Certified Water Technologist (CWT) by the Association of Water Technologies

The Association of Water Technologies offers a Certified Water Technologist (CWT) program. The CWT certification represents the highest professional credential in the industrial and commercial water treatment field. It provides professional recognition for individuals involved in water treatment and technology to indicate to the general public, co-workers, employers and others that an individual has achieved a high level of experience, knowledge and education in the industry. The CWT designation assures that water professionals possess a core body of knowledge and have extensive professional experience in all aspects of water treatment.
