Sphere Handbook. 4th Edition. WASH Chapter. Appendix 1: WASH Initial Needs Assessment Checklist (pages: 139-142)

The aim of the Handbook is to improve the quality of humanitarian response in situations of disaster and conflict, and to enhance the accountability of humanitarian action to crisis-affected people. The Humanitarian Charter and Minimum Standards in Humanitarian Response are the product of the collective experience of many people and agencies. They should therefore not be seen as representing the views of any one agency.
