About the initiative
The project NOEVA (Nouvelle approche pour l’eau des Villes Africaines) use of complementary geophysics to increase knowledge of the groundwater resources in Benin.
This cost-effective approach also helps building capacity of the stakeholders responsible for local water resources management.
The goal was to develop a new approach to manage and sustainably consume groundwater resources by populations living in African coastal cities.
The first estimation showed that the groundwater volume of the Mio-Pliocene aquifer in Benin can supply the entire population of the Greater-Cotonou (about 1.5 million people) with 100 litres per day per capita for more than a century.
A borehole and a 3-day pumping test cost about eight times more than a geophysical survey.
The geophysical devices provided an accurate estimate of the Mio-Pliocene aquifer’s geometry.
