sanddam

A sand dam is a rainwater harvesting structure that is built across seasonal river bends in arid and semiarid regions.The structures are made of a structural wall that traps the sand from water flowing downstream, a shallow well which is fitted with a hand pumped a network of an underground infiltration system.

 

How Sand Dams Works


The sand dam structure(wall) is made of two basic parts,the spill way,and the two wings at each side.However, the dam may also require side protection walls and an apron depending on the nature of the soil at the site.

Extraction method


Soil Conservation through terracing2

Traditional scoop holes.

With the water nearer the surface,communities can now draw clean,sufficient water from the traditional scoop whole with a lot more ease than it used to be before the sand dams were constructed.

shallow wells

Hand pumps

Along with the Sand dam,ASDF supports the community with the construction of the shallow well which is then fitted with a hand pump for easier access of the water.

rock catchment

Solar pumping system

In some sand dams,we have been asssting the community access the harvested water a lot more conveniently by installing solar powered water pump which pipes the water to more central poits and much closer to the beneficiary homes.
