Water Backflow Prevention Program
The City of St. Peters has long been committed to public health, safety and environmental compliance. As a water service provider, the City of St. Peters is required by federal and state law to protect the public water supply by implementing and administering a Cross Connection Control (Backflow Prevention) Program. The backflow prevention program requires all connections to the public water supply be equipped with an approved device to prevent water from reentering the public water main. This device must be inspected annually by a backflow prevention tester certified by the Missouri Department of Natural Resources. As the regulating agency, the City of St. Peters is required to maintain a record of these devices and their operating condition.
WHAT'S THIS PROGRAM MEAN FOR PUBLIC HEALTH?
- Backflow prevention devices help protect you and our community by preventing potentially contaminated water from coming back through water supply systems and into your home, business, or the public water supply.
WHEN WOULD A RESIDENCE NEED BACKFLOW PREVENTION?

- Have an approved backflow prevention device. St. Peters Code 705.320 requires that all irrigation systems have a reduced pressure principle backflow prevention device.
