Bafokeng Rasimone Mine Grey Water Re-Use Plant

Challenge

Local water sources are often limited, and the cost to import water from distant external sources is high. Identifying local effluent resources, which are generally considered a waste product, can be converted to a product, with minimal effort, suitable for a variety of mine water applications. Municipal water reuse is a significant opportunity for mine water resource expansion.

 

Solution

The project comprised of several projects phases over several years and included the following:

  • Water balance assessment and WCDM strategy.
  • Dynamic water balance.
  • Conceptual and detailed design of Phase 1 (grey water) and 2 (potable water) water reclamation plant.
  • Shaft infiltration pumping stations (north and south) conceptual design and tender documentation.
  • Tender documentation for Phase 1: Reclamation plant.
  • Construction monitoring of north and south shaft dewatering pump stations and phase 1 reclamation plant.

The plant is currently saving BRPM about R8 million per year.
