Diggers Hotline

Call 811 before you dig!


Kaukauna Utilities would like to remind you that when you are planning projects that require any digging, there may be underground utilities that could be affected. Please, plan ahead and call Diggers Hotline before you dig to have utilities located and marked. Calling 811 is a new FCC-designated national N-11 number created to help simplify contacting one-call centers across the country. This quick and efficient service will notify the appropriate utilities, who then send to the requested site to mark the approximate location of underground lines.


Electrical Problems: For electrical problems such as a power outage, flickering lights, downed power lines, or other problems related to electrical power service to your home or business, call us at 920-766-5988.

Water Service Problems: For problems with water service such as a broken water main, loss of water pressure, or questions about water quality, call us at 920-766-5988.
