A CSA Technical Committee for drinking water treatment units has been established, according to the Canadian Water Quality Association (CWQA). CWQA helped create the newly named CSA B483 Technical Committee, which has a mandate to develop a Canadian standard for drinking water treatment units.

At a meeting held in May 2003, the new committee, made up of water treatment industry representatives, government regulators, product users and other interested parties, agreed that there is a need to have a Canadian consensus document that addresses the complete drinking water treatment unit product, references NSF standards as applicable and addresses other general plumbing product certification requirements (mechanical compatibility and performance issues).

Technical Committee Chair Scott Macdonald (Envirogard Products Ltd.) is currently working with CSA to build a "balanced matrix"
