Water Main Flushing

We're flushing water mains!

View the interactive Chaska Hydrant Flushing Map to see when the Water Department will be in your neighborhood. Click on the sections of the map to see if flushing has been completed.

Flushing water mains helps maintain water quality and prevent sediment buildup within the pipes. This process also provides crews an opportunity to operate and inspect the fire hydrants.

If you notice air in your water lines or discoloration in your water, open up a cold tap closest to your water meter (typically in a mechanical room), and allow water to run for 5-15 minutes. While discolored water is OK to drink, wait to do laundry until the discoloration is gone. 

If you have any additional questions or concerns, please contact the Water Department at 952-448-4335.
