Under the umbrella of the Rural Water Supply Network (RWSN), SKAT has been commissioned by USAID / UNICEF to study how to optimize the costs of boreholes construction in the three countries of Zambia, Ghana and Burkina Faso. The main output of the studies is the definition of a national protocol/code of conduct for the construction of boreholes specific to each country.

Bush Pump Zimbabwe Standard Specification

Institution: Department of Water Resources and Development

The Bush Pump has been used in Zimbabwe for over 60 years. It was first designed in 1933 by Tommy Murgatroyd, a water suuply office working in Plumtree, Matebeleland, and some of his early pumps survive to this day.

The Zimbabwe 'Bush Pump' is almost unique on the African continent in that it was conceived and designed and is wholly manufactured within Zimbabwe itself. The family of 'Bush Pumps' owe their success to a simplicity of design and rugged construction which originated from Murgatroyd's pioneering work. The Bush Pump continues to serve the people of Zimbabwe, seventy years after the first pumps of the family were designed and built.

Capitalisation D'Experiences sur les Forages Manuels a Madagascar

Des techniques appropriées au contexte malgache et adoptées par les opérateurs :
well jetting, rota sludge et madrill. La recherche action est porteuse d’améliorations constantes et elle apporte une réponse aux contraintes rencontrées par les utilisateurs. Avec plus de 2000 forages réalisés le secteur du forage manuel a acquis sanotoriété en dépit de son absence dans la politique nationale du secteur eau. 4 fois moins cher que le forage motorisé le coût des forages manuels pratiqué à Madagascar est 2 à 3 fois moins élevé que dans les autres pays d’Afrique.
Un potentiel à confirmer pour donner une idée du marché et de l’impact attendu. Les standards d’équipements sont disparates et la définition d’un ensemble de normes techniques détaillées pour les forages manuels est indispensable.

Institution: Skat Foundation

In Chad, manual drilling is a growing industry. This report provides an overview of manual drilling in Chad today. The report is intended to stimulate interest in more research, documentation and action regarding the diffusion of manual drilling within the country and its implications. The technology is increasing in popularity and spreading within Chad, including in the capital N’Djamena. Private enterprises and non-governmental organisations are promoting manual drilling and water users are investing in their own manually drilled wells.

La réalisation d’ouvrages pérennes d’exploitation d’eau souterraine est fondamentale pour l’accès universel à l’eau potable. Ce docu-ment, Le Code de bonnes pratiques pour la réalisation de forages présente un cadre pour l’accès à l’eau sur la base de critères écono-miques et de santé publique. Ces bonnes pratiques visent à optimi-ser le rapport qualité/prix de l’investissement à long terme. Les forages étant construits pour fonctionner sur une durée de vie de 20 à 50 ans, le plus bas prix ne représente pas toujours l’optimum économique, en particulier lorsque la qualité des ouvrages est sacri-fiée afin d’économiser sur les investissements. La réalisation de fo-rages très bon marché ou de mauvaise qualité peut engendrer des dysfonctionnements prématurés ou la contamination de la res-source en eau. Ceux-ci sont par la suite abandonnés par les usagers et n’ont pas à l’évidence un bon rapport coût-efficacité.

Sustainable groundwater development is fundamental in order to provide universal access to safe drinking water. This document, The Code of Practice for Cost Effective Boreholes provides a basis for the realisation of economical and sustainable access to safe water. The term “cost-effective” means optimum value for money invested over the long term. Boreholes are drilled to function for a lifespan of 20 to 50 years. Thus, the lowest cost is not always the most cost-effective, particularly if construction quality is compromised to save money. Cheap drilling or poor construction quality can lead to premature failure of the well or contamination of the water supply. Boreholes that are subsequently abandoned by the users are clearly not cost-effective.

The Code of Practice for Cost-Effective Boreholes has been officially endorsed by the German Federal Institute for Geosciences and Natural Resources (BGR).

It is recognised that drilling interventions vary widely both nationally and internationally and are not always cost-effective. The objective of this consultancy is to identify and set out key procedures for cost-effective boreholes as appropriate for Zambia.

The report considers the existing status of borehole drilling in Zambia. Chapter 2 reflects on the meaning of “cost effective” and key areas of concern are highlighted. Chapter 3 summarises borehole costs and prices in Zambia. Chapter 4 examines Zambian policies and practices with respect to the generic principles of the COP and the proposed structure of the “Guideline to Standard Procedures for Design and Construction of Protected Water Points” (Appendix 5). Headings in the report text include brackets which refer to the related numbered section in the proposed guideline structure. The Report text reflects on current practices, and recommends action for further consideration and inclusion. Recommendations are italicised in the text.

Code of Practice for Water Well Construction NIGERIAN INDUSTRIAL STANDARD

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.

Community Water Supply: the handpump option Rural Water Supply Handpumps Project

This document presents conclusions of five years of work devoted to the assessment of available technology and management options for the wide-scale implementation of community water supply systems. An examination of policy options for developing countries suggests that economic stability and growth can be enhanced if the rural and urban-fringe populations are adequately served with non-polluted water supplies. An adequate water supply is one of the basic needs of life, but is often lacking in developing countries. Not only has the rate of construction of improved water supply systems been slower than the target of complete coverage originally set under the International Drinking Water Supply and Sanitation Decade, but also many of the schemes already completed are not in satisfactory operating condition. A sound investment strategy in this sector calls for low-cost and maintainable solutions to achieve wide-scale coverage of the rural and urban-fringe communities in developing countries.
