Utility service in Wisconsin works as a patchwork rather than a single system. The company that bills you for electricity depends on your address, not on a choice you make. Your water may come from a city department, a sanitary district, or a well in your own yard. This page explains who runs each service, how the state oversees it, and which office to call first.

The listings in our directory range from large city water departments in Milwaukee to small cooperative offices in towns such as Westby, Alma and Cumberland. Knowing which type of organisation you are dealing with saves time, because each follows different rules for billing, complaints and outages.

How Utility Service Is Divided Across Wisconsin

Most Wisconsin utility offices fall into one of four groups. The group decides who owns the system, who sets the rates and where you take a problem.

Some listings are less obvious. Green Bay City Parking Utility, at 100 North Jefferson Street, is run as a city utility even though it deals with parking rather than power or water. North American Hydro in Beloit has a name that suggests a hydroelectric business, not a customer service counter. Check what a listing actually does before you drive there.

Who Regulates Utilities in Wisconsin: PSC, DNR and Local Boards

The Public Service Commission of Wisconsin, headquartered in Madison, is the main state regulator. It acts under Chapter 196 of the Wisconsin Statutes. The commission reviews rate requests from investor-owned electric, gas and water companies, and it approves major construction projects such as new power lines.

Wisconsin goes further than many states. The commission also reviews rates for municipally owned water, electric and gas utilities. A city water department that wants to raise its rates normally files with the commission, and customers can submit comments. Electric cooperatives work differently. Their boards, elected by members, set rates, and members vote at annual meetings.

Water quality falls to a separate agency. The Wisconsin Department of Natural Resources oversees public drinking water systems and issues discharge permits under the Wisconsin Pollutant Discharge Elimination System. A plant such as the Appleton Wastewater Treatment Plant on East Newberry Street operates under one of those permits and reports its results to the state.

Private wells and septic systems sit outside the utility model. Owners of private wells are responsible for testing their own water. Septic systems follow state plumbing rules and are usually administered through county offices. In rural counties, this affects a large share of households.

One more rule applies everywhere. Before any digging project, call 811 to reach Diggers Hotline, the state's one-call service. Utilities then mark buried lines at no charge. Hitting a gas or electric line can cause injury and large repair bills.

City Utilities Versus Rural Cooperatives in Wisconsin

Where you live changes the experience more than anything else. In the large cities, one department often handles water, sewer and stormwater on a single bill. Milwaukee Water Works, at 841 North Broadway, draws water from Lake Michigan and serves Milwaukee and several neighbouring communities. You can reach it at 414-286-2830. Other offices in Milwaukee County have their own page.

Dane County has the most listings of any county in our database. The Citizens Utility Board sits at 16 North Carroll Street in Madison. It is a nonprofit consumer group that speaks for ratepayers in cases before the state commission, so it advocates for customers rather than billing them.

The Fox Valley shows a different pattern. Appleton, in Outagamie County, has more listings than any other city. Nearby Menasha adds several more, including the Waverly Sanitary District in Winnebago County. Dense urban areas like these pack many small, specialised offices within a few miles of each other.

Farther east, Green Bay and De Pere sit side by side in Brown County. De Pere Energy Center, at 112 North 5th Street, is one of the offices there. In southern Wisconsin, Janesville Utility Billing at 18 North Jackson Street (608-755-3090) handles customer accounts, and neighbouring Beloit has its own set of listings. Both cities are covered on the Rock County page.

Rural Wisconsin runs largely on cooperatives. Barron Electric Cooperative's office is at 1434 Wisconsin 25 in Barron. Vernon Electric Cooperative operates from Westby, and Riverland Energy Cooperative from Alma. Cooperative lines cover long distances with few customers per mile, so storm outages can take longer to fix than in a city. Members also receive capital credits, which return a share of the cooperative's margins over time based on how much power they used.

Small-town municipal utilities fill the gaps between. Medford Electric Utility, at 639 South 2nd Street, serves the Medford area in Taylor County. The Boscobel Utilities Office handles accounts in Grant County. Many offices like these keep standard weekday hours, so call ahead before you visit.

Practical Steps for Starting, Moving or Disputing Service in Wisconsin

Start by confirming your provider. Ask your landlord, check your property tax bill, or call the city or village clerk. Electric and gas service areas are generally fixed, so a street address usually points to one provider. Wisconsin does not offer retail electric choice to households.

When you call to open an account, have these ready:

Some utilities ask for a deposit when your credit history is thin. Ask what the amount is and how it is refunded.

Know the billing rules before the first bill arrives. Many Wisconsin municipalities can add unpaid water and sewer charges to the property tax bill, which matters most to owners of rental property. Winter brings extra protection: between November 1 and April 15, the state's cold weather rule limits disconnection of heating service for residential customers. Ask your utility about payment plans before you fall behind.

Timing also helps. Due dates often cluster at month-end, so phone lines are busiest then. Calling mid-month usually gets you through faster. Report outages to your own provider, not to the state, because only the utility can dispatch a crew.

