L’impact des forage manuels sur la réalisation de points d’eau durables au Tchad

Cette étude examine l’impact des intervention de forages manuels sur l’amélioration du taux d’accès a l’eau potable au Tchad. | »


The present study aims to give a general idea and it is extend to the whole country; the results of this study must be used to target specific ares where more detailed analysis are required in order to have a detailed idea of the best strategy and location to support manual drilling.

It takes into consideration the methods and results achieved in a previous study carried out during 2006 (GIS ANALISYS OF EXISTING HYDROGEOLOGICAL INFORMATION AND MAP PRODUCTION AS A SUPPORT FOR THE IDENTIFICATION OF SUITABLE AREA FOR MANUAL DRILLING TECHNIQUES IN UNICEF WATER PROGRAMME IN TCHAD) that focused its attention to 5 regions (Mayo Kebbi, Tandjile, Kanem, Ouaddai, Guera, Batha, Hadjer-Lamis), extending the analysis to the whole country and modifying some of the assumptions on the basis of the direct experience of manual drilling impelement by UNICEF after 2006 in Chad | »

Chad’s Growing Manual Drilling Industry

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. | »

Manual Drilling Compendium 2015 RWSN Publication 2015-2

Manual drilling refers to several drilling methods that rely on human energy to construct a borehole and complete a water supply. The various techniques can be used in areas where formations are quite soft and groundwater is relatively shallow.

Manual drilling can provide safe drinking water. The equipment can easily be transported to remote, or difficult to serve populations which would otherwise be left behind. The lower costs compared to machine drilling are appreciated by households, businesses and governments. Manual drilling also provides local employment.

Manual drilling methods are being used to provide water for drinking and other domestic needs at least 36 countries around the world. In some places, manual drilling methods are well established.

The compendium provides a useful overview for those wishing to further examine the impacts and challenges of manual drilling, and, more importantly, improve practices on the ground. It is hoped that the document will spur others to undertake fur-ther studies as well as research to document stories and analyse the promotion, uptake and use of manually drilled boreholes. In addition, the compendium should also enable those promoting manual drilling to realise that they are certainly not alone in their endeavours! | »
