How do I obtain information on the city’s backflow control program?
The backflow control program is an annual inspection program under which certain COA water customers must obtain annual inspections. This is to ensure that their water system is free of cross-connections, which could provide an entry point for contamination. Common examples of such users include commercial buildings with hot water boilers or fire suppression systems, and users with permanently installed underground irrigation (sprinkler) systems. To obtain further information, please contact Daryl Devick, Assistant Director of Public Works, at 630-256-3200.
