Cross-connection control and backflow prevention
Conference
·
OSTI ID:6820718
We discuss the elimination of potable-water contamination through backflow prevention, and present the elements of a comprehensive cross-connection control program currently in use at Lawrence Livermore National Laboratory (LLNL). This discussion includes the structure, objectives, practices, and policies which drive the LLNL program, along with typical examples of cross-connections. In our program, we emphasize that two types of cross-connections, inlet and pressure, should be eliminated to prevent backflow of contaminated water into potable systems. We also present material gathered from available literature on the theory of backsiphonage and backpressure that will provide concepts to form an effective cross-connection control program.
