ST. CHARLES – All St. Charles water customers are required to complete the Biennial Water Use Survey conducted by Aqua Backflow.
The survey is required every two years by the Illinois Environmental Protection Agency, the Illinois Plumbing Code and city ordinance. The information obtained is used to ensure safe drinking water for all users by documenting whether a homeowner has certain devices, such as a lawn irrigation system or whether a backflow prevention device is installed on the internal water system.There is no deadline for the survey, but reminders will be sent to follow up on unreturned surveys.
Residents may fill out the card that was mailed and return it to the address noted on the survey. Surveys also may be dropped off at City Hall or the Public Works facility. The form may be faxed toll-free to 866-777-2125.
An online option also is available. Visit www.aquabackflow.com, click on the Forms tab, enter the password “stc” and complete the appropriate survey.
Call the St. Charles Public Works Department at 630-377-4405 or Aqua Backflow toll-free at 866-777-2124 for information.
