As mining activities expand across Africa, the focus on water stewardship becomes increasingly crucial. While many countries benefit from the growth in the mining sector, concerns persist about the impact on communities near mines, particularly regarding groundwater and surface water resources.
Ismail Mahomed, partner and principal hydrogeologist at SRK Consulting, underscores the importance of managing water issues, especially in regions like Africa’s copper belt, known for its rich mineral resources. “Effective water management is essential not only for complying with local regulations and global standards but also for maintaining a positive social license to operate,” he says.
Managing risks
Mine dewatering poses significant risks, particularly in areas with low rainfall, such as southern and northern Africa. Contamination of water resources remains a major concern, and there’s a growing expectation for mines to mitigate these risks and ensure a safe environment post-closure. Mahomed emphasizes the necessity of integrating closure planning from the outset, highlighting the zero-tolerance stance towards historical contamination.
Ethical supply chains
The push towards ethical and sustainable mining practices is intensifying, especially with the rise of copper and cobalt mining in countries like the Democratic Republic of Congo. As markets demand lower-carbon solutions, industry benchmarks like the Copper Mark are becoming vital. “Responsible sourcing, particularly for minerals used in battery and renewable energy technologies, is increasingly integral to supply chains, especially in markets like Europe,” Mahomed adds.
Enhancing sustainability
To effectively manage water resources, mines need specialized expertise to generate and analyze accurate data. Sathisha Barath, principal hydrogeologist at SRK Consulting, stresses the importance of using advanced data management tools to optimize water stewardship. “Focusing on quality data collection and interpretation, rather than just meeting compliance requirements, is crucial for developing a robust environmental management strategy,” she explains.
Advanced tools and models
Mahomed also points to the benefits of digital tools, such as numerical models and dashboards, for improving water management. These tools allow for real-time data access and more precise dewatering strategies. “Models should be based on site-specific data and continuously refined to ensure effective water management,” he says.
Setting meaningful targets
Barath advocates for a strategic approach to water management that goes beyond mere compliance. “By developing tailored solutions that align with a mine’s strategic objectives, we can avoid generic approaches and instead focus on cost-effective, long-term solutions,” she says. SRK Consulting’s Water and Environmental Technology (WET) team plays a critical role in helping mines across Africa with their water management challenges, leveraging their expertise in surface water and groundwater solutions.
In collaboration with other specialists in mining and environmental, social, and governance (ESG) fields, the WET team conducts due diligence, feasibility studies, and environmental and social impact assessments (ESIAs) to support sustainable mining practices across the continent.
