Backflow Prevention remains a critical link in protecting public health by maintaining the quality of our drinking water systems. Cross-connections are an actual or a potential cross-connection between the public water supply and any source or system not intended for potable use. Backflow Prevention Assemblies are a critical part of protecting our water systems from non-potable and possibly life threatening substances from entering the public water supply. Many cases have been documented where cross-connections have been responsible for the pollution or contamination of the public water supply, and facility distribution systems, which have resulted in the spread of illness. Ensuring that we have well trained, educated and experienced people working and testing these life safety devises should continue. Please do not allow these licenses to be discontinued.
