The long-awaited ASHRAE standard on Legionella is now available. ANSI/ASHRAE Standard 188-2015, Legionellosis: Risk Management for Building Water Systems establishes minimum legionellosis risk management requirements for building water systems. The standard requires building owners to establish a water management program to meet the standard's requirements for risk management of potable and non-potable water systems. The standard offers specific and detailed requirements for what the water management program must accomplish and how it must be documented, but does not mandate or restrict the use of specific strategies.
