Some public water system customers are required to have and maintain backflow assemblies on certain types of water lines according to the Missouri Department of Natural Resources (MoDNR) Drinking Water Program regulation. The regulation also requires annual inspections by a certified backflow inspector.
The Water Department mails courtesy advanced notification letters for all testings coming due. Those customers with the following service lines are required to have their backflow assembly tested:
- Commercial water lines
- Fire lines
- Irrigation systems
- Dock-supplied water lines
- Other service lines as noted by the Missouri Department of Natural Resources
Contact the Water Department or the Missouri Department of Natural Resources for more information regarding backflow prevention and testing.
