The Illinois Environmental Protection Agency (IEPA) requires that all water systems in the State of Illinois have an effective Cross-Connection Control Program. Cross-connections within the public water supply are a serious concern, as they can allow contaminants or pollutants to enter the public water system through what is called “backflow.” Backflow occurs when a drop in water pressure causes your water to flow in the opposite direction, allowing contaminated or polluted water to flow back into your drinking water. Given IEPA regulations and the dangers that exist from unprotected cross-connections, it is necessary to establish and maintain an effective cross-connection control program to protect both the integrity of the City of Palos Hills’ water supply as well as its water customers. For more information on cross-connections, review this EPA Fact Sheet (PDF).

The City of Palos Hills requests the community’s help in identifying where cross-connections exist within the City. Please take a moment to complete the brief survey that was included within your water bill and return it to City Hall, located at 10335 S Roberts Road, Palos Hills, IL. Your cooperation in this critical program helps the City further protect our water from potential contamination. Thank you for your assistance!
