Sand Dams, Climate Change, and Hope
Organization information
Hifadhi Africa Organization (HAO)

Summary
A sand dam is a reinforced concrete wall built on bedrock across a seasonal sandy river to collect water and sand during the rainy season and store it for use during the dry season. When it rains, the dam captures soil-laden water behind it - the sand in the water sinks to the bottom, whilst the silt remains suspended in the water. HAO has found sand dams to be the most cost-effective method of water harvesting, conservation and recharging in dry land and very remote environments.
