West Africa’s water supply is unevenly distributed and poorly accessible due to undeveloped water supply systems, and crosses national boundaries, creating significant management challenges. 90% of water supply in Mauritania comes from outside the country. Furthermore, surface water is limited and often seasonal, making groundwater a primary source of water for many people in the region. Limited infrastructure in the city results in poor quality drinking water. In urban areas, intense precipitation is likely to impact the water infrastructure, as the increased volumes of water overwhelm sewer systems and water treatment plants. This could also lead to an increase in the amount of runoff into rivers and lakes, washing sediment, nutrients, pollutants, trash, animal waste, and other materials into water supplies making them unusable, unsafe, or in need of water treatment and increasing cost for water purification to supply potable water to communities.
