Aqua Backflow assists the City with administering its backflow prevention program. Warrenville water customers that have irrigation systems may be notified by Aqua Backflow to ensure compliance. Residential backflow preventers may be found on lawn irrigation systems, wet fire protection systems, hot water heating (boiler) systems, swimming pool fills, and water features. 

Cross Connection Control programs are designed to safeguard public health.  Cooperation with the program is greatly appreciated. More information:
