Excellent Development are Sand Dam experts.

Since 2002 we have enabled rural, dryland communities to build 988 sand dams in around the world.

Sand dams transform lives. They provide a sustainable, clean, local source of water for rural communities, saving time and creating opportunities for farming, education and poverty alleviation. By breaking the cycle of dependence Sand Dams create choice; freeing people to realise their own potential.

A sand dam is a reinforced concrete wall built across a seasonal river. They can store up to 30 million litres of water in sand. By trapping water within sand, it is protected from contamination and disease.

Sand dams are the most cost-effective method of capturing rain water in drylands.

For information on sand dams, sand dam volunteering opportunities and sand dam fundraising ideas, look no further than Excellent Development. We want you to become a sand dam pioneer too. Together, we can pioneer sand dams in drylands worldwide and transform millions of lives.
