State and federal regulations require the devices be tested and inspected at least annually in accordance with the city’s cross connection control program. Maryville Municipal Code requires that irrigation backflow devices be installed and have water service up to the No. 2 shutoff valve of the backflow device no later than May 1 of each year and remain in service until Sept. 30 to allow for required annual inspections and tests.
Devices not installed or not in service will result in return trips and re-inspection fees assessed to the customer’s utility account.
Questions can be directed to the Water and Sewer Department at 865-273-3304 from 7:30 a.m. to 4 p.m. Mondays through Fridays.
