Water supply

Permit Primer

When starting a small business, you will need to consider all of your water needs. This can include any basic services such as restroom facilities (toilets, sinks, showers), breakrooms (coffeemakers, sinks) or fire suppression (sprinkler systems, standpipes) to process water needed for complex business operations.

Once you have identified your water needs, you need to explore what your water source will be. Will you be able to hook up to a municipal water system or will you need to install a new well? This section of the primer will help you work through those questions as well as offer you information on water saving techniques, appropriate permits and staff contact information.

Water conservation information for municipalities

When working with your local community on obtaining water, now is a good time to consider how much water you will need and the ways in which you can conserve water to save money. Many Wisconsin residents and businesses consider clean water to be an unlimited resource. But, in fact, our state's water supply is an exhaustible natural resource. To ensure sufficient water supplies for present and future generations, we must use this precious resource wisely. By effectively managing your water usage (for example using aerating faucet inserts or low flow showerheads) your small business can help increase the life of existing water supplies, minimize the impact of drought, and delay or minimize additional development.

By conserving water you can also have a significant effect on local water demands. And, in addition to the environmental benefits, your water efficiency programs will reduce costs and increase the profitability of your business through:

  • water and sewer cost savings;
  • wastewater treatment cost savings; and
  • energy savings.

Furthermore, as water quality regulations become stricter and the cost of water increases, your wise use of water will help you gain an edge over your competition.

No DNR water supply permits are required when hooking up to a municipal water supply. Please contact your municipality and refer to the "Municipality information/Common questions" below for detailed information.

Municipality information/common questions

When hooking up to a municipality's water supply, the first question you'll want to ask yourself is, "Is there a water main?"

Check with City Hall or your city's water plant to determine if a water main runs near your proposed or existing business site. In most cases, the city will set up a water line from the water main to the curbside for a flat fee (usually includes a water shut–off valve at the curb and lifetime maintenance).

Who will I need to hire to set up my water supply system?

You will probably need to hire a licensed plumber to dig a trench (from water main to proposed or existing building), and install a water line from the curbside to the building. A one-inch line is typical for businesses needing showers, toilets, sinks (e.g. gas station, tavern, etc). If you need a larger diameter water line (higher flow? amount? water needs) you will need to coordinate this between the city and the plumber to ensure consistency. NOTE: Costs may increase as many municipalities charge time and materials when higher water usage is desired (see the "Water conservation information for municipalities" above for ways to reduce your water needs and save more.)

Do I have to connect to the public water supply?

According to state statute, it may be mandatory that you hook up to the city water supply if a water main exists at your business location.

If you are going to need over 70 gallons per minute, you will need to apply for a high capacity well permit. Please download the high capacity supply wells application and submit it per the directions. Licensed well drillers are able to obtain and assist you with filing the application.
