Brookfield water hardness
Brookfield has two published hardness figures, one from the City of Brookfield Water Utility and one from the Town of Brookfield’s Sanitary District No. 4. Both describe very hard water, and which one is yours depends on your address.

Who supplies Brookfield’s water
City homes are served by the City of Brookfield Water Utility, which pumps municipal wells inside the city limits and buys no Lake Michigan water. Town of Brookfield homes on public water are served by Sanitary District No. 4, which runs a separate system.
The city’s figure: 23 to 34 grains
The city’s water-quality FAQ gives its water as 23 to 34 grains per gallon. In the units a lab report uses, that is about 393 to 581 milligrams per liter.
The city’s chloride-reduction guidance adds a single number to that range: it asks residents to set softeners to 23 grains, the low end of what the city publishes.
The Town’s figure: 32 to 35 grains
Sanitary District No. 4 publishes 32 to 35 grains for the Town’s system. Its low end sits near the top of the city’s range, and its high end goes one grain past it.
The 23-grain setting comes from the city, for city water. A Town house on the district’s system starts from the district’s own figure.
Very hard at either end of the range
Past 10.5 grains, which is 180 milligrams per liter, the USGS calls water very hard. Beneath that line sit hard water (121 to 180), moderately hard water (61 to 120) and soft water (60 or less).
Brookfield’s lowest published figure, the city’s 23 grains, is more than twice the very hard line. The district’s 32 to 35 is more than three times it.
Matching your address to the right Brookfield figure
The address tells you which system you are on, and the water bill names the utility. With no water bill, the house most likely has a private well, and its lab report carries its number; 17.1 milligrams per liter make one grain.
During the call, the quote for a city address begins with the city’s figures, a Town address with the district’s 32 to 35, and a house on a private well with the hardness its lab measured. The plumber’s first job on install day is a test at your tap, and the last is a retest that reads zero.
Common questions
Is Brookfield’s water among the hardest in Waukesha County?
Yes. Brookfield stayed on its own wells while several neighbors moved to Lake Michigan water, and its published range of 23 to 34 grains reflects that.
What is 23 grains in milligrams per liter?
About 393, the bottom of the city’s published range. To go from grains to milligrams per liter, multiply by 17.1.
