Madagascar, Ampasindava, Drinking water access


This project is part of a decentralized cooperation between the department of Finistere and the DIANA region in northern Madagascar. It aims to supply the village of Ampasindava with 1,000 inhabitants with drinking water and to improve the sanitation situation there. Indeed, the population of this village feeds itself with drinking water from two small wells with totally unhealthy water. The development of a water network will not only improve the lives of people on the ground but also initiate income-generating activities such as local tourism.

This development is supported by the ongoing construction of an electricity grid, but is constrained by access to drinking water that is largely insufficient. The project aims to support the economic and social development of the locality by setting up basic water and electricity services, by supporting the development of alternative tourism, entrepreneurship through strengthening and adapting training schemes. In terms of access to drinking water, the objective is also to satisfy needs in a sustainable way by setting up a sustainable management system.


A hydrogeological and hydraulic reconnaissance mission and preparation of the recruitment file for a prime contractor for the Ampasindava drinking water supply project was carried out on 25 and 26 January 2017 in the company of Nicolas Livache - Experts -Solidaires and Mr. Armand, Engineer DREAH Diana.


The waters of the Ampasindava wells are brackish or will not allow the necessary flows to be mobilized. The capture of water from the hydrographic network or from groundwater recharged by the hydrographic network outside the influence of marine intrusions is necessary.

Two south-north flowing streams fed from the Amber Mountain are identified around Ampasindava:

  • The Ampahiry / Vinany about 3 km south-south-east of Ampasindava
  • The Ambararata, just above the town of Antanamandriry, about 5.7 km south-south-west of Ampasindava

The objective is to find a resource with little mineralized water, little turbidity, in sufficient quantity, less distant than the capture of Mangaoka, and if possible allowing a gravity flow.

Two capture options are possible:

  • Option 1: a well captured on the right bank of the watercourse
  • Option 2: a water intake in the river from a concrete sill.


The first phase of the study is funded by the Conseil Départementale du Finistère.
