Engineering News reports that the Trans Caledon Tunnel Authority (TCTA) has invited applications for the construction of infrastructure for the Witwatersrand Eastern basin AMD project, near Springs.
The development of project infrastructure to extract and treat acid mine water – as part of efforts to mitigate the decant of acid mine drainage (AMD) in the Witwatersrand basin – and then convey the treated water to nearby water sources, was scheduled to start in late 2013.
The project will involve, inter-alia the construction of shaft capping for Grootvlei Shaft No 3; building a structural steel pump station superstructure
, including foundations; the procurement and installation of three deep-mine abstraction pumps; the construction of a 106-million-litre-a-day high-density sludge treatment plant; and the construction of a motor control room building, generator room and several short pipelines. Roadworks and fencing and the supply and installation of medium- and low-voltage switchgear and other electrical components will also be required.
The project is aimed at employing a short-term solution
to AMD in the Western, Central and Eastern basins of the Witwatersrand goldfields, with the primary objective of halting the decant in the Western basin and preventing the breach of environmental critical levels (ECLs) in the Central and Eastern basins, writes Engineering News.
Water and Environmental Affairs, courtesy of the registered taxpayers, will pick up the bill of this first phase at R225 million over two years.
