As a member-based association, Committees are the engines which make IAPMO a great organization and are the means by which the organization creates consensus-based codes, support products and programs to facilitate safe and sanitary plumbing systems throughout the world.

These committees are composed of dedicated volunteers who bring their extensive skills and knowledge to the work of the association so others can benefit. Typically, these volunteers are members of IAPMO who share in the mission and goals of the Uniform Codes.
