Delafield waterworks or a private well: which is yours?
In Delafield the answer is not obvious from the street. The city says most residents have private wells and its waterworks serves the minority, and the City and the Town of Delafield sit side by side under one name.
Call (262) 829-5961Mon to Fri, 7am to 5pmWhy it matters before you call
The two supplies come with different numbers. On the waterworks, the DNR's same-day samples of the city's two wells, 240 and 400 milligrams per liter, give the range. On a private well those samples say nothing about your water, and only a test of your own well can supply the figure.
Signs of a private well
A private well has parts the city system does not: a well cap somewhere on the property, and usually a pressure tank near where the well line comes into the house. A home with those, and no water bill from the city, is on its own well.
Given what the city says about most of its residents, a well is the likelier answer in Delafield, but it is worth confirming. Sellers, past owners and the home's paperwork can do that, and a house on a well may have old lab reports tucked away somewhere.
Signs of the city waterworks
A home on the waterworks pays the city for its water, and the service line usually comes in from the street through a water meter. If you are not sure, the City of Delafield's utilities page is the place to start, since the city runs the system.
A waterworks home usually has no well cap in the yard and no pressure tank where the line comes in, which is the same test run from the other side.
City or Town: the name does not settle it
An address in the City of Delafield can still be on a private well; the city says most of its residents are. The Town of Delafield is a separate municipality from the City, and the waterworks figures describe the city's two wells only.
So neither the municipality on your tax bill nor the Delafield in your mailing address answers the question by itself. The pipe coming into the house does.
What to say on the call
Start with which one you have, or that you are not sure. City customers can stop there for water figures; well owners should have the lab report's hardness line and its date ready.
Either way, the plumber's reading at the tap on installation day comes before anything is connected, and it settles the starting number for the softener.
Common questions
We're on a well, but our neighbors have city water. Can we use their figures?
No. Their figures belong to the city's two wells, which themselves read 14.0 and 23.4 grains on the same day. Your well needs a number of its own.
What if we can't tell which supply we have?
Say so on the call. The questions about the house usually sort it out, and the reading at your tap on installation day gives the hardness either way.
