Shallow drum-lined wells for guinea worm eradication

Treating ponds that are infested with guinea worm cyclops can be difficult in rural areas. The provision of sanitary wells costs money, and the major expenditure is the digging and lining. As a result people often try to economize on the lining, which often results in a poor quality structure that collapses. This article describes a project which provided shallow wells lined with used oil drums. The drums are easily available, and they protect the wells so that cyclops-free water can be obtained in the communities at almost the same site as the infested ponds. -from Authors
