Cross Connection Control/Backflow Prevention


Every drinking water system in Iowa must have a cross connection control program, more commonly known as a backflow prevention program. Backflow prevention is designed to protect the public water supply from contamination from customers' plumbing systems. More information regarding the requirements put forth by the State can be found at by clicking here.

Who does this requirement apply to?

Backflow prevention devices are required on all residential properties with irrigation systems. Commercial and industrial businesses also are required to have backflow prevention devices.

Who is managing the Backflow Program?

The Newton WaterWorks has contracted with Backflow Solutions Inc. (BSI) to manage our backflow inspection program. BSI has experience managing similar programs for other municipalities across the country. BSI will serve as the primary point of contact for backflow inspections within the City of Newton and can be contacted at 800-414-4990 or

What are my responsibilities?

It is a requirement that EVERY backflow device be inspected annually by a certified backflow tester. The results of the inspection must be submitted to BSI Online. Backflow prevention inspectors shall submit inspection results to BSI as part of their service provided to you.

How do I comply with these requirements?

Customers with known devices will receive a notification and reminder directly from BSI Online that testing is due. Once the annual inspection is complete, the testing company will enter that information directly into BSI’s online reporting system.

If you have any questions regarding the program please contact LD Palmer with the Newton WaterWorks at (641) 792-2003 or BSI at 800-414-4990.
