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.

Middleton Water Utility Customers

The City of Middleton Water Utility will be performing our routine spring flushing of mains and hydrants throughout the City beginning on Sunday night, March 29th, and ending on Thursday morning, April 9, between the hours of 7:00 pm-5:00 am.  A slight discoloration of the water may be noticed during this time period.  If you notice a rusty color in the water, running it for a few a minutes usually helps clear it up.  Residents may also receive notifications through the "Notify Me" option for updates on areas scheduled to be flushed and additional information.  Your cooperation and indulgence is appreciated. 

Also, 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.
