Increasing access to groundwater is a high priority in Sub-Saharan Africa. One key to this is to reduce the costs of conventional drilling and borehole construction. This field note, describing a recent study in Ethiopia, sets out how this may be done.

The Rural Water Supply Network is a global knowledge network for rural water supply technologies and approaches. The website provides many excellent publications on various topics on rural development, particularly on hand drilled wells. This section presents an overview of the scale and type of hand drilling activity being undertaken in selected countries and the organisations involved.
This document provides a short summary of each of the hand drilling techniques being utilised today; a country-by-country overview of the extent of hand drilling taking place in select countries; an annotated list of organisations involved in promoting and supporting hand drilling and an extensive list of literature, from published articles to training materials and online videos.

Using a step-by-step approach it gives clear guidance on how to cost and price the construction of drilled water wells. It also provides tips on business management with an emphasis of the realities faced in many countries in Sub-Saharan Africa.

The most common way of disinfecting is with chlorine. This technical note explains why disinfection is important, why chlorine is used, how it works, how to test for its presence and where and when to test.
