Mobilize groundwater wherever it is available

What we propose: prospecting, mobilizing and managing aquifers sustainably. In many cities, this solution is the technico-economic optimum to ensure water supply. BCC has developed a particular expertise in karst aquifers, on which a third of the world's population depends for its water supply.

Some applications of this approach:

The islands of Lake Chad are inaccessible to construction equipment. Thanks to EU funding, BCC and Hydroconseil have built 18 manual boreholes on the islands, using artisanal drillers who transport their equipment by dugout canoe.

The capital of Gabon (Libreville) is built on a peninsula where water resources are brackish. Hydroconseil has mobilized Bernard Collignon's hydrogeological expertise to design and develop two high capacity well fields (30 000 m3/day each) 

The city of Tlemcen is located at the western end of the Algerian Atlas, the driest. It is in the subsoil of its limestone mountains that the most important water resources are hidden. Bernard Collignon has developed for ANRH a model of rational exploitation of this resource by a hundred of drilling, which allows to limit the impact of the most severe periods of drought

On the bangs of the Sahel and Sahara, pastoral livestock is the main economic resource for millions of households. Shepherds draw water from deep wells by harnessing their animals. Bernard Collignon has designed a tool to exploit satellite images of livestock tracks to map water resources.

The capital of Guinea (Conakry) lies on a long peninsula of magmatic rock. Water distribution is very uncertain and half of the population relies on 40,000 private wells and boreholes. BCC has developed a model of the peninsula's aquifer to simulate the impact of these numerous structures and the predicted response of the aquifer to climate change

What others do better: engineering large dams and water treatment plants
