Standard 514 provides minimum practices to manage overall risk from microbial hazards as well as risk from physical and chemical hazards associated with potable and non-potable building water systems. Consistent with the provisions of Standard 188, Standard 514 provides a framework for the systematic development of water management programs, from design and construction to occupancy, including post-occupancy modifications and renovations.

This presentation will provide a detailed description of the differences and similarities between ASHRAE 514 and 188. This understanding will allow the proper application of the strategies within the standards and help those managing water systems to better protect those they serve. It is well known that individuals can be exposed to waterborne pathogens, chemicals and physical hazards through contact, ingestion or inhalation of aerosols. A robust water management program as detailed in ASHRAE 514 can help building owners, public health officials and water purveyors reduce the risk of physical, chemical, and microbial hazards through water systems.
