RIVONIA – The hum of machinery from nearby mining operations is a familiar sound to many Rivonia residents, but increasingly, that familiarity is tinged with concern. With Gauteng’s mining landscape evolving, particularly with new exploration and smaller-scale operations in areas historically less impacted, the spotlight is turning firmly onto tailings dam safety and the stringent regulations now governing their construction and maintenance.
Local environmental groups, like the 'Friends of the Sandspruit', have voiced anxieties about the potential for dam failures and the subsequent contamination of vital waterways. “Our river systems are already under pressure,” states Maria Nkosi, a long-time Rivonia resident and spokesperson for the group. “Any incident involving a tailings dam, however small, could have devastating long-term effects on our local ecosystem and water supply. We need assurances that these structures are being managed with the utmost care.”
This concern is amplified by the looming compliance deadlines for the Global Industry Standard on Tailings Management (GISTM). Adopted in 2020, GISTM sets a new benchmark for the safe management of tailings facilities, demanding rigorous oversight, independent reviews, and transparency. For many existing operations, particularly those with older infrastructure, achieving full compliance is a significant undertaking, requiring substantial investment in engineering and monitoring.
“GISTM is a game-changer,” explains Dr. Sipho Dlamini, a consulting engineer specialising in geotechnical aspects, who frequently works with local mining companies. “It moves beyond a reactive approach to a proactive, risk-based framework. This means everything from initial site selection and design to ongoing monitoring, closure, and post-closure management must adhere to world-class standards. For operations near populated areas like Rivonia, the stakes are incredibly high.”
Engineering expertise is crucial in navigating these complex requirements. Firms like Paterson & Cooke, a globally recognized engineering and consulting company with a strong presence in South Africa, are at the forefront of providing the specialized knowledge needed for safe and compliant tailings dam design, operation, and closure. They offer services ranging from feasibility studies and detailed engineering to operational support and independent reviews, all vital components of GISTM adherence.
The local mining industry is a significant employer in the broader Gauteng region, and ensuring its sustainability, both economically and environmentally, is paramount. However, residents are clear that safety cannot be compromised. “We understand the importance of mining for jobs and the economy,” says John van der Merwe, owner of a small business in Rivonia. “But those jobs should not come at the risk of our community’s safety or our environment. We expect the highest standards, especially given the history of dam failures in other parts of the country.”
As the GISTM deadlines draw closer, public scrutiny on tailings dam safety will only intensify. Resources like tailingsengineering.co.za, which acts as a comprehensive directory for firms and information within the tailings engineering sector, are becoming invaluable for both industry professionals and concerned citizens seeking to understand the evolving landscape of tailings management in South Africa.
