The use of appropriate equipment paired together with adequate training helps communities in the developing world to meet their own demand for water at a cost they can afford to pay. Extremely light and portable equipment can be used to drill. Sound application of drilling equipment requires common sense to achieve good results. To open a hole, all the operations must adhere to some basic operational rules defined by existing field experience, together with accepted engineering theories, if the drilling and well construc-tion are to succeed. This manual explains in practical terms the basic drilling techniques. It describes the use of fluid circulation in soft ground formations, and com-pressed air and hammers for hard rock. It discusses well design, types of pump and their installation, screen selection, and testing.
