Organisation in an Emergency Water demandWater supplyWater distribution Quantity Which surface or groundwater sources in the area are affected? What is their capacity? How can this water be brought to the people in need? Quality What are the problems related to water quality now and how will the situation develop? How is the water quality of these sources? What are the possibilities for treatment if required? Any existing leakages affecting water quality? Adapted from: DAVIS & LAMBERT (2002)

Approaches to Water Purification in Emergencies Point-of-use Water Supply and Purification Camp Water / semi- centralised Supply and Purification PrinciplesEnd-users (households and communities) are trained to apply simple multi-barrier methods based on the HWTS approach. After and during an emergency, a mobile water treatment unit is brought close to the water source and installed and operated by trained staff. TechnologiesSedimentation, Coagulation, Disinfection, Boiling, SODIS Treatment units AdvantagesLow-costReady-to-use, very effective DisadvantagesHigh responsibility of end userExpensive, knowhow for O&M AB

On the right: Self-disinfecting Katadyn Filter elements also have a high performance. They work with a micro porous ceramic filter with silver incorporated in the ceramic structure. B 19 5.

Approaches to Water Purification in Emergencies The concrete measures to be taken after a disaster depend on the answers to the assessment questions, the geographical and climatic context, the reason for people being without water and the type of target groups.

E.g. modular kits pumps, treatment units, water tanks and distribution systems. 22 6. International Emergency Responses in WASH HOUSE & REED (1997) Provision of modular mobile treatment units to treat either surface or groundwater from a nearby source in the short run. Usage of locally available materials, methods and skills to benefit the local population and to improve effective operation and maintenance of the system in the long run.
