The potential of tube-wells to provide clean water for drinking and sufficient quantities for irrigation is very high. Manual well drilling techniques are a good alternative for heavy and expensive conventional drilling methods:
- Remote areas can be accessed to serve communities that are not reached by national water supply programmes;
- The equipment can be produced locally which allows small enterprises to start up a business;
- Manual drilling is 2 to 5 times cheaper than conventional drilling for wells of equal high quality.
PRACTICA works on professionalising the manual drilling sector throughout Africa by large capacity building programmes. Instruction and training manuals on the fabrication and operation of the technologies are available in our library. We also continue our work to adapt the technologies for particular sectors and contexts. A range of manual drilling techniques can be used according to the local hydrogeology and capacity.
