Biosand water filters are an extremely simple and elegant solution to an extremely serious problem: access to clean drinking water. We chose to use biosand water filters in the Maijuna communities after many hours of research into a wide variety of options. The issue that the Maijuna face surrounding drinking water is not the abundance of water, but rather its quality. Each of the four Maijuna villages is located on a river; the quantity of water is astounding, but the quality is less than acceptable for human consumption. Given this, and other social and environmental factors, biosand water filters proved to be the best fit. All of the following criteria were met: they are culturally acceptable, economically affordable, and easy to build, use, and maintain. Most importantly, they work incredibly effectively and therefore promote the health and well-being of the community.
