Celebrate National Drinking Water Week, May 7-13 2017Celebrating Clean Water

Drinking water 101

Learn more about the water you drink -- everything from the molecules that form this amazing liquid, to the many different ways it powers our economy and businesses, to how much water it takes to make a hamburger, fries and a soda.

Drinking water fast facts

  • Wisconsin has more public water systems than any other state in the nation. Public water systems serve at least 25 people at least 60 days of the year.
  • Wisconsin communities, businesses, farms, utilities and other users withdrew about 1.95 trillion gallons of water in 2014, enough to cover the surface of Wisconsin in roughly two inches of water.
  • Wisconsin residential customers on average use 55,100 gallons per year. Average usage has declined 6 percent since 2007.
  • Wisconsin residents pay on average $5.50 for every 1,000 gallons of tap water - mere fractions of a penny per gallon.
  • Wisconsin's community water systems and not-for-profitnon-community water systems will need to invest an estimated $7.141billion by 2031 to continue to provide safe and adequate supplies of drinking water.

Celebrate safe drinking water

Every day millions of Wisconsinites experience something amazing and likely never think twice about it. We turn on our faucets, drink from a water fountain, or brew beer and without effort are provided with safe drinking water.

That's remarkable in a world where 1 billion people still must walk on average 3.5 miles to get water, and don't know if it's safe to drink. That's why we celebrate National Drinking Water Week every year.

Raise your glass

We owe our safe drinking water to the men and women who work behind the scenes to deliver it to us -- local waterworks operators, public utilities, county health officials, state drinking water and groundwater staff, association staff, testing laboratories and consultants, to name a few.

Let's raise a glass to recognize their efforts, and show our appreciation for the convenience and assurance their work brings to our daily lives and businesses.

What's in my water?

Wisconsin is viewed as a national model for the amount and accessibility of drinking water information provided to water consumers. Check out these resources for the statewide picture - or to zero in on your own water supply.

Drinking water and lead

Lead can enter drinking water through the corrosion of your home's plumbing materials and water lines connecting your home to a water main. For more information about how you can protect yourself and your family, visit the drinking water and lead webpage.

Where does my water come from?

Two-thirds of Wisconsin residents get their drinking water from groundwater. One-third of Wisconsin residents get their drinking water from surface water supplies such as Lake Michigan, Lake Superior and Lake Winnebago.

How do we use water?

Operations that withdraw more than 100,000 gallons of water a day are required to report their usage and are starting to give Wisconsin important information on how much water we collectively use. See the breakdowns by major uses.
