Community Water Supply Management

Safety, Health and Environment (SHE)

Course Summary:

Although much progress has been made over the last three decades, still more than one billion people lack access to a safe, reliable and affordable water supply, and more than twice that number still lack access to basic sanitation. This course provides the essential skills and knowledge required to plan and implement, with communities, water supply and sanitation projects and programmes worldwide, particularly in less developed countries.

Course Objectives:

  • design and implement appropriate and sustainable solutions to water supply and sanitation for small, rural communities in particular in developing countries, with due regard to the technical, social and institutional constraints imposed by the surrounding environment
  • assess water supply and sanitation needs for communities in villages and refugee camps
  • plan and implement water source evaluation and development programmes, including low-cost well drilling
  • facilitate community participation and management projects and programmes
  • design, cost and implement small sustainable water distribution, storage and treatment systems
  • evaluate the health impacts of community water supply and sanitation systems.
