Kolomo District Dam Project – Zambia
This project summary has been redacted for security reasons to omit the specific project location.
Xxxxxxxx Village, Kolomo District, Southern Province, Zambia
This past rainy season, Southern Province experienced higher water levels than had been recorded in the last few decades as a result of the El Niño climate weather pattern. In Xxxxxxxx, heavy rains and a flash flood caused a collapse of the dam’s spillway. Over 75 % of the collected water was lost, with the remainder insufficient for the needs of the community during the dry season.
The village is named after the dam because of the villages dependency on the dam. There is an extremely productive irrigation system and cooperative. Concrete furrows stretch out over into an irrigation unit covering 400m^2 which is fenced in and maintained for agricultural use.
There are community gardens and fish that cannot continue without the dam.
The pressure of the high rain levels created a sinkhole underneath the spillway that caused the entire wall to collapse. The spillway was responsible for holding in the water within the dam. With the destruction of the structure, all of the water rushed out in a span of a few days, leaving a low water level.
The first part of the plan is to remove the large pieces of rubble left behind by the collapsed wall. An excavator will move aside the destruction in one day.
The Department of Agriculture will help choose an expert contractor to design and build a new spillway that will be able to handle a strong force of water pressure in the future, so this disaster does not occur again. The community is already busy hauling stones from all over the area to the site for the construction of the wall.
Once the excavation is complete and the materials are present, the project itself can be finished in just a few weeks. Project funds will pay for the excavation machine to be brought to Xxxxxxxx, as well as for the cement, reinforced wire, wheelbarrows and equipment for crushing the stone, and payment to the contractor for his design and supervision.
Members of the community will haul and manually crush the stones, and build the wall.
200 people will benefit from the project.

Monitoring and Maintenance
The use of a highly experienced contractor to design and build the wall will ensure sustainability. Careful attention to the construction materials and techniques will ensure that new spillway remains stable and safe
