    According to World Health Organization, there was increase in the number of people that have access to safe drinking water between 2006 and 2010. Such trends can be countered partly by the use of ceramic water filters that can remove microbial pathogens from water. However, the initial flow rates in such filters are often limited to ranges between 1 and 3 L/hr. The flow rates may vary statistically and decrease with increasing filter use. In this paper, the flow through ceramic water filters is characterized using Darcy’s equation. An effective permeability is obtained for filters with a range of micro-and nanoscale pore sizes. The statistical variations in the flow rates and effective permeabilities are elucidated along with the potency of multiple filter system for scale-up studies in serving a community.
