Backflow Assembly

To ensure the safety of our community's drinking water, a backflow prevention device is required on inground irrigation systems. This prevents hazardous substances from inadvertently being drawn into the drinking water system, contaminating it. 

All backflow prevention devices must be tested once a year. See a List of Approved Testers  - (updated periodically).

To request a backflow inspection, call 704-391-5188 or email .

For general backflow  questions, please contact Backflow Prevention at 704-432-5800 or 311. ​
