Support us Join an expedition About our expeditions February 2026 sand dam expedition with Koy Clothing In February 2026, a group of volunteers teamed up with Sand Dams Worldwide, Koy Clothing (an ethical and sustainable clothing brand) and our local partner, Africa Sand Dam Foundation (ASDF) to support 'Ngiluni-Utuneni Earth Dam' self-help group and their community in southeast Kenya to build a sand dam. The sand dam was funded by Koy Clothing and their wonderful customers, and will go on to provide the community with a local lifelong supply of clean water.
