Water softener installation in New Berlin, WI
About 8 grains per gallon on city water, 18–32 on old city wells · New Berlin’s published figures
New Berlin is two water towns. If you are on city water it changed in 2009 and the utility says you should no longer need a softener. If you are on a well, nothing changed at all.

Where New Berlin gets its water
New Berlin is served by the New Berlin Water Utility, which buys all of its water rather than treating any. The city system has run on 100% purchased Lake Michigan water from Milwaukee Water Works since July 2009. Homes on private wells draw county groundwater instead.
City water is purchased lake supply at about 8 grains. Private wells draw the groundwater the city used to pump.
Milwaukee publishes its Lake Michigan supply at 137 milligrams per liter of hardness across a 112 to 142 range, which is about 8 grains per gallon; New Berlin’s own literature puts it at 8 to 10. The utility’s published figure for the groundwater it used to pump was 18 to 32 grains, and homes still on private wells are drawing from that same aquifer today.

$3,950 installed for the ZeroGrain One: softener, activated carbon and the reverse-osmosis drinking tap. Installation by an independent licensed Wisconsin plumbing contractor is in that number, not added to it, and the date is set once the equipment is in hand and approved for use in Wisconsin (SPS 384). What a softener costs explains what the $3,950 includes. Swapping out an old unit is replacing a softener; the drinking tap is reverse osmosis installation.

Questions
New Berlin water questions
Anything that is not here, ask it on the call.
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.
A utility talking its own residents out of buying equipment
The New Berlin Water Utility is unusually direct: it tells customers they should no longer need a softener. That is worth taking seriously, and we are not going to argue with it. Eight grains still sits in the USGS “hard” band, so glasses spot and a heater still scales over ten years, just more slowly. What genuinely changed is the priority: on the city side, softening is optional rather than obvious, and the call tells you plainly whether the whole-home system, RO tap included, is worth it.
If your softener predates 2009, it is probably set wrong
It is almost certainly still dialed for 20-plus-grain well water, which means it regenerates far more often than it needs to and wastes salt every week. That is worth correcting whether or not you ever buy anything from us. On the well side nothing has changed: 18 to 32 grains, often with iron, is the classic southern Wisconsin well profile and it is what softening was built for.
How does the quote work in New Berlin?
We start from the number, not from a catalog: what New Berlin publishes, and what your house needs. One short call puts the two together, at no charge. If the numbers justify softening we size it from them; if they point away from softening, the call says so plainly. On install day the plumber reads hardness, iron, chlorine and TDS at your tap before anything is connected, and on a softener install retests hardness at the end so you watch it read zero.
