HOW HARD IS LUCAS’ WATER?

200 ppm. That is 11.7 grains per gallon.
The City of Lucas 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 Lucas 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.
LUCAS’ WATER, BY HARDNESS
Purchased Lavon Lake water, 96 to 200 ppm, very hard at the top
Lucas describes its supply in three words on the first page of its 2025 water quality report: purchased surface water, bought from the North Texas Municipal Water District and taken from Lavon Lake in Collin County. The city's job is to hold it and push it. Lucas operates two elevated tanks, and the newer one is a 750,000-gallon water tower on West Lucas Road that the City Council funded at $5,027,616 on October 19, 2023, with Landmark Construction building to a JTG Engineering design; the foundation was poured in December 2023, the tank was lifted onto its pedestal in June 2024, and a control valve on Winningkoff Road followed in February 2025. The city built it because, as demand grows, the system was at risk of failing to refill its elevated storage in the off-peak hours, a sizing question its Water Master Plan, updated in March 2023, works from the ultimate supply the district will deliver. In 2018 the city asked state regulators to add about 4,593 acres it was already serving to its water certificate, a measure of how far the lines reach. The federal SDWIS inventory for Lucas, system TX0430054, lists two active purchased-water connections from the district, labeled McGarity and Country Club, and the hardware behind each: at 2295 McGarity Lane a 0.350 and a 0.200 million gallon ground tank and pumps of 1,200 and 750 gallons a minute; at 915 Country Club Road ground tanks of 0.750 and 0.500 million gallons with 900 gallon a minute pumps; and a 0.300 million gallon elevated tank at 815 East Winningkoff Road.
The figure on this page, 200 ppm as calcium carbonate, tops the hardness line of the Lucas report, which gives 96.0 to 200 ppm as the reported range. In grains per gallon that runs from about 5.6 up to 11.7, moderately hard at the low end and very hard at the top of the USGS scale. The Lucas table carries the rest of the district's Wylie plant results for 2025, sodium up to 88.0 ppm, alkalinity to 138 and dissolved solids to 455, with calcium at 61.3 and magnesium at 9.44 at their peaks, and the report labels hardness itself as naturally occurring calcium. The district's water quality page says the same thing in plainer terms: its treated water is considered moderately hard, the lake's mineral load being the cause, lime among it, and homeowners can turn any mg/L figure into grains by dividing by 17.12. Lucas's own distribution rows in the 2025 report show a chloramine residual averaging 2.95 ppm within a 1.20 to 4.00 range, lead at 1.04 ppb and copper at 0.863 ppm at the 90th percentile.
In a city where the tower, not the terrain, sets the pressure, hardness is the one thing that does not vary by street. Every connection on those 4,593 acres and beyond receives the same district water, so a house that tests at 6 grains and a house that tests at 11 are reporting different months, not different mains. The district describes what the minerals do at home without drama: mineral spots as water evaporates, scale around faucets, and a heater that collects deposits over time and may need a plumber. For a softener the right number is the top of the range, 200 ppm, 12 grains near enough, so that the worst month is handled and a metered valve can simply regenerate less when the lake runs softer; our free water test puts a figure on your own tap the day we take it.

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 Lucas, 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 Lucas.
Is Lucas’ water hard?
Yes. Lucas' 2025 water quality report prints total hardness up to 200 ppm as calcium carbonate, in a reported range of 96.0 to 200 ppm, which is about 5.6 to 11.7 grains per gallon: moderately hard at the low end and very hard at the top. It is the district's Lavon Lake water, the same on every Lucas street.
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.
