Standard for Professional Qualification

The Water Quality Association has been invited by ASSE International (American Society of Sanitary Engineering) to help develop a new American National Standard, the “ASSE 22000 Professional Qualifications Standard for Water Treatment Equipment Personnel.”

ASSE International is a membership organization representing the plumbing and mechanical industries. It is accredited by the American National Standards Institute (ANSI) as a Standards Developing Organization.

WQA staff and members, in cooperation with CWQA (Canada) staff and members, are active on the ASSE 22000 Working Group, providing technical input with the goal of a complete and accurate standard aligned with the needs of the Water Treatment Industry and WQA’s members. The Working Group also consists of staff from ASSE, members of the International Association of Plumbing & Mechanical Officials (IAPMO), and the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada (UA).

Like the development and use of the many NSF/ANSI product standards that have resulted in widespread industry product certification for point-of-use and point-of-entry technologies, the ASSE standard will set a national standard for the credentialing of water treatment professionals. While there are a limited number of States that have adopted requirements for product certification, it remains largely a non-regulated, voluntary, market driven certification. The same could be true of a standard for professionals. However, it could also result in new or expanded regulations with required compliance if adopted by jurisdictions seeking the licensing of water treatment professionals.  In addition, the standard could be adopted as an alternative to a plumbing license.

You can find additional information on WQA’s support to our members about professional credentialing and our position on market-driven initiatives here. An FAQ can be found here.

Once the Standard is adopted and issued as an ASSE/ANSI Standard, WQA is planning to offer services to the Standard. It is expected to be aligned with WQA’s existing, comprehensive, voluntary Professional Training and Certification Programs.

WQA will continue to provide updates to members about this ongoing process.
