This field note is written for water well drilling enterprises as well as other agencies which manage, or are involved in drilling projects. 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. Once you are familiar with this field note, you will be in a much stronger position to calculate drilling costs, consider prices and deal with business realities.

Developing Groundwater: A guide for rural water supply

In many rural areas, groundwater is the only feasible way of providing safe, reliable water supplies. However, developing groundwater is not always straightforward. To meet the targets set out in the Millennium Development Goals, more attention needs to be paid to finding and developing groundwater in a sustainable, cost-effective and participatory manner. Developing Groundwater provides a user-friendly guide to this key topic, bringing together for the first time the wide range of techniques required to develop groundwater for community water supplies. This practical manual gives information on effective techniques for siting wells and boreholes, assessing the sustainability of sources, constructing and testing the yield of boreholes and wells, and monitoring groundwater quality. The authors set the technical aspects of rural water supply firmly in their socio-economic context, so that readers can take proper account of community concerns as well as purely engineering questions. Packed with helpful illustrations this book is indispensable for all rural water supply project staff in developing countries.

Alan MacDonald is a hydrogeologist at the British Geological Survey. He has worked extensively in Africa, Asia and the Pacific in partnership with government departments, NGOs, research institutes and rural communities. Much of his work has focused on the practical issues of developing groundwater resources for rural water supply.

Draft Review of the Household Arsenic Removal Technology Options

Institution: Handpump Technology Network

Arsenic is widely distributed element in the earth’s crust and ranks twentieth in elemental presence. As a Group V element, arsenic exhibits a broad range of chemical reactivity and it is commercially used in alloys with lead. Arsenic in natural water has been reported from several countries including Bangladesh, China, Chile, Ghana, India, Nepal, Rumania, Taiwan, USA and Vietnam. In India, arsenic pollution is mostly of geological origin. However, ground water pollution of anthropogenic origin - due to industrial or mining waste - has been reported from Chennai in Tamil Nadu and Rajnandgaon in Madhya Pradesh.

Drilling Boreholes for Handpumps Working Paper 2 on Water Supply and Environmental Sanitation

Author: WURZEL, P.
Year of Publishing: 2001
Publisher: Skat
Institution: RWSN

This booklet seeks to suggest ways in which funds can be better used for making safe water available to the poor by illustrating how drilling costs can be reduced without compromising water quality, water quantity, or the productive life of the borehole. These arguments are directed towards the rural water supply sector as a whole. Those directly addressed are primarily decision makers, government civil servants, planners and implementers of water projects who are not experts in drilling, as well as technical people, project leaders, technical aid personnel etc. This publication is neither a detailed drilling manual nor a methodology of drilling methods.

The author draws on his extensive experience as a member of the UNICEF Water and Environmental Sanitation community. He hopes that his views and proposals will be a catalyst for change, and that this contribution will stimulate interest in experimenting with ideas on low cost drilling of boreholes for handpumps.

Technological advances over the past decade have made solar water pumping a viable option for potable water service delivery in rural settings. Solar pumping is an especially attractive alternative when poor groundwater quality or high population density and growth limit the applicability of boreholes fitted with handpumps. However, globally-accessible resources that specifically speak to the various technological, financial, social, environmental, institutional, and operational elements of sustainable solar pumping designs are limited. This workshop provides participants with an opportunity to explore various aspects of holistic design of solar pumping systems through guided group discussion.

The drilling method developed by the Escuela Móvil de Agua y Saneamiento (Mobile School for Water and Sanitation) in Bolivia is a hybrid between washboring, percussion and rotary drilling. It permits to drill through all kinds of loose soils, as ell as consolidated materials and light rock. It will not, however, penetrate hard original rock or boulders (e.g. ancient river beds underground)

In Panama, the indigenous Ngöbe people in the ÑöKribo coastal area are a group disproportionately affected by a lack of improved access to drinking water and challenges to the feasibility of piped gravity fed water systems that typically serve the rest of the country. An NGO aiming to ameliorate this situation introduced two improved groundwater supply technologies to the region: bailers and EMAS hand pumps. This study assesses the comparative performance of these systems while evaluating the respective performances of existing water sources, using the wide variety of quantitative and qualitative data obtained.
