer season, the 200 end the harder, and every street gets the same water because the report lists no source other than the district. A lakeside address does not change the number. The federal SDWIS facility list for the town, system TX0610035, records its hardware and its past: the Mansell pump station at 2600 Red Spruce with 5 and 2 million gallon ground tanks and four service pumps, three rated 2,780 gallons per minute and one 1,580, elevated tanks of 1.0 million gallons at 3003 FM 423 and 2.0 million at 2450 Eldorado, and a roster of wells, North, Main, Preston, Chinese, Poland and Walker among them, all marked inactive, several plugged, together with the inactive Sunrise Bay and Garza Road well plants on the west side. The report adds a 2025 water loss estimate of 106,524,717 gallons and a service line inventory that found no lead, galvanized or unknown lines. The report's general note is that constituents which change taste, color or odor are not necessarily a health concern, and its hardness row attributes the mineral to naturally occurring calcium. Choose a softener for the 200 end of the range, about 12 grains per gallon, on a metered valve so it rests when the water lightens, and let the free water test give the figure at your tap on the day.

HOW A SOFTENER WORKS
Ion exchange, salt and regeneration.
One tank of resin, one tank of salt, and a valve that runs the cycle.
Resin beads hold sodium ions. Calcium and magnesium swap onto the beads as water passes, and the water leaves at close to zero grains.
When the beads fill up, brine from the salt tank rinses the hardness to the drain and reloads the sodium, metered by the gallons you use.
Calcium, magnesium and a little dissolved iron. Not chlorine, chloramine, PFAS, lead or taste: that is a filter’s job, so see whole house water filtration for Little Elm, and a reverse osmosis tap or bottled water delivery for drinking water.
A salt-free water conditioner turns hardness into crystals that stay in the water instead of on heaters and pipes: no salt, no drain, less scale, no relief for soap and skin.
HARDNESS QUESTIONS, ANSWERED
The hard water FAQ for Little Elm.
Is Little Elm’s water hard?
Yes. Little Elm's 2025 report prints total hardness of 200 ppm at its highest, on a range of 96.0 to 200, moderately hard to very hard, about 5.6 to 11.7 grains per gallon. That is North Texas Municipal Water District lake water from the Wylie plant, not water from Lewisville Lake, and the whole town gets the same supply.
Is hard water safe to drink?
Yes. Hardness is calcium and magnesium, minerals with no federal drinking-water limit. It is a plumbing, appliance, soap and skin problem, not a health one.
Does a softener make my water salty?
No. The salt goes down the drain at regeneration; the water carries a little sodium in proportion to the hardness removed, which a reverse osmosis tap removes again.
THE SOURCE MATTERS
Where the number comes from.
Each figure is read from the document linked beside it, in its own units and period. A missing result stays missing; a range stays a range.
