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

Downloads: 393


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.

Water Safety Planning for Small Communities Step-by-step risk management guidance for drinking-water supplies in small communities

Downloads: 297


Author: WHO
Year of Publishing: 2012
Publisher: World Health Organisation
Institution:

The WSP approach is designed to help a community manage health risks that could threaten its water supply. By following the WSP approach, community members identify and prioritize health risks and, where necessary, take steps, over time,to improve the safety of the water supply using available resources. WSPs are applicable for a range of scales and levels, and in different contexts. A WSP can be developed for all existing schemes, from point sources to piped systems, as well as for new supplies. In new schemes, it should be straightforward for the supporting agency to incorporate the WSP approach into initial community mobilization and project implementation.

Manual Drilling Techniques

Institution: Practica Foundation, EnterpriseWorks/VITA

When a borehole is drilled, different types of sediment and rock layers can be encountered. To drill through all these different layers a range of manual drilling techniques have been developed and are used around the globe. In each case the drilling technique must (a) break or cut the layers, (b) remove the cut material from the hole, and (c) if necessary provide support to the walls of the hole, to prevent collapse during drilling.

Achieving the MDGs for water supply in Sub-Saharan Africa is a daunting task because the magnitude of the problem is ever increasing. There are 284 million people living in rural areas without access to potable water. In order to reach these people, radical solutions, and low-cost soutions are needed - such as manual drilling.
