Sand Dam Inspiration from Kenyan Self Help Group Perspiration




Can you imagine taking 4 to 6 hours of your day to get water and then bring it home?



The rainy season in Kenya is 

March to May 

and 

November to December 

but the amount 

of rainfall varies year to year. 

Many streams dry up in the "dry seasons."


The yellow containers keep the water moving.



How about building a sand dam?  
Build a dam in a stream.
The upstream side fills up with sand.  
The sand becomes a "water tank" to hold water in the volume of the sand, 
60% water 40% sand.




Dig down in the sand.  
In a few seconds the hole has water ready to be dipped out.












The sand dams are built in two phases.  The first one is five foot tall.  The second is another five foot on the first phase.



The downstream side still has water available.


About 2% of the water flowing down the stream is held back with minimal impact on the downstream ecology.



Looking up stream, there's a lot of sand which equals a lot of water!
The shady spot on the upper left contains a hole dug down in the sand to be a regular water supply for people and animals.


The road passes right over the top of the sand tank.


The future seed bank building made from bricks that used water and clay from the sand dam then built by the local self help group.

Benefits of Sand Dams
       Water for humans – cleaner
       Water for animals
       Water for plants – raises water table
       Vegetables & fruit to sell
       Resolves water conflicts
       Brick making
       Stops erosion
       Travel time to retrieve water is drastically reduced

The local self help group will provide sand, stones, labor, food and child care during the construction.  Utooni provides the site study and engineering.  Mennonite Central Committee and other non-governmental organizations provide cement, rewire and re-bar.

The staff at Utooni taught us so much about the vision and development of sands dams!

The next time you get water out of your faucet pray for the people of the world working to get water supplies available to more residents of this earth.

Thanks so much for the inspiration to help life to flourish.
