Winner: Ingula Pumped Storage Scheme
The multi-billion rand Ingula project is a peaking hydro-power station comprising an upper and lower reservoir separated in elevation by 480 metres within the Little Drakensburg mountain range. This project involving Gibb, Royal HaskoningDHV and Knight Piésold as the consulting engineers, has already contributed to stabilising the South African power system. When complete, it will house four 333 megawatt Francis-type pumps or turbines and motor generators in its underground powerhouse complex 116 storeys underground.
Commendation: Rehabilitation of the N2 from Umlaas Canal to EB Cloete Interchange
The 14 kilometre section of the N2 from the EB Cloete Interchange, southwards to the old Durban Airport is due to be fully upgraded within the next few years. In the interim, however, SANRAL required the cracked surface to be reinstated. Although the project was initially only for the reinstatement of the asphalt surfacing layer of up to nine lanes, this was extended to include the ramps and crossings at two major interchanges. The professional team comprised Naidu Consulting and Murray and Roberts Infrastructure.
Commendation: Ashley Drive Break Pressure Tank
The Ashley Drive Break Pressure Tank in Hillcrest, Durban limits water pressures in eThekwini Municipality’s Western Aqueduct to 25 bar so that the potentially destructive energy in the pipeline can be safely and economically controlled. Maximum operating pressures had to be mitigated by ‘reverse engineering’, devising a unique inlet system that could avoid overpressure and overflow under the most rapid system changes. With Knight Piésold, Naidu Consulting and Royal HaskoningDHV, the BPT’s operating system was designed by first principles since there is no known similar modulating system for large BPTs.

Battling challenging terrain and weather conditions, Aurecon and China Geo-Engineering Corporation International saw that the route now provides all-weather access to the general public in standard vehicles.
Commendation: Kasane-Kazungula Villages Sanitation Project
A R586 million combined gravity and vacuum-based system improved the sanitation system in the northern part of Botswana in two villages which form an important tourist hub.
