The "kasria" at Ouled Said. This is form the web: "Ouled Said oasis in Algeria is a human-made wetland covering an area of 25,000 hectares and is the center of date production in northern Africa. Inhabitants of Ouled Said maintain an ingenious an ancient system to capture and distribute groundwater. The system, called a foggara, works through the network of channels that flow within the oases. Water is brought to the surface and distributed through an ancestral social organization tool called the kasria. The kasria is a perforated plate inserted vertically into an underground chamber to bring water to the surface. The water is divided into channels of different sizes that run to individual gardens. The amount of water is controlled by the size of the hole in the kasria and corresponds to the need of individual families.
