With increasing numbers of reported cases of Legionnaires' disease, ANSI/ASHRAE Standard 188-2018 "Legionellosis: Risk Management for Building Water Systems" requires the implementation of a water management program which includes the design and operation of building water systems. Part of this design requirement is to properly decontaminate a potable water system before occupancy. After the building is in operation, control measures, such as supplemental disinfection, may be needed to reduce the risk of Legionella amplification. This session reviews methods for decontamination of water systems before building start up, and the application of supplemental disinfection as an ongoing control strategy.
