This report maps out the favourable zones for manual drilling and low cost pumps in parts of Madagascar. The report outlines the drilling techniques (which cost between US$80 and US$ 250 per well); the pumps (Canzee and Rope Pumps costing US$ 40 to US$ 175) and provides a series of maps of hand drilling and pump potential in the regions of Amoro I Mania, Haute Masiatra, Antisinanana. Analanjirofo, Alaotramangoro, Vatovavy Fitovinany, Anosy and Atsimo Andrefana.

UNICEF, Practica et EntrepriseWorks/VITA ont développé une mallette pédagogique à l’intention des pays africains souhaitant s’engager dans la professionnalisation du secteur du forage manuel. Cette mallette pédagogique comprend des fiches et manuels techniques, des éléments de plaidoyer, des cartographies des zones appropriées pour le forage manuel, des études de cas, et des manuels de formation et de mise en oeuvre. Cette initiative contribue à renforcer les capacités du secteur privé local de façon à répondre aux besoins en eau potable des zones rurales qui ne cessent de croître.
