The Role Materials Can Play in Legionella Risk Mitigation

Risk minimization strategies for biofilm and bacteria prevention need to include consideration of piping system materials.  Research and real-world experience shows that piping material affects biofilm growth rates and chlorine consumption in water, while common disinfectants used to prevent bacterial growth have significant impacts on piping system integrity.  Best-in-class materials should possess resistance to bacteria and biofilm growth, and to all forms of chlorine disinfection.  Attendees will see evidence of why chlorinated polyvinyl chloride (CPVC) possesses both of these forms of resistance, and should be strongly considered by designers as part of their risk minimization strategy.
