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

Downloads: 390


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.

Strengthening the Domestic Drilling Industry Lessons from the Mozambique

Institution: WSP

Improving water supply in rural areas of Mozambique continues to be a major challenge. The highly dispersed rural population and difficult hydrogeology make even the most basic level of service--a borehole with a hand pump—accessible to only about half of the rural population. Even when basic access is available, 17.1 percent
of hand pumps are out of service at any one time, rising to nearly 30 percent in the Northern provinces.

With the support of the World Bank’s Water and Sanitation Program (WSP), water drillers in Mozambique began tackling this challenge through the creation of the Mozambique Drilling Association (APM). As the first of its kind, the association introduced several key initiatives to boost the capacity of drillers and to strengthen their voice to the government. The purpose of this learning note is to share lessons learned from WSP’s support to APM and to highlight additional areas of growth and development for the association.

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.

For the construction of safe groundwater points different well construction methods exist. Wells can be drilled with machines, drilled manually or dug by hand. Before selecting the most appropriate method, several criteria, such as geology, depth of aquifer, yield and location should be reviewed.

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.

This Borehole Costing Model is a spreadsheet in Microsoft Excel 2003

Once set up the model can quickly calculate the actual cost of a borehole (not the price). The first time the model is used it requires the unit costs to be entered for different materials and rigs. The model was built by Tom Heath, Richard Carter and Kerstin Danert. The model consists of three components: Model Unit Costs, Borehole Specifications and Results.

Institution:

Hand drilling methods can offer low cost, rapid access to shallow, unconsolidated aquifers typically found in dambo environments (seasonally waterlogged African wetlands).
This thesis presents the findings from an evaluation of three hand drilling techniques (augering, percussion drilling, and borehole jetting) regarding to their suitability for groundwater supply in upland and lowland dambos in Malawi.

Code of Practice for Water Well Construction NIGERIAN INDUSTRIAL STANDARD

Author: STANDARDS ORGANISATION OF NIGERIA
Year of Publishing: 2010
Publisher: STANDARDS ORGANISATION OF NIGERIA
Institution: STANDARDS ORGANISATION OF NIGERIA

This Nigerian Code of Practice for Well Construction was elaborated by the Technical Committee for Water Well Construction.
Groundwater development is one of the sources of the Federal and State Governments Water Supply Intervention Programmes under which government embarked on construction of open wells and boreholes in order to increase access to portable water to Nigerians. However, water well construction is still characterized by cases of “failed hole”, poor quality service, and unprofessional conduct of drillers and lack of established code to regulate the practice of water well drilling in Nigeria. These are serious concern to government, donor agencies and sector stakeholders who see them as militating factors towards attainment of water supply project objectives in particular and Millennium Development Goals (MDGs) in general. This Code of Practice was therefore elaborated to provide the framework for water well construction in Nigeria.
In the elaboration of this Code of Practice, reference made to Nigerian Industrial standards and National standards of other countries are acknowledged.
