Course Objectives 

The course is designed to provide professionals with a thorough understanding of the increasing complexities of the WASH sector. It provides students with the latest contextual and technical skills to plan, design and implement sustainable activities and programmes within the framework of the fundamental principles of the WASH sector, namely public health and equitable access to water supply and sanitation services. Designed to contribute to Agenda 2030 (SDG 6) by focusing on all aspects of sustainable WASH interventions, this course is strongly practice-oriented, allowing a direct link between theory and reality/complexity on the ground. After completing this course, participants will be able to:

  • Identify and analyse context-specific challenges and plan tailor-made WASH interventions to improve sustainable access to WASH services and facilities in complex institutional environments, both in the field of cooperation and humanitarian aid
  • Conduct a context-specific public health risk analysis of inadequate WASH services and design appropriate prevention strategies
  • Conduct a systematic analysis of environmental, social and technical problems, both in urban and rural contexts, and design appropriate intervention strategies.
  • Confidently implement the wide range of advanced WASH intervention tools: from specific technical approaches in water supply and sanitation to current approaches developed in the field of hygiene promotion, as well as sectoral assessment tools.
