The Wadi Dalal refugee camp of Gaga is about 60 km east of Abéché, and was recommend by RTI because of its exceptional combination of a thick alluvial aquifer structured by open fractures, leading to high and sustainable yields with vertical annual recharge.
Optimized thanks to the
WATEX™ study, drilling confirmed that the thick, high-quality gravel reservoir was fed by a large volume of water. In February 2005, UNHCR’s drilling partners (OXFAM) confirmed RTI’s prediction with
3 successful exploration wells drilled in March 2005.
Based upon the actual well productivity, the UNHCR announced in May 2005 its plans to
resettle up to 30,000 refugees to the new Dalal Refugee Camp.
