The WSAA National Product Appraisals program is a voluntary scheme introduced by the Water Services Association of Australia to provide a single coordinated appraisal of a product's conformity to the needs of the urban water businesses. It was developed with industry assistance, and draws on the collective knowledge and experience of the urban water businesses and industry specialists.
