Sussex, Waukesha County
Sussex water, by the numbers
Sussex sits in the middle of the county range: harder than anything on lake water, softer than Brookfield or Germantown. Middle of the range still means every gallon through your heater is carrying seventeen and a half grains of dissolved rock.
Where Sussex’s water comes from
Sussex is served by the Village of Sussex water utility. Its municipal wells draw Waukesha County groundwater.
300 mg/L as calcium carbonate, which is 17.5 grains per gallon.
The utility publishes total hardness of 300 milligrams per liter as calcium carbonate. Divided by 17.1, that is 17.5 grains per gallon, comfortably into the USGS “very hard” band, and roughly double what the lake-water suburbs on the other side of the county line run.

Middle of the range is not mild
Seventeen grains is roughly twice the USGS threshold for “very hard.” The scale on a heating element does not care that a town down the road reads thirty. What it responds to is the number at your tap, multiplied by every gallon you have used since the unit was installed.
Where iron enters the conversation
Sussex sits in the part of the county where iron commonly travels with hardness out of the same rock. On the municipal system that is the utility’s problem; on a private well it is yours, and it changes what the system has to be. The quote visit reads iron alongside hardness for exactly that reason.
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.
