If I want to build a sand dam in my country/region, what's the first thing I should do? Every year we hold sand dam learning visits in southeast Kenya with our partners, Africa Sand Dam Foundation. If you'd like to learn about and see first-hand how sand dams work, please email [email protected] to find out more about a possible learning visit. You can also read our sand dam manual which will tell you everything you need to know about building a sand dam. Manage Cookie Preferences
