The course utilizes problem-based learning and a selection of real life cases that give insight and overview over sustainable water and sanitation situations and possible solutions. Students will be introduced to cases, and confronted with the complexity of water and sanitary challenges. How should we approach and evaluate the situation? What physical, technical, economic and social factors are important for our choice of technology? Who are the stakeholders and how should they be involved? How do we secure a sustainable management of the situation? Students will work with specific aspects of case situations. The cases will introduce students to different technical solutions to address water and sanitation challenges in different locations world-wide. For each case, a series of questions will be asked, which will require students to seek out, evaluate and apply appropriate knowledge to the given situation and justify chosen solutions. The cases and support material are available on Canvas and an internet database. Important issues are supported by lectures and each case is followed up by an in-class discussion.
