Service flushing. The water service to Middleton High School, off of Lee & Clark St., will be flushed by a private contractor on Wednesday, April 22nd, between 8:00 AM and Noon. A slight discoloration of the water may be noticed during this time.If you notice a rusty color in the water, running it for a few minutes usually helps clear it up. Your cooperation and indulgence is appreciated. Thank you.
