Much effort has been directed towards supplying sanitation facilities in urban areas. On an average day during the [International Drinking Water Supply and Sanitation Decade] (1981-1990), 330,000 people in developing countries gained access to safe water and 210,000 achieved better sanitation facilities -- more than double the rate of provision in the 1970s. These are impressive figures, except for the increase in urban population of developing countries which was about 200,000 per day. At the end of the Decade, about one in five urban residents in developing countries were still without adequate water supplies and about one third of all city residents still lacked adequate sanitation facilities.
