Project Background
An Earth Dam, is a dam built up by compacting successive layers of earth, using the most impervious
materials to form a core and placing more permeable substances on the upstream and downstream
sides. A facing of crushed stone is used to prevent erosion by wind or rain, and an ample spillway. Most
have a central section or core composed of an impermeable material to stop water from seeping
through the dam. The core can be of clay, concrete, or asphalt concrete. This dam type is a good
choice as they can be built on hard rock or softer soils.

World over, the impact of climate change has been severe in the recent past years with increased
cases of droughts and decreased rainfall. Zambia has had its own share of climate change effects with
reduced rainfall in most part of the country among many other. This impact has affected the agricultural
sector severely with experts in the field advising farmers to grow drought resistant crops. It is against
this background that efforts are been made to utilize every drop of storm water maximally and efficiently
through water harvesting techniques, the quest Ibamba Ranch Limited intends to undertake by
constructing the Earth fill dam.
