Wisconsin Utility Connection Costs (2026): Tap Fees by City
In Wisconsin’s two largest cities, a new single-family home with a 5/8-inch meter pays $414 in published connection charges in Madison — a $110 water service application and inspection fee, an $84 water meter charge, a $120 one-time sewer use charge and a $100 sewer connection permit fee — against $615.22 in Milwaukee, made up of a $228 water tap charge, a $267.22 meter extension charge, a $100 DNS sewer/water service piping inspection fee and a $20 plumbing permit processing fee. Neither city charges a citywide water or sewer impact fee on top of that. What each total leaves out is the actual pipe work: the owner separately pays a contractor’s cost to install the water service and sewer lateral, which usually costs more than the published fees themselves. Our database covers Madison Water Utility and Milwaukee Water Works so far. Other Wisconsin utilities are not yet collected, and we say so rather than guess.
Official fees in Wisconsin
The table below lists every verified Wisconsin fee row in our database, with utility, meter size and a link to the source document. Madison and Milwaukee structure their charges differently. Madison bills a water service application fee, a meter charge and a City sewer use charge, plus a separate sewer connection permit fee — and, only where it applies, an area-based Madison Metropolitan Sewerage District (MMSD) connection charge. Milwaukee bills a water tap charge that is keyed to the size of the street main rather than the meter, a meter extension charge, and separate DNS inspection and permit-processing fees for the sewer and water service piping.

City comparison
Published one-time water and sewer connection charges for one new single-family home with a 5/8-inch meter on an infill lot, utility installs both services (sources: Madison Water Utility meter application fee schedule, effective May 1, 2026; Milwaukee Water Works permit charges, effective April 1, 2023, and the codified Milwaukee Code of Ordinances, Chapter 200, Subchapter 5).
| Situation | Madison | Milwaukee | Difference |
|---|---|---|---|
| Infill lot, 5/8″ meter, utility/City installs the connection | $414.00 | $615.22 | $201.22 |
How the rows are built. Madison: $110.00 water service application and inspection fee + $84.00 water meter charge + $120.00 one-time sewer use charge + $100.00 sewer connection permit fee = $414.00. Milwaukee: $228.00 water tap charge (on a 6-inch-or-larger main) + $267.22 meter extension charge (5/8″) + $100.00 DNS sewer/water service piping inspection fee + $20.00 plumbing permit processing fee = $615.22. Milwaukee’s total is $201.22 (about 49%) higher, but both totals are dominated by installation and inspection charges rather than a capacity fee — because neither Madison nor Milwaukee routes a regional sewer-capacity charge through a typical new home’s bill by default, for two different reasons explained below.
Two different MMSDs. Madison and Milwaukee are each served by a regional wastewater agency that happens to share the same acronym — MMSD — but they are separate agencies with different rules, and it’s worth not confusing them. Madison’s Madison Metropolitan Sewerage District charges a one-time, land-area-based connection fee that runs $211.03 to $419.58 per 1,000 square feet of land in 2026, depending on the sewer basin. Unpaid parcels still owe it when they develop, but MMSD’s own guidance says the charge generally must be paid before an area develops, so on most existing Madison lots it was settled years ago or when the subdivision was platted — which is why it doesn’t appear in the $414 infill total above. Milwaukee’s Milwaukee Metropolitan Sewerage District charges no such fee to individual homeowners at all. MMSD’s own site describes itself as a wholesaler that “does not handle direct customer billing” and instead “sends bills to the [member] communities,” with the City of Milwaukee and 27 other member municipalities recovering that cost through everyone’s regular sewer bill. That’s why there is no MMSD line item in Milwaukee’s $615.22 total either — not because it was already paid, but because it is never billed to a homeowner in the first place.

What decides your number
- Meter size. Madison’s total rises from $414.00 to $565.00 with a 1-inch meter instead of 5/8-inch. Milwaukee’s total rises from $615.22 to $644.68 with a 3/4-inch meter instead of 5/8-inch.
- Which water main you tap, in Milwaukee. Milwaukee’s tap charge depends on the street main size, not the meter: $228.00 on a common 6-inch-or-larger main, $252.00 on an older 4-inch main (raising the 5/8-inch-meter total to $639.22).
- Whether MMSD charges were already paid, in Madison. On land where Madison’s regional sewer connection charge was never paid, it’s due on top of the $414 base and varies by basin — for example, an 8,000-square-foot lot in the Nine Springs Valley basin owes an extra $1,818.80 (8 × $227.35).
- Sewer impact fee districts, in Madison. A lot inside one of the City’s sewer impact fee districts, such as Pumpkin Hollow, owes an extra per-square-foot charge on top of the $414 base — $484.80 or more on an 8,000-square-foot lot, in September 2024 dollars that rise each January 1.
- Who pays for the pipe itself. In both cities the published connection fees are small next to the actual cost of the water service line and sewer lateral, which the property owner pays separately at contractor rates. National estimates: $30–$150 per foot for the water line, $50–$250 per foot for the sewer lateral.
Frequently asked questions
How much are water and sewer connection fees in Wisconsin?
It depends on the utility. For a new single-family home with a 5/8-inch meter, published charges total $414.00 in Madison (water service, meter, sewer use and permit charges) and $615.22 in Milwaukee (water tap, meter extension, DNS inspection and permit-processing charges). Neither city adds a citywide water or sewer impact fee on top.
Why doesn’t either city’s total include an MMSD fee?
For two different reasons. Madison’s Madison Metropolitan Sewerage District charges a one-time, land-area-based connection fee, but it’s usually already paid by the time an existing lot is built on. Milwaukee’s Milwaukee Metropolitan Sewerage District — a separate agency that just happens to share the same name — charges no connection fee to individual homeowners at all; it bills the City of Milwaukee and other member municipalities wholesale instead.
Does Wisconsin charge a statewide water or sewer impact fee?
No. There’s no statewide fee; each utility sets its own charges. Madison has no citywide water or sewer impact fee at all (only some sewer districts and unpaid MMSD land add extra charges). Milwaukee has no impact fee either — its published schedule is a tap charge (by main size) and a meter extension charge (by meter size), both one-time charges tied to the physical connection.
Does a larger meter raise connection fees in Wisconsin cities?
Yes, in both cities we’ve checked. Moving from a 5/8-inch to a larger meter adds $151.00 in Madison (to a 1-inch meter, $414.00 to $565.00) and $29.46 in Milwaukee (to a 3/4-inch meter, $615.22 to $644.68).
