Germantown, Washington County
Germantown water, by the numbers
Germantown publishes one of the highest municipal hardness figures in the region: 24 grains as a six-well average. There is no lake water in this system and no plan to add any.
Where Germantown’s water comes from
Germantown is served by the Village of Germantown water utility. It pumps six municipal wells, all groundwater.
The Village publishes a combined average across all six of its wells.
The Village publishes hardness of 24 grains as a combined average across all six of its wells. That is among the hardest published municipal figures in southeastern Wisconsin, and more than three times the lake-water suburbs twenty minutes east.

A combined average across six wells is worth reading carefully
A six-well average is a useful headline and not the same as the number at your street. Individual wells in a system this size can sit either side of the mean, which is the ordinary reason a utility average and a tap reading disagree.
At twenty-four grains the salt bill is the argument
This is the hardness bracket where the gap between a demand-metered softener sized to a real measurement and a timer-based unit sold off a shelf shows up every month in salt. Sizing from your measured hardness is the version of this equipment that uses the least of it.
What we would actually do here
The same thing we do everywhere: read your tap before recommending anything. Hardness, iron, chlorine and TDS, on the spot, in front of you, at no charge. If the numbers justify softening we size it from them; if they point at a drinking-water tap instead, that is what the quote says. On a softener install we run the same test at the end and you watch it read zero.
Softening removes hardness minerals. It is not a health or safety treatment and we do not market it as one. On a private well, Wisconsin’s state-certified lab tests for bacteria and nitrates are a separate matter and not something we sell.
