Backflow Prevention

Cross Connection/Back flow Prevention


When drinking water piping connects to various plumbing fixtures or water utilizing equipment a cross-connection is created. If improperly protected, contamination can result when a backflow event occurs; allowing contaminates to reverse flow from the fixture/equipment back into the drinking water piping.

Kaukauna Utilities is pleased to announce that it has contracted Hydro Designs, Inc. of Brookfield, WI to assist with the implementation of a Cross Connection Control Program. This program is designed to inform you the customer about existing or potential cross connections that may exist in your business or home internal plumbing system. The Utility’s goal is to provide you with a safe and dependable supply of drinking water. We want you to understand the efforts we make to continually improve and protect your drinking water resources. We are committed to ensuring the quality of your drinking water.

A cross connection is a direct or a potential arrangement of drinking water piping that is or can be connected to a questionable source. An example is the common garden hose attached to a sill cock with the end of the garden hose submerged into a bucket of detergent. Other examples may be your home’s underground lawn sprinkling system or water treatment unit. Examples of commercial cross connections may be found on carbonated beverage equipment, boilers and process equipment.

In order to maintain a safe and dependable drinking water supply,  KU requires improvements to our customer’s internal plumbing. We ask that all our customers help us protect our drinking water supply by participating in the cross connection control program and the upcoming KU efforts to increase the awareness of cross connections. Thank you for allowing us to continue providing your family with clean and safe drinking water.

We want our customers to be informed about their potable water. If you have any questions about the program or any concerns, please contact:
