Hydrant Flushing

Kaukauna Utilities’ Water Department performs hydrant flushing semi-annually; typically in early spring and late fall. Flushing is done during daylight hours from 7:30 a.m. to 3:00 p.m and takes up to (3) weeks to complete, approximately.

Kaukauna Utilities Customers are advised to check for discoloration prior to washing any clothes. If employees from the Water Department are seen working in the area, please use as little, or if possible, no water for 45 minutes to insure that the water has settled down and that the discoloration is not drawn into the home’s water softener or hot water heater.

Our best advice is to wait until after 4:00 p.m. before washing clothes to minimize potential discoloration. Under certain circumstances, a hydrant being flushed 6-8 blocks away can cause water discoloration. If discoloration persists, customers are advised to wait another 30 to 45 minutes, then draw off the discolored water through the COLD WATER FAUCET ONLY. Flushing will remove most of the sediment of natural minerals such as iron and sulfur that are harmless but yet discolor the water.

We will attempt to keep the inconvenience to a minimum and appreciates the cooperation of our customers during this flushing program.
