Remediation to Wetland
Randfontein, West Rand
The location consisted of a mountain of tailing dumps and non-operated gold mining. The project intervenes in its site with two aspects; first, clean up the tailing using a horizontal drainage system that is set to clean toxic soil. Second, constructing wetland adjacent to the tailing mountain. These two aspects connect by the drainage system from one to another.
The section presents horizontal drainages’ cleaning and stabilization technology for tailings ponds. By setting up the drainage structure, it is extended to be the foundation of urban settlement, an infrastructure from the remediation.
Toxic water that cleans up the soil pump and overflows into the wetland system. The drainage system link links to a constructed wetland within the surrounding site. Water flows in one end of the basin, moves slowly through, and is released at the other end, together with a deposition strategy in which soil is extract-ed from one area of the site and then deposited in another area. Having soil deposition within its adjacent – reshape the topography of the mining site for expansion of the green and agricultural area.
