Identification of aquifer potential in Central Darfur over an area of 135000 km² has been achieved by Radar Techologies France, USGS and UNESCO in 6 months.  The study was funded by USAID OFDA

The area is the home of most of the IDP’s camps, hosting 2.5 million people, where security is a major concern.

Such identification was made possile using the WATEX process based on new radar remote sensing technologies developed and patented by RTF.

This process combined with optical remote sensing, geology , geomorphologic features and climatic data, revealed significant buried aquifers not visible from the surface.

The study has revealed vast stretches of land in central Darfur hosting enough ground water reserves to sustain 33 million people year round with 15 litres of water per day (according to Sphere Humanitarian Charter Standards).

These aquifers are renewable and easily accessible within a depth ranging from subsurface to 50 meters in unconsolidated sediments easy to drill.

Ground Penetrating Radar (GPR) operated by RTF over some aquifers, confirming their depth and structure up to 40m deep. Drilling results collected in Sudan have confirmed the validity of the results with a success rate of 95% on 740 wells and boreholes.

 Potential water drilling sites map and drilling manual have been produced and given to NGOs, UNESCO and UNICEF.
