Bafokeng Rasimone Mine Grey Water Re-Use Plant
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.
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.
- Feasibility studies.
- Project management.
- Water balancing assessment and WCDM strategy.
- Water balancing.
- Conceptual and detailed design of plant.
- Tender documentation and construction supervision.
- Environmental protection and reduction of pollution to surrounding areas and water systems through water re-use.
- Localised job creation.
