Sustainable well in Senegal

A humanitarian project by Balouo Salo to allow access to drinking water in a rural African village

Location: Sanofily Village, Sedhiou Region, Senegal
Beneficiaries: 3,000 people
Construction: BALOUO SALO Charitable Organization, Beneficiary Community
Project: BALOUO SALO, Raoul Vecchio, Mamath Ndiaye
Purification plant: Sorgiva Farm

Sanoufily is a small village in the Sedhiou region (Senegal), of about 800 inhabitants, flanked by the villages of Kindombalicounda, Bissary, Malandiacounda and Boraia. Here there are very few wells and these are traditionally dug not reaching the underground water table but rather deposits that empty quickly, causing serious problems with water supply.

The phenomenon of saline intrusion, due to climate change, has caused acidification and contamination of the subsoil and the aquifer, the consequence of which is the presence of contaminated and salty water in the wells.

The weakest subjects such as children and the elderly are at risk, 60% of the diseases are due to water, the risk of infections, giarda, cholera is high. The region has the highest number of infant mortality in the country, and this is also due to the poor availability and quality of water.

The well was built and donated by the BALOUO SALO Charity Organization and consists of a modern well (with over 8 meters of water column) that reaches the aquifer to allow the community to be able to draw on the water resource at any time of the year. year. But the fundamental element is the filtering system consisting of a sand pre-filter to eliminate sediments, a UV sterilization filter and an osmosis filter, to eliminate viruses and bacteria. The water, on the other hand, is withdrawn by means of an immersion pump powered by solar energy.

The purified water will then be discharged into two tanks that will store the water indoors and in the shade to maintain its quality, and which will be accessible at any time of the day. Thanks to this system, the community will be able to have highly drinkable water for the health safety of families, but especially of children, pregnant women and the elderly, as weaker subjects often affected by viruses present in the water of traditional wells.

The well is also accompanied by a symbolic and representative architecture that aims to give value to the water resource and create a place of sociality around the well itself.

The project was carried out under the direction of the architect and humanitarian activist Raoul Vecchio, president Balouo Salo, with the accompaniment of the Senegalese team of Balouo Salo managed by Mamath Ndiaye, but above all with the participation of the beneficiary community. Balouo Salo, in fact, carries out each project together with the community to encourage the appropriation and sharing of knowledge in order to give sustainability and self-sufficiency to the projects.

The occasion of the realization is in fact also that of sensitizing the community on the use of the water resource and forming a local team on the maintenance and management of the filtering system.

There are over 3,000 beneficiaries from not only Sanoufily, but also from neighboring villages. The system represents a real technological innovation for Senegal and aims to be a humanitarian model to promote accessibility to water, as a fundamental element for life and public health.
