Located in the Karas region along the Fish River in the south of the country, the project is the first phase of the Neckartal Irrigation Scheme.
Made from roller-compacted concrete (RCC) and standing around 80 metres high, the Neckartal dam will harness water from the Fish River to produce energy and to create a reservoir capable of holding 857 million cubic metres of water, which will be used to irrigate 5,000 hectares of land for the agricultural development of the area.
A crossing and a pumping station, along with the relevant intake structure, will be built 13 km downstream from the dam. The water will flow through an 8.7 km steel pipe with a diameter of 1,100 mm to reach a reservoir that is also part of the project.
