Low technology drilling methododogy (LTDM)

Simple drilling methods for rural handpump-equipped water supplies are becoming more widespread in their use. However, work to-date in this area has tended to concentrate on technological aspects. The sociological dimension cannot be ignored otherwise the application of sound engineering principles could fail. This paper presents a Low Technology Drilling Methodology (LTDM) which attempts to integrate social, economic and engineering criteria, and (if adhered to) should ensure success and sustainability of borehole-based rural groundwater supplies.
