| Abstract |
The Dikgatlhong Water Project is a massive project by any standards, with an overall estimated value of some R2.4 billion. The Dikgatlhong Dam, the raw water transfer system and the associated infrastructure will ultimately deliver an additional 3 000 litres per second of raw water into the existing national north–south carrier pipeline that transports water over 400 km from the Letsibogo Dam near Selebi Phikwe to Botswana’s capital, Gaborone.
With a full supply storage capacity of 400 million m³, the dam, which is located 65 km northeast of the town of Selebi Phikwe and a few kilometres below the confluence of the Shashe and Tati Rivers
in north-eastern Botswana, is the largest in Botswana, which makes its impact on that country immensely significant.
It was designed and constructed for Botswana’s Department of Water Affairs in anticipation of a growing demand for water due to increased mining activities – the major contributor to Botswana’s
economy – and an expanding population in eastern Botswana.
In joint venture with Bergstan Botswana, and Gauff of Germany, Jeffares & Green’s Pietermaritzburg branch undertook the preliminary design review, detailed design, tender documentation
and procurement process, contract administration, and the construction supervision of the full project.
Following the two-year detailed design and tendering period, the construction of the Dikgatlhong Dam started in March 2008 and was completed in early 2012. |
