Tri-Township Water District

Trenton, Illinois

Cross Connection Control 

Tri-Township Water District is required to implement an active cross-connection control program. A cross-connection is any situation that allows a potable (safe) water source and a non-potable (contaminated) water source the opportunity to come into contact with each other. The Illinois Environmental Protection Agency (IEPA) and the Illinois Department of Public Health are responsible for ensuring that cross-connections do not occur through the enforcement of cross-connection control regulations. A cross-connection between potable and non-potable water sources may cause anything from contamination of plumbing to sickness and even death in consumers.

This program is a survey of all consumers served by our public water supply. Below is a survey you need to complete and return to Tri-Township Water District office every other year. Simply mark all plumbing fixtures that you have in your home or business. If you have other fixtures that are not listed please mark in the “Other” spaces.

After we receive your survey we will review the data and determine if any inspection of your plumbing is needed. If it requires an inspection you will be notified by mail.

*These surveys are required by the IEPA and must be completed.  If Tri-Township does not receive your completed survey, the District does have the option to discontinue service due to possible threat of contamination to the Public Water System.
