HOW HARD IS ADDISON’S WATER?

No hardness figure on file for Addison yet.
Addison buys all of its water, already treated, from Dallas, whose plants work lake water from the Elm Fork and East Fork systems; Addison's own 2025 report prints no hardness figure.
COMMON SIGNS OF HARD WATER
What each grain per gallon looks like at home.
With no figure for Addison, the signs are the measure. Three or more of these, and the free water test will put a number on it.
Cloudy glassware and white spots the dishwasher cannot rinse off: the minerals that dry out of every 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.
ADDISON’S WATER, BY HARDNESS
Dallas plant water pumped through Addison's own stations, no printed figure
Addison owns the pipes and pumps but none of the water. The town's 2025 water quality report says it purchases all of its water from the City of Dallas, which treats it at one of three plants before it reaches the town. Where Dallas's own 2023 memorandum splits those plants by source, the Elm Fork and Bachman plants on lakes Ray Roberts, Lewisville and Grapevine through the Elm Fork of the Trinity and the East Side plant on Ray Hubbard, Tawakoni and Fork, Addison's report does not say which plant feeds the town. Once the water crosses the town line it moves through Addison's own system: the Celestial Pump Station on Celestial Road, the Surveyor Pump Station on Surveyor Boulevard, the Addison Water Tower on Addison Road and the Arapaho Water Tower on Arapaho Road, all listed in the town's facilities guide. Pumps and towers set the pressure in Addison's mains; they do not change what is dissolved in the water.
On hardness, the town's report is silent. Its 2025 table of secondary substances, drawn from Dallas's data, lists only aluminum at 5 parts per billion in a range of not detected to 8, and manganese at 2.27 in a range of not detected to 6.8; there is no hardness, calcium, magnesium or alkalinity row, so no Addison figure appears on this page. The supplier's own statement stands in its place: Dallas's memorandum gives 120 to 155 mg/L as calcium carbonate for Dallas water. In grains per gallon Dallas's range is 7 to 9, and in USGS terms it is hard water from 121 up, with only the floor of the range in the moderately hard band. It is Dallas's number for the Dallas system rather than an Addison measurement, and it is presented here as the supplier's, not the town's. What the Addison report does show is how the town's own pipes change the water on the way: Addison's chlorine residual averaged 2.76 ppm in a range of 1.24 to 3.93 against Dallas's 2.97 in a range of 2.75 to 3.18, and the town's haloacetic acids and trihalomethanes read 14 and 17 ppb. Disinfectant levels fall and byproducts form in a distribution system; calcium and magnesium are neither added nor removed by it.
So an Addison tap carries Dallas plant water with Dallas's mineral load, pressurized by the town's two pump stations and held in its two towers. An apartment tower and a house in the older part of town are on the same supply; what differs is the plumbing and how long the water sits in it. For a softener the working assumption is 9 grains per gallon, the top of what Dallas reports, and the free water test swaps that assumption for a measurement at your own faucet.

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 Addison, 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 Addison.
Is Addison’s water hard?
Addison's own 2025 report prints no hardness figure, so none is shown for the town. Every drop is Dallas-treated water, and Dallas's December 2023 memorandum describes its system as 120 to 155 mg/L as calcium carbonate, 7 to 9 grains per gallon, which the USGS scale calls hard above 120. A free water test at your Addison tap supplies the town's missing number.
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.
