The city term helps discovery. The governing utility still decides the rule, submission method, tester route, and follow-up order.
Aspen annual backflow testing
At least annually, plus on installation and after repair Aspen says initial notifications now come directly from BSI and testers are required to submit reports online through BSI. The city also says containment devices are tested at least annually and residents receive a reminder before the anniversary of the test date.
