Feasibility mapping for low-cost water technologies

The major part of Madagascar’s population lives below the poverty line and access to clean drinking water is only 38%. As a result diarrhoeal diseases are the third leading cause of morbidity and contribute to 50.9 % of infant and child mortality.

The implementation of new technologies could be a solution to reduce costs and increase access to drinking water for the rural population. PRACTICA conducted a mapping with GIS technology to identify favourable areas for low-cost drilling and pumping technologies.


  • Increasing access to safe drinking water and sanitation in rural areas of Madagascar.
  • Capacity building of small local contractors to deliver products and services that increase access to potable water.
  • Promoting combinations of multiple technologies to install manually drilled boreholes with hand pumps.


  • Definition of the scope and limitations of low-cost technologies (collection, analysis and processing of information prior to mapping)
  • Analysis and data processing of the AED identification of geology favorable to low-cost technologies.
  • Mapping the population located in zones favorable to low-cost technologies.
