The Illinois Environmental Protection Agency (IEPA) requires every community water supplier to develop and implement a cross-connection control program. Part of the program mandates surveying all water customers in their distribution system every three years to identify and eliminate cross-connections that could allow contaminants to flow back into the drinking water from unsafe sources/connections such as fire protection sprinkler systems, boilers, lawn sprinklers and swimming pools.

This survey will be sent regardless of if the water supplier has current inventory of your assembly(s). The current law requires water suppliers to send survey questionnaires to ALL customers.
