Madagascar, Mantasoa, drinking water project in the suburb of Anjozoro


This project aims to establish a drinking water network in the fokontany of Anjozoro and to improve the sanitation of this traditional Malagasy village. It is a decentralized cooperation project between the commune of Mantasoa (Madagascar) and the town of Auch (department of Gers, France). The project also includes an awareness campaign on hygiene, water use and sanitation.

In Madagascar, the rate of access to drinking water is estimated at 46% (according to UNDP, 2015), of which 74% in urban areas and only 26% in rural areas. In the municipality of Mantasoa, only the chief town has a drinking water network. In the fokontany of Anjozoro, the water supply is mainly from wells and springs which dry up in the dry season and the water is dirty during the rainy season (from November to April). Part of the population uses irrigation canals that are polluted by the use of chemicals in the cultivation of rice and bananas. Picked water is kept in jars protected by lids that residents strive to clean once a week.

The fokontany of Anjozoro comprises 5 villages and has 2,200 inhabitants in 2015. By 2030, the population can be estimated at 3,330 inhabitants. The population lives mainly on rice, and bananas and livestock are also produced.
