Emergency relief technical notes
These illustrated notes have been prepared by Loughborough University's Water, Engineering and Development Centre (WEDC) for the World Health Organization. Their aim is to assist those working immediately or shortly after an emergency to plan appropriate responses to the urgent and medium-term water and sanitation needs of affected populations.
The notes are relevant to a wide range of emergency situations, including both natural and conflict-induced disasters. They are suitable for field technicians, engineers and hygiene promotors, as well as staff from agency headquarters.
