What is a sand dam? A sand dam is a reinforced concrete wall built across a dry riverbed, which when it rains, forces some water underground, filtering it clean, protecting from mosquitoes and snails, and preventing evaporation. A simple piece of engineering that will alter the lives of the communities around it forever.
In the middle of the drought currently affecting East Africa, the Water Relief work we support in Kenya is all too necessary. In the words of 2011 volunteer Heather McCollin, "Seeing the results and the changes in the environment around sand dams that were only one or two years old was amazing. Imagine what a difference the dams will make in future years!"

It appears that eventually the silt and sand reaches the top of the up stream side of the dam. Doesn't this have to be periodically cleaned out for this method to continue working?
