NECKARTAL DAM, NAMIBIA

A fundamental project to bring water to the Namibian desert, and irrigate 5,000 hectares of land, stimulating agriculture and creating jobs. The Neckartal Dam on the Fish River is of immense value to the entire Namibia.

Located in the south of the country, it constitutes the first phase of the Neckartal Irrigation Scheme (NIS), which aims to irrigate for the agricultural development of the area.

Inaugurated in March 2020, the Neckartal Dam is situated about 40 km west of Keetmanshoop and is a curved gravity dam. Made of roller-compacted concrete (RCC), it is about 80 meters high, 518 meters long at the crest. The project utilizes the waters of the Fish River to produce renewable energy and create the largest water reservoir in the country, with a capacity of 857 million cubic meters of water. The project also included the construction of an intermediate weir (360 meters long and 9 meters high) located 13 kilometers downstream, a pumping station, a steel water pipeline (1.1 meters in diameter and about 10 kilometers long), and a containment dam to create a 90,000 cubic meter storage basin.

During the implementation of the project, 5,500 jobs were created, of which 3,000 were direct and about 2,500 indirect, 65% of which were from the Karas region. The project marked an important safety record for the southern Africa region, with over 1.1 million hours worked without incidents.
