The Middleton Water Utility will be flushing mains and hydrants throughout the City during the weeks of Sept. 10- 14 and Sept. 17-21, 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.
