Concor Civils, a Murray & Roberts Construction company, has begun earthworks on a contract awarded in May this year by Johannesburg Water to construct a new 20ML water reservoir and a 1.2ML water tower in Lanseria. The contract includes minor building works, such as a guardhouse and telemetry house.

Designed by Worley Parsons, the reservoir is 53 m in diameter with a wall height of 10 m and a flat slab roof, and the elevated water tower is 25 m high with a tank diameter of 26 m. The project will require 3 400 cubic metres of concrete and 400 m of primarily steel piping in total, as well as 9 000 square metres of formwork and 300 t of steel reinforcing. The piping will link into an existing water line running on the edge of the reservoir.

“Our company has established an excellent reputation based on our capabilities within the water and waste water sectors, and especially our ability to construct water retaining structures to high specifications,” Arie Nijhuis, Concor Civils’ project director, says. “We’re drawing on the same expertise used at the Zeekoegat Waste Water Treatment works near Pretoria and the Driefontein Waste Water Treatment works in Johannesburg.”
