Every two years, WorldSkills brings together young professionals from around the world for the international World Championship of Vocational Skills. In the discipline “Water Technology,” which is being held for the fourth time as an official skill in the Manufacturing and Engineering Technology category, emerging professionals from the water supply and wastewater sectors compete against each other. Water technicians play a key role in the operation, maintenance, and control of complex systems and therefore require in-depth knowledge of engineering, natural sciences, and environmental management.
