Critical evaluation of the appropriateness of ceramic and biosand filters in rural Cambodia

Thesis, University of Guelph, 2010Household or point of use (POU) water treatment technologies have been identified as successful interventions for providing safe water to rural households. In terms of water treatment technology, no one method can treat every type of source water and the process of matching a technology to a particular water source is missing from current POU implementations. Currently, there are two water treatment technologies widely implemented across Cambodia: ceramic water filters and BioSand filters. Both have proven to reduce diarrheal disease by up to 50%; this study contributes to debate on the sustainability of these systems in terms of effectiveness and long term health impact
