Testing Handpumps
Handpumps are still best suited to alleviate the drinking water supply crisis because they are cheap. Moreover, the borehole's or well's surface can easily be sealed (by means of a concrete lid) against foreign substances that might lead to contamination and thus health risks something which cannot be done with "open" waterholes.
