With a growing world population and climate change, the pressure on water supplies is set to increase. If you want to play a role in addressing the environmental challenges facing the world today, then the Diploma in Environmental & Water Technology (EWT) is the course for you.

Jointly developed with the PUB, this diploma will equip you with a firm grounding in the key areas of water technology, waste management and resource conservation, as well as pollution monitoring and control.

In your first year, you will be introduced to basic concepts of environmental science, engineering and technology with modules such as Noise Monitoring & Control, Computer Aided Design and Hydraulics. In your second and third year, you will move on to in-depth modules in various aspects of environmental engineering and water technology, such as air and water quality monitoring & control.

In your final year, you will work on an environmental innovation & research project and go on a four-month internship. You can opt for hands-on learning opportunities at our Centre of Innovation in Environmental and Water Technology (COI-EWT) and work alongside research engineers and scientists on industry-based projects.

All EWT students will also have the chance to learn about sustainable environmental practices by participating in an enhanced study trip to destinations such as South Korea, Taiwan or Masdar City in Abu Dhabi.

With additional Workforce Skills Qualification (WSQ) Certificates in Noise Monitoring and Industrial Noise Control, you can look forward to better job prospects in the industry!


You will be well prepared for careers in government agencies, multinational corporations, university laboratories and research institutes. You can work as an environmental technologist, assistant engineer, research officer, water treatment specialist and many more. Additional WSQ certificates will also qualify you for jobs such as a Noise Monitoring Officer or Noise Control Officer.
