Sand dams are some of the most affordable ways to get water for communities through excarvation and construction of small dams in Kenya. Being one of the best dams construction company, most farmers have really benefitted from our innovations throughout East Africa.

Most of the rain water in East Africa goes to waste as there are not adequate measures undertaken to preserve this water in reservoirs. We therefore highly encourage residents to construct small dams and water catchments to maximise water storage initiatives and as a result protect the environment. The advantages of so doing are numerous.


We provide sand dams both for individuals and communal. Sand dams and small dams are a sure way of ensuring communities get water during dry seasons. Communities may come together to form informal groups which identify a committee with one objective of identifying a location for a dam site. The structures store water for livestock, irrigation and domestic use.

Although design and construction of sand dams in different areas shows some variability, as each site is different and the design has to be modified accordingly, all sand dams and small dams have a similar basic design. Water catchments vary in width and discharge, rock foundations vary in depth and susceptibility to leakage, riverbanks may be high or low. The location of a water pan should be chosen such that: it is feasible on technical grounds, it has high storage capacity, it has minimum cost and it is convenient to the community using it.

A sandy soil layer with sufficient water retaining capacity and the possibility to build up such a layer is important; the sand provides the storage space within the pores.


After excarvations, we can cover the sand dam/ earth dam with a dam liner strong enough to retain water collected, though this poses a challenge of desilting all the time.
