About the Program

Sand dams are the most cost-effective solution to the ongoing cycle of drought in the Horn of Africa region. Sand Dams capture millions of liters of rainwater and store it underground. One Sand Dam can provide up to 1000 people with drinking water for up to a year without rainfall.

Why Sand Dams
Over the past few decades, the Horn of Africa region has been known to have recurring droughts. And now with climate change and the El Niño weather pattern, you have both extremes; droughts, and floods. For many parts of this region, there is little to no infrastructure to contain the rainwater, and surge of river. So when it rains and there is a surge in the river, much of that is lost to the ocean.

Sand Dams can…

  • Combat desertification by recharging groundwater.
  • Mitigate climate change by creating water security.
  • Reduce conflict by increasing access to water.
  • Support disaster resilience by creating a buffer against drought.
  • Enable the installation of shallow wells producing safe drinking water.
