Madison Water Utility to start flushing water mains this week

Madison Water Utility crews will be flushing water mains this week, according to a release.

Every year during the warm weather months, MWU crews complete maintenance work on the city’s water mains using a technique known as unidirectional flushing, officials said. The aggressive flushing technique moves water at a high velocity through water mains and fire hydrants to clear out sediment from naturally-occurring minerals.

Clean pipes are important for a clean, healthy water supply, and that’s why MWU works to maintain the pipes with this flushing process, according to the release.

Flushing water mains can temporarily cause discolored water in nearby homes while crews are working, officials said. If residents notice flushing signs in their neighborhood, wait until later at night to do laundry or run the dishwasher, and make sure water is clear before using it. If residents do experience discolored water, officials suggest running a tap in the basement for a few minutes until the water becomes clear again.
