Hit at the end of August 2020 by heavy rains, Niamey spent the end of the summer under water: more than 350,000 people were affected. In the face of this situation, the Veolia Foundation took action. A team of Veoliaforce volunteers arrived at the scene on September 14 and nearly 11 metric tons of humanitarian aid supplies were dispatched in just a few days. Within 48 hours, thanks to the work of SEEN (Soci_t_ d�Exploitation des Eaux du Niger) and Foundation staff, three Aqua forces 5000 mobile water purification units were ready to be used. The quality of the water produced was checked using bacteriological analyses, and distribution began on September 18.
