Engineering company commended for AMD treatment plant design

Engineering consultant Aecom received a ‘Highly Commended’ citation at Construction World’s 2016 Best Projects Awards for its work on the Eastern basin acid mine drainage (AMD) treatment plant commissioned by State-owned water infrastructure developer Trans-Caledon Tunnel Authority (TCTA). The AMD plant services a surface area of about 768 km2, comprising a catchment area that stretches from roughly Modderfontein in the north to Springs in the east, Nigel in the south and Germiston in the west. The plant itself is located in Springs. It is one of the largest high-density sludge plants in the world, with a maximum treatment capacity of 110-million litres a day.