If a problem is not resolved, escalate in steps. Begin with customer service, then ask for a supervisor, then contact the commission's consumer affairs staff, who take complaints about regulated utilities. For a cooperative, you can also raise the issue with your elected board. Keep dates, names and copies of bills.

Municipal utility departments throughout Wisconsin provide electricity, water, sewer, and related services to millions of residents and businesses. Utility governance in Wisconsin is shaped by the state's public utility commission, which regulates investor-owned utilities, while municipally owned systems operate under local authority.

Utilities locations are available in 174 cities across Wisconsin. They are spread across 67 counties.

Cities with the highest concentration of utility offices include Appleton, Milwaukee, La Crosse, reflecting their larger populations and service area demands.

Wisconsin residents should contact their local utility provider directly for account setup, billing questions, and outage reporting. State-level utility assistance programs may also be available through the state's health and human services agency.

Utility Offices Beyond the Big Cities in Wisconsin Counties

Many of the most useful offices in the state sit in small cities. Tomah Water and Sewer Utilities, at 819 Superior Avenue, handles both services for Monroe County customers from one counter (608-374-7433). In the far north, the City of Ashland Water & Wastewater Utility on Knight Road manages systems on the Lake Superior shore. A single office covering water and sewer is common in smaller communities.

Cumberland Utility Electric, at 1265 2nd Avenue, is one of several offices in Barron County. The county's listings are split between cooperative and municipal providers, so two neighbours can receive bills from different organisations. Always confirm which one serves your exact parcel.

Oconto Electric Cooperative keeps its office at 7479 Rea Road in Oconto Falls. Arcadia Municipal Electric Utility is at 115 Jackson Street in Trempealeau County. Jackson Electric Cooperative is at N6868 County Road F in Black River Falls. Addresses like these can be hard to find, so check the street and hours by phone first.

Sanitary districts add another layer. The Waverly Sanitary District lists County Road LP in Menasha, and the Rib Mountain Sanitary District is at 5703 Lilac Avenue in Wausau. These special-purpose districts are created under state law, governed by commissioners and funded by their own sewer charges. If you live just outside a city boundary, your sewer bill may come from a district rather than from the city.

Before you visit any office, bring a photo ID and a recent bill. If you are a tenant, bring your lease so staff can confirm who is responsible for the account.

Start with the utility's customer service line and ask for a written explanation of the charge. If that fails, ask for a supervisor. Customers of regulated gas, electric and water utilities, including many municipal systems, can then file a complaint with the Public Service Commission of Wisconsin in Madison. Its consumer affairs staff contact the utility and review the dispute. Electric cooperatives answer mainly to their member-elected boards, so you can raise the issue with a director or at the annual meeting. Keep copies of bills, dates of calls and the names of people you spoke with.

Generally, no. Wisconsin has not opened residential electricity to retail competition, so your address determines whether service comes from an investor-owned company, a municipal utility or a cooperative. Large cities usually have one provider, and rural areas are served by the cooperative whose lines run past your property. If you move, ask your landlord or the village clerk which utility serves the new address, then call that office to open an account. Some larger natural gas customers can buy gas from outside suppliers, but this rarely applies to a typical household.

Wisconsin has a cold weather rule that runs from November 1 through April 15. During that period, a utility generally cannot disconnect residential heating service without following extra steps, such as offering a payment arrangement and allowing for medical emergencies. The rule does not erase what you owe, and charges keep accruing. Call your provider as soon as you fall behind and ask about a deferred payment plan. Procedures can differ slightly between investor-owned, municipal and cooperative utilities, so confirm the details for your own account directly with the office that bills you.

The Wisconsin Home Energy Assistance Program, known as WHEAP, helps eligible households with heating and electric costs. The state Department of Administration oversees it, but you apply through a local agency that serves your county. Expect to provide photo ID, proof of income for everyone in the household and a recent energy bill. Dialing 211 can connect you to the nearest agency. Separately, Focus on Energy, the statewide efficiency program, offers rebates for insulation and efficient equipment that can lower future bills. Check current income limits and deadlines with the agency, since they change.

Call 811 or submit a request to Diggers Hotline at least three working days before you dig. Utilities with buried lines in the area will mark them with paint or flags, and the service is free. Wait for all markings before breaking ground, and dig carefully near them. This applies to homeowners as well as contractors. Striking a gas or electric line is dangerous, and you may be responsible for repair costs. Rural properties often have private lines, such as a well pump cable, that utility crews do not mark, so know where yours run.

If you use a municipal or sanitary district water system, the Wisconsin Department of Natural Resources oversees it, and your system publishes an annual water quality report. If you have a private well, nobody tests it for you. Owners are responsible for sampling, and your county health department can explain which tests matter and refer you to a state-certified laboratory. Testing for bacteria and nitrate is a common starting point in farm country. It also makes sense after a flood or after any change in the taste or smell of your water.
