Cheap, Clean, Safe Drinking Water,

is what many of us take for granted,

but in many countries that is not an option without boiling or some other form of sterilisation,

but here is a great idea from Hydrologic Social Enterprise, hydrologic silver-impregnated ceramic water purifier or CWPs are engineered in Cambodia using local resources and skills, the ceramic inner pots fit securely into the top of a specially designed plastic container with a lid to protect against re-contamination, the outer container has enough space to store about 12 liters of filtered water, when the inner pot is filled with untreated water, that water then percolates through the ceramic by a system of gravity filtration at a typical rate of 1-3 liters per hour, bacteria are physically blocked and killed by the silver contained in the CWP. hydrologic silver-impregnated ceramic water purifiers are proven to remove at least 99.99% of harmful bacteria from drinking water, the units are proving to be a great success with their use in countries such as Peru, Ecuador, Colombia, Kenya, Tanzania, Rwanda, Uganda, Myanmar, Cambodia, Vietnam, Laos, China, Philippines and Indonesia, what a neat and eloquent answer to a worldwide problem.
