Creating clean water storage in dry lands, using local resources and creating sustainable futures

Excellent Development

Sand dams are the cheapest method of rainwater harvesting in drylands. They provide communities with a clean, local and reliable source of water – even during periods of drought.

Sand dams store up to 40 million litres of water and provide a year-round supply for up to 1,000 people – with virtually zero operation and maintenance costs.  By storing water safely within sand, sand dams protect it from contamination, evaporation and parasites – cleaner water that lasts longer.
