Protecting potable water
Cross-Connection & Backflow Prevention Program
Mattoon operates a Cross-Connection Control Survey to identify potential plumbing connections that could allow contaminated water to enter the City’s potable water system during a low-pressure event.
Customers provide information about plumbing conditions that can create a back-siphon risk.
RPU-style RPZ/backflow devices are not self-certifying; Mattoon says required devices must be tested by a Cross-Connection Control Device Inspector.
The City states that required backflow prevention devices such as RPZs must be tested when installed and at least annually thereafter by a qualified Cross-Connection Control Device Inspector.
Customer plumbing information
Mattoon IEPA Lead & Copper Survey
The City’s current Utilities page provides an IEPA Lead and Copper Survey for water customers.
The survey gives the City information relevant to water-service and plumbing materials. Use the official City form rather than assuming the material of a service line based only on a home’s age.

This guide separates Finance Department customer-account functions from Public Works water-system operations. That distinction prevents customers with a bill problem from being routed to the Water Treatment Plant and customers with a main break from being routed only to billing staff.
The current City Water Rates link was also reviewed. Because the rate document available through the City’s site is labeled 2025, this article does not incorrectly present those values as newly adopted 2026 rates.
