Supplying safe water to rural areas of developing countries demands an awareness of more than treatment methods. Although water sources, treatment methods, and a discussion of transport and distribution make up most of this report, it emphasizes other concerns to ensure the safety of drinking water. The success or failure of the adequate operation of a water source depends heavily on the source's operator; his capabilities are often critical, and he should receive intensive training. A public water supply scheme should also be preceded by public education in water safety. The first part of this report is divided into five sections: an introduction, containing general comments on the subject area, water consumption, water sources, water treatment, and water transport and distribution. Part two contains a literature survey.
