Kashimbila Dam
Construction of a new multi-purpose 40-Megawatt dam in Taraba State, Nigeria will generate much needed electricity for the country and provide job opportunities, social and economic benefits to people in the area.
The preliminary design was for a dam with a storage capacity of 200 million m3 but this was subsequently increased to 500 million m3.
The main challenges were related to the lack of data in the hydrological and geological studies as well as the project location in the extreme south-eastern part on Nigeria, which required long travel times on very poor roads.
The hydropower station was initially designed with an installed capacity of 18 MW, however, following detailed hydrological modelling and yield analysis carried out by Aurecon, a 40 MW installed capacity was implemented. Aurecon’s input on this project led to a more economical design of the dam and an increased installed capacity for the hydropower station.

Monitoring
Liquid Level Settlement plates were installed at various levels within the embankment dam as the fill material was added. Together with VW Piezometers to monitor the pore pressure, these would provide a good picture of what was happening within the dam fill material during construction.
Geosense Technicians have recently returned from on-site assistance and training provided to the local site team for the Settlement Cells and VW Piezometers.
