Softeners for private wells in the Town of Mukwonago and Vernon
Around the village, the Town of Mukwonago and Vernon together hold about 15,200 people, and many of their homes are served by private wells. The DNR samples that put village water at 22 to 23 grains never touched those wells.
Call (262) 829-5961Mon to Fri, 7am to 5pmVillage samples don't cover your well
The June 2026 DNR figures, 390 and 370 milligrams per liter, came from the village's two entry points. A well serving a house in the town or in Vernon sits outside that system, and no report publishes a number for it.
Village water mixes deep and shallow sources on purpose. A private well sits outside that mix, and its hardness is known only once someone tests it.
Iron: the village built a plant for it
Mukwonago put an iron filtration plant on Well 5 in 2019 because of high iron there. Wells in this area can carry iron too, and a private well has no utility plant ahead of the faucet.
An iron line on your lab report is worth reading out on the call, right after the hardness figure. We look at every line of it before quoting.
Bacteria and nitrate are separate questions
A softener deals in calcium and magnesium; bacteria and nitrate were never part of its design. For bacteria, the Wisconsin DNR recommends that private well owners test no less than once a year, and putting in a softener leaves that advice standing.
How a well home gets quoted
Open the call by saying the word well, then give the head count, where the supply pipe comes in and if a softener is there now. Lab results help, and the reading at your faucet on install day confirms the starting number.
From there the job matches a village house: softener and brine tank at the supply pipe, bypass, drain hose to its air gap, the drinking-water faucet by the kitchen sink, and a faucet test that has to read zero.
Common questions
Will my well read about 22 grains like the village?
It might or it might not. There is no public number for any private well, which leaves two sources: a lab report or the test at your faucet.
How often does a private well need a bacteria test?
Once a year at the least, going by the Wisconsin DNR's advice. Having a softener leaves that schedule as it is, since bacteria and nitrate are not what it is designed to treat.
What if I don't have any lab results?
Call anyway. You get the price on the call regardless, and hardness at your faucet is checked before the plumber touches a pipe.
