Why Gilbert maps to Town of Gilbert Backflow Prevention
City search demand maps directly to Gilbert's governing backflow prevention department.
- Commercial water users and any internal water supply lines that the Gilbert Backflow Prevention Department identifies as posing a contamination threat.
- Gilbert frames backflow as an enforced cross-connection control program for commercial water users, so the risk is staying outside the town's required containment and internal protection workflow.
