Water quality
Alamogordo's water is
very hard. Here's the number.
Every figure on this page comes from the City of Alamogordo's own water quality report or from the US Geological Survey, and the source is printed underneath it. Nothing here comes from a water-softener brochure.
Where Alamogordo sits
Grains per gallon. Class boundaries from the US Geological Survey water hardness scale; Alamogordo's figure from the City of Alamogordo Consumer Confidence Report, 2025 — 652 mg/L, which the report itself converts at 17.1 mg/L per grain. The City's own utilities FAQ describes the supply as "very hard," at 34–39 grains per gallon.
What it actually does
Calcium and magnesium come out of solution when water is heated or left standing. In a water heater that means a layer of scale in the bottom of the tank, between the burner and the water it is supposed to be heating. The burner runs longer, the steel runs hotter, and the tank gets to the end of its life sooner.
Elsewhere it shows up as a shower valve cartridge that gets stiff, an aerator that halves the flow, a toilet fill valve that starts to weep, a dishwasher that leaves a film, and a kettle you can hear.
The Department of Energy's national lab has looked at this properly — its report on water quality and residential water heating found scale measurably shortens equipment life and cuts efficiency. It also found the loss is nothing like the 40-odd percent the softener industry advertises. We'd rather quote the smaller, real number.

Why it matters more here
1980
median year an Alamogordo house was built
Roughly half the housing stock predates 1980, and 14% predates 1960 — the galvanised and cast-iron era. That's 45 years of this water.
US Census, American Community Survey 2024 5-year estimates
10.7 yrs
average age of a water heater when it fails
In a study of 700 water-heater insurance claims, 69% of failures were the tank itself leaking or bursting.

9,300 gal
wasted per year by the average household's leaks
A faucet dripping once a second is 3,000 gallons a year on its own — and City water rates went up sharply in 2024.

What actually helps — and what we do
- Flushing the water heater on a schedule that suits 38-grain water, not the one in the manual
- A correctly sized whole-house softener, plumbed into a proper loop
- A reverse-osmosis unit at the kitchen sink if the taste bothers you
- Flushing a tankless unit rather than waiting for it to throw a fault
- Replacing aerators and shower cartridges instead of the whole fixture
- Checking the anode rod before the tank goes, not after
Common questions
Is Alamogordo's water safe to drink?+
Yes. The City's Consumer Confidence Report shows lead and copper below action levels and every regulated contaminant inside its limit. Hardness is not a health measure — the City says plainly that there are no harmful health effects, only more scale and more soap.
Do I need a whole-house filter?+
The City actively discourages it, and we agree. Their position is that no filtering is necessary and that a badly maintained filter can make your water worse, not better. A softener is a different device with a different job: it takes hardness out so scale stops forming. That's what protects your plumbing.
How often should a water heater be flushed here?+
More often than the manual says, because the manual wasn't written for 38-grain water. Call and we'll tell you what makes sense for your unit and how it's been running.
Will a softener fix the spots on my glasses?+
Largely, yes — spotting is scale drying on the surface. Taste is a separate question, and that's what a reverse-osmosis unit at the kitchen sink is for.
