DRA Global was contracted by Glencore to provide holistic water treatment solution for their operation at Tweefontein.  With extensive experience in mine water reclamation, DRA has constructed a 15MLD mine water treatment plant comprising of a 2-stage membrane process with inter-stage softening. A state-of-the-art brine treatment plant concentrates the unrecovered water from the primary mine water treatment plant, economically reducing storage requirements.

A potable water supply of 10,000 m³/day is generated by mineralizing and chlorinating the permeate stream. The product water complies with SANS drinking water standard and is supplied to the local municipality.

Apart from the treatment plant, the project included supporting infrastructure such as water retaining structures, offices, control room, laboratories, change houses, and workshops
