Outlines a performance-based approach to the maintenance of cooling water systems with respect to the control of microorganisms, including water treatment with monitoring, and assessment and control strategies to help create a low risk environment within the cooling water system.

This Standard outlines a performance-based approach to the maintenance of cooling water systems with respect to the control of microorganisms, including Legionella spp., within such systems. This approach combines automatically regulated water treatment with monitoring, assessment and control strategies to help create a low risk environment within the cooling water system.
