About the Water & Sewer Utility

The City of Middleton Water and Sewer Utility is responsible for maintaining approximately 160 miles of water and sewer mains. We have eight water pumping stations with a combined pumping capacity of over eight million gallons per day and nine sewer pumping stations that pump to the Madison Metropolitan Sewerage District. Middleton serves about 6,000 metered customers with an average daily use of 2.3 million gallons per day. We also maintain over 900 hydrants and 1,500 valves.

The Water Utility has two water towers with a combined capacity of 1,250,000 gallons and two ground reservoirs that hold 1,100,000 gallons. Middleton draws its water from six sandstone wells, ranging in depth from 330 feet to 856 feet. These wells penetrate the Franconia, Galesville, Eau Claire, and Mount Simon formations. The Water and Sewer Utility are a self-supporting enterprise with 100% of the expenses paid by the utility customers through quarterly bills.

Fall System Flushing
The Middleton Water Utility will be flushing mains and hydrants throughout the City during the weeks of Sept. 13-17 and Sept. 20-24, between the hours of 7:00 pm – 5:00 am. A slight discoloration of the water may be noticed during this maintenance. If you notice a rusty discoloration in the water, running it for a few minutes from a lower level faucet helps clear it up. Your cooperation and  indulgence is appreciated. Thank you.

Emergency Order #11
Please be aware that on March 22, 2020, Governor Evers exercised his authority under Wis. Stat. 323.12(4) (d) and issued Emergency Order #11, temporarily suspending certain provisions of Wis. Admin. Code Chapters PSC 113, 134, and 185 relating to service rules for electric, natural gas, and water public utilities.  As detailed in the Governor's Emergency Order, the specific provisions include:

  • Authorize public utilities to waive late fees.
  • Temporarily suspend disconnections, other than those needed for safety reasons.
  • Enable customers who are unable to make a cash deposit to obtain residential service.
  • Ensure that deferred payment agreements are available not only to residential customers but also commercial, farm, and industrial customers.
  • Streamline the process for customers to apply for utility service.

Thank you.

Stagnant Building Water

Middleton Water Utility and Public Health Madison & Dane County are warning people about the danger of stagnant water in buildings that have been closed during the Coronavirus (COVID-19) pandemic. Water in plumbing that has been sitting stagnant for weeks could be a breeding ground for bacteria and potential pathogens like Legionella.

Buildings across the city and state have been at reduced capacity or closed as people stay home to limit the spread of the virus. Now, some businesses are starting to re-open under the Governor’s new Safer at Home Order guidelines. But it’s crucial that people pay attention to their plumbing and make sure the water is safe.

Public Health has put together a guide PDF  to help businesses and other buildings re-open safely. Stagnant water will have to be flushed from both the hot and cold water systems in a building to get fresh, chlorinated water in.
