Présentation
Scorching temperatures, an open sky, a shortage of deep wells and lack of water purification system make this a thirsty part of the world indeed.

"After the rainy season, water becomes scarce," says Mahamat Adoum Doutoum, chief of the Guerri region, where only two deep wells exist for 86,000 inhabitants. "So people go to look for water in the wadi."

Wadis—"riverbeds" in Arabic—are watercourses that run strong and fast during the rains and are often dangerous to cross, but largely dry up for the rest of the year. When there is no more rain, people dig wells in the wadis and install pumps to extract groundwater.

Ali and dozens of other water carriers flock to the pumps to collect supplies they plan to sell to people who have no access to the source, often in dusty settlements.

Each refill of his 200-litre drum costs Ali 100 CFA francs (0.15 euros / $0.17), but he can sell the water for five times as much in town. "We do between seven or eight return trips each day, roughly," he says.
