Two supplies, one village
The Village of Menomonee Falls water utility runs two systems at once. Part of the village gets Lake Michigan water bought from Milwaukee Water Works. The rest is served from the Village's own wells.
The Village publishes both hardness figures in its utility FAQ: 7 to 9 grains per gallon for the Milwaukee water, 27 to 32 for village well water, or about 462 to 547 milligrams per liter. Having both in grains, from the Village itself, makes the job easier.
A fourfold gap, decided by your address
Put side by side, the well water runs roughly four times as hard as the lake water. That gap is too wide for one setting to fit both.
To find out which supply serves you, ask the Village utility with your street address. The plumber also confirms it with a test at your tap on installation day.
Why the setting has to match the water
A softener set for 8 grains in a house that gets 27 to 32 grain well water will not bring the tap to zero. One set for 30 in a house on lake water is set for water that house never sees.
That is why a quote here starts with your address, and the installation ends only when a test at your tap shows zero hardness.
Lake side or well side: an honest read
On the USGS scale, moderately hard runs up to 120 milligrams per liter and hard runs from 121 to 180, so 7 to 9 grains of lake water sits at the upper edge of moderately hard and reaches into hard. Softening there is a closer call, and we will say so.
On the well side, 462 to 547 milligrams per liter counts as very hard by any reading of the scale, far past the 180 line. There, softening is the main job.
Either way it is one system, a whole-house softener with the reverse-osmosis faucet included. Whether that is worth it on lake water is your call, and the phone call will be straight with you about it.
What happens on the call and after
Quotes run Monday to Friday, starting at 7am and ending at 5pm. Your street address does most of the work; add the number of people at home, where the main line enters and whether an old softener is already in place, and the price is given on that same call.
Nobody comes out to sell. A plumbing contractor licensed under Wisconsin law does the installation, because the drain connection and its air gap are plumbing by state statute, chapter 145.
Lannon, Butler and the village itself
This site is built around the Village of Menomonee Falls, where the state's 2026 estimate puts the population at 41,374. Its neighbors Lannon and Butler are covered as well.
The two hardness ranges on these pages belong to the Village of Menomonee Falls utility and describe the water it delivers. A house in Lannon or Butler starts instead from whatever its own supplier publishes, or from the lab report on its well.
Install day in a Falls house
The tanks go wherever your main line enters, which in one house is the basement and in another the garage or a utility room. Wherever it is, the spot needs somewhere to drain and somewhere to plug in. A corner that already holds an old softener tends to have both.
Before touching a pipe, the plumber reads the hardness at your tap, and that one reading shows which of the two supplies you are on. The day ends where it started, at the tap, with readings taken again and again until the test finds no hardness left.
The same package on either supply
Lake side or well side, the system is identical: a whole-house softener with its brine tank alongside, and a drinking-water faucet on the kitchen sink running on reverse osmosis. Only the hardness setting changes from one supply to the other.
So the setting is the last thing decided, taken from your own faucet's reading, and never the first, taken from a guess about the village.
Common questions
Which water does my Menomonee Falls house get?
It depends on your address. Ask the Village utility with your street address; the plumber's test at your tap on installation day confirms it either way.
How hard is Menomonee Falls water?
Two answers. The lake water the Village buys from Milwaukee Water Works runs 7 to 9 grains. The Village's well water runs 27 to 32 grains, about 462 to 547 milligrams per liter.
Do I need a softener on the lake-water side?
Need is a strong word at 7 to 9 grains, and the choice stays with you. On the well side, at 27 to 32 grains, the case is far stronger.
Is every well-side house at the same hardness?
The Village gives one range for its well water, 27 to 32 grains. Your own reading is taken at the tap before any work begins.
Should I find out my supply before calling?
It helps but is not required. Give us your street address on the call; the Village utility can tell you too, and the plumber confirms it at your tap.
Is all of Menomonee Falls on Lake Michigan water now?
No. Part of the Village system runs on Lake Michigan water purchased from Milwaukee Water Works; wells the Village owns supply the remainder. That split is why it publishes two hardness figures instead of one.
Do you cover Lannon and Butler?
Yes. The Menomonee Falls figures do not describe either village, so a quote there begins with whatever that village's supplier publishes, or with a well report.
Where does the Village publish its hardness figures?
In the FAQ for its water utility. The lake supply is listed there as 7 to 9 grains per gallon, the village wells as 27 to 32.
