Hazard Analysis and Critical Control Point (HACCP) methodology is a structured, systematic, cost-effective process best known for its successful, widespread use in food safety. The adaptation of HACCP to building water systems has proven effective for ensuring the safety of building water systems by preventing illness and injury.

In building water systems, microorganisms can enter the plumbing systems and amplify to large numbers over time. If they are released into the environment and inhaled by potentially susceptible individuals, they can cause serious illness. Such pathogenic microorganisms include Acanthamoeba, Acinetobacter, Klebsiella, nontuberculous mycobacteria (NTM), Pseudomonas and possibly the best known, Legionella. Legionella pneumophila is responsible for Legionnaires’ disease, which results in approximately 4,000 deaths every year.

By following the seven principles of HACCP, HACCP methodology for building water systems identifies specific, potentially hazardous agents and specifies measures for their control to ensure the safety of the water in buildings. The use of HACCP has proven effective and practical for controlling the growth and dispersal of pathogens in building water systems. To learn more, contact us at waterhaccp@nsf.org.


The application of HACCP to building water safety is invaluable for protecting the overall health, safety and well-being of the public. Such programs have proven effective and practical for controlling the growth and dispersal of clinically significant pathogens in building water systems. Through NSF training, you can learn how HACCP is applied to the hazards associated building water systems.


NSF’s HACCP courses are presented by knowledgeable water safety experts who possess scientific and academic backgrounds along with the hands-on industry experience necessary to communicate the relevant course information and the latest issues related to building water systems safety. Each NSF instructor has experience working with public drinking water supplies and microbial risk management in building water systems.

Benefits of Training

It is nearly impossible to eliminate the intrusion of pathogens into building water systems. However, through NSF‘s HACCP for building water systems training, facility managers can learn tactics and strategies to help control the conditions that can lead to their amplification. NSF training provides a practical, resource-efficient method to prevent the diseases associated with building plumbing systems at a reasonable cost. You’ll learn how these methods apply to a wide variety of building water systems with varying size, purpose and design.

Why Work With NSF?

Serving the water industry since 1944, NSF provides an extensive array of services to help ensure the quality and safety of products and their impact on public health. NSF is well respected by manufacturers, public health officials and drinking water utilities. Our experience working with manufacturers and national, state and provincial regulatory agencies provides us with the knowledge and expertise to provide valuable, in-depth training courses on a variety of topics.
