Criteria for successful sanitation programmes in low income countries.

In the International Drinking Water Supply and Sanitation Decade (1981-90), the development of a consensus on the concept of sanitation and the planning and implementation of effective and efficient sanitation programmes was not emphasized. Yet lack of good sanitation is a growing burden and environmental threat. Significant improvement of human health cannot be achieved without good environmental sanitation conditions and practices. A consensus on what makes a sanitation programme successful can help to conserve limited funds and spend those available more wisely. It will also help to reduce the increasing flows of waste poisoning precious sources of drinking water. This article was written to stimulate discussion on what attributes can be taken as characteristic of good environmental sanitation programmes, and on which indicators can be used to assess those attributes in actual sanitation programmes.
