Your backflow prevention assembly device must be in compliance with the Utility's & the State of Tennessee's testing requirements.
It is solely the customer's responsibility to have the device tested annually on or before the date the assembly device was tested from the previous year. Huntsville Utility District will try to send out a courtesy letter or place a phone call to make the customer aware of the due date.
If you have any questions, please call our office at (423) 663-3550.
