Book Description
This manual describes the causes and prevention of backflow and cross-connections in potable water systems. Here is complete guidance for establishing a cross-connection/backflow prevention program for a water utility. You'll learn the water purveyor's legal responsibilities, as well as the customer's responsibilities in backflow prevention. The manual covers risk assessment, types of programs to consider, and program administration. Until the cross connection control program is fully developed, the water purveyor is at maximum risk of potential liability. M14 also explains the hydraulics of backflow, the two types of backflow - backsiphonage and backpressure, and the conditions that can cause backflow and a potential cross-connection (such as a water main break).
