Human Water Cycle: Water and Wastewater Treatment and Reuse

Topic Sustainability

CPD Hours 3*

Price IChemE Member: FREE, Non-member: £265 + VAT


Chemical engineers have a role to play in optimising water and wastewater treatment and in minimising their impact on the environment. This course covers the why, what and how of not only treatment, but water as a whole, through the human water cycle.

As the Sustainability Hub assists chemical engineers in supporting the UN Sustainability Development Goals, this training course will be a key knowledge strand for setting a solid foundation towards making steps for achieving SDG 6: Clean Water and Sanitation aims and targets.

The course includes pre-recorded and interactive content, recommended further learning and an end-of-course assessment. You will receive an automated end-of-course certificate, subject to successful completion of the assessment.

As part of the Sustainability Hub’s suite of on-demand training courses, IChemE Members can currently obtain free access to this course by inputting a discount code. See below for more details.

Learning outcomes

By the end of the course, you will gain an introductory level understanding of:

  • the water cycle and its circular nature
  • water contaminants and water quality management
  • the effect of wastewater on the environment and why we treat wastewater
  • an understanding of treatment technologies and their capability to treat various waters and wastewaters to the required standards
