Sand Dams - Build project at Kwainyoe, Kenya.

Sand Dams were invented by the Romans some 2,000 years ago, to provide clean water for the territories they conquered in Europe and beyond.

Their use has now become a staple supply of safe clean water in many arid areas of Africa. The dams are built by village self-help groups on dry river beds.  The dams fill with sand over a couple of rainy seasons and this helps store water and filter it.  Safe drinking water can then be drawn off for human & animal consumption and in many places to provide irrigation for crops.  This produce is either sold or used locally to help sustain the village.
