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 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! | »
Handpump standardisation is the formal or informal mechanism that governs the varieties of community handpumps used within a particular country. In a handful of countries this also includes stand-ard handpump designs. With over a million handpumps in sub-Saharan Africa and new installations every day, handpump standardisation is still vital for the policy and practices of governments and implementing organisations. While rural water practitioners are polarised about the future of formal standardisation, the extent of informal standardisation is of significant importance to the sustain-ability of handpumps across the continent. Of the thirty-five countries in sub-Saharan using handpumps, formal standardisation has emerged in fifteen through regulations (nine countries), and endorsements (six countries). However in the remaining countries, informal standardisation determines what handpumps are installed where, either through recommendations (fourteen countries), or de facto standardisation (six countries). | »
In 2012, RWSN established Dgroups.org as its online electronic platform for membership and discussion. The groundwater and handpump groups have been among the most active communities. The number and depth of contributions has been rich, and several members have asked for a synthesis of the discussions. They main topics that emerged were:
1. Water Quality - particularly iron and pump corrosion
2. Procurement, Quality Control and Installation
3. Sustaining handpumps - what is the average lifespan of a handpump?
4. Handpump component failures and the need to redesign public domain designs
5. The politics of new pump designs: the Squirrel Cage Pump
