Water Demands in Low-Income Countries
The challenge is enormous: one billion people still lack access to safe water, two billion lack safe sanitation. Slow progress is not acceptable, as more than three million children still die every year from avoidable water-related disease. (World Bank Water Supply and Sanitation web-site, March 1, 2000, http://www.worldbank.org/html/fpd/water/).
Dirty water has become the world’s most dangerous killer. At least twenty-five thousand people die every day from the use of it…Diarrhea alone kills at least 4.6 million young children every year. About 200 million people are victims of schistosomiasis caused by contaminated water on the skin. Five hundred million have trachoma, one of the main causes of blindness because of dirty dishwater. About half of the people living in developing countries do not have safe drinking water (La Jornada, 1992, p. 17).
It is estimated that at least 25% of rural water supplies in developing countries are not working, and in some countries, construction of new facilities is not even keeping pace with the rate of failure (Mu, Whittington and Briscoe, 1990, p. 522).
