The majority of water sources in developing countries are unimproved. Families and schools typically dig pits which then fill naturally via rain or ground water. Some areas collect water from nearby rivers.
These methods are all subject to ground and exterior contamination. Many of these sources are shared with animals from the local area, and many are also used for bathing.People from many communities walk miles just to fetch water each day. This consumes a major part of peoples’ lives in water poor areas. In fact, women spend over 200 million man-hours EVERY DAY collecting water.
