Emergency water sources : guidelines for selection and treatment : trainer support notes

This material is intended to complement the publication Emergency water sources : guidelines for selection and treatment. It is intended to familiarize field workers with using the manual to select the most appropriate water sources and treatment processes in emergency situations. This training material is divided into three units. Unit 1 introduces the principles of assessment of emergency water supplies and presents an overview of how the guidelines may be used. Unit 2 introduces the section of the manual dealing with selecting a survival level of water supply which may be provided in the initial phases of an emergency. Unit 3 focuses on the selection of a longer term water supply and treatment process which would be provided during a slow onset emergency or after a survival level of water supply had been established. The format of each unit consists of a presentation by the trainer, followed by an exercise undertaken by trainees in small groups. The sessions would be concluded by a plenary discussion of the answers to the exercise and a final summing up of the key points to the unit by the trainer. A case study of Hartisheik, Ethiopia contained in Unit 4 which gives sample solutions for survival supply and for longer term supply, along with several survey sheets, is included for use with the exercises in Unit 2 and 3. A case study of Kibogoye, Eastern Zaire presenting water treatment selection background and an example solution supplies additional information for Unit 3. Each unit including the case study contains notes for trainers, master copies of overhead projector slides, and handouts for course participants.
