Madison Water Utility Flushing Water Mains

The Madison Water Utility will be flushing water mains on and around campus overnight this week between 10pm and 5am.

This pressure change sometimes stirs up mineral sediment in nearby water mains, causing discolored water. The minerals that most often lead to discolored water in Madison are iron and manganese, which naturally occur in our sandstone aquifer.

If observed, this can be resolved by:

  • Run the cold water tap until the water runs clear.
  • It helps to turn the cold water tap on all the way, flushing the discolored water out as quickly as possible.
  • If your water does not clear after 5 to 10 minutes, call Physical Plant Customer Service at (608) 263-3333.

While discolored water is not harmful, we generally recommend that people avoid using it for cooking or drinking.
