The Neckartal Dam

The Neckartal Dam

31st January 2015

The proposed Neckartal Dam has a catchment area of 45 365 km² with a calculated average annual runoff of 397 Mm³/a. The wall will be made from roller-compacted concrete (RCC) and standing around 80 metres high with a wall crest length of 480 m.

The storage volume is expected to be 856 Mm³ and the full supply area may cover 39 km².

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

  • Open excavations: approximately 700,000 m3
  • Concrete (including RCC): approximately 1,075,000 m3
  • Embankments: approximately 250,000 m3
  • Steel reinforcement: approximately 7,000 tons
  • Formworks: approximately 115,000 m2

 

On completion it will be the largest water storage dam in the country and about 3 times the size of the Hardap dam, being presently the largest dam in Namibia.

The proposed Neckartal Dam site is situated in the Fish River approximately 25 km north of Seeheim and 40 km west of Keetmanshoop.

The dam will provide water for the irrigation of approximately 5 000 ha of land to the north and south of the Keetmanshoop to the Seeheim tarred road.

The Italian company Salini Impregilo, responsible for the construction of the Neckartal Dam, has reassured Namibians during December 2014 that the project is on schedule.
