While rain is vital for replenishing water resources such as lakes, rivers, and aquifers, which are essential for both human and ecological survival, heavy rainfall can pose significant challenges for surface mines and their quarrying counterparts, potentially leading to flooding, operational disruptions and increased costs.
That is exactly the situation in KwaZulu-Natal, a province that has experienced prolonged rainfall patterns and resultant flash floods in recent years – a trend which has become the new normal and is attributed to the pressing effects of climate change. In fact, KwaZulu-Natal has experienced 12 devastating floods over the past nine years, to the detriment of both households and businesses.
This year has not been any different, with Durban, the metropolitan capital of the province, exceeding its average annual rainfall of 1 009 mm within the first four months of 2025, according to the South African Weather Service (SAWS). This equates to approximately 69 mm of rain per month.
Requiring effective solutions to mitigate the impact of excessive water accumulation in pits and desilting settling ponds, quarries and mines operating in the province are taking advantage of the comprehensive and flexible dewatering and dredging solutions from IPR, now part of Atlas Copco’s Specialty Rental Division.
Extensive footprint
Herman van Rooyen, business development manager KZN at IPR, says that by leveraging Atlas Copco’s extensive provincial footprint, advanced logistics and technical prowess, IPR has proven to be the dredging and dewatering specialist of choice for operations operating in the region. Offering both the correct product and the right expertise, the company is playing an integral role in keeping mining areas free of flooding.
“IPR’s integration into Atlas Copco’s Specialty Rental Division, better known as Rand Air in South Africa, has significantly enhanced our offering, not only in KwaZulu-Natal, but within the southern African region at large, by providing access to a broader range of equipment, advanced technology and a stronger service network,” he says.
“Quarrying and surface mining operations now benefit from a more comprehensive and reliable rental solution that not only meets immediate dewatering and dredging needs but also offers cost-effective solutions to support long-term growth and success. Through Rand Air, we have professionals in each province, bringing us even closer to our customers and servicing them more effectively,” adds Van Rooyen.
Why IPR?
In quarries and surface mines, water accumulation – whether from rain, groundwater seepage or both – can wreak havoc to operations through flooding of mining areas, structural and equipment damages, as well as health and safety hazards. Dewatering, says Van Rooyen, therefore plays a crucial role in preventing flooding and keeping site operations running smoothly.
“While it is true that the selection of a dewatering pump largely hinges on application requirements, we believe that the principal consideration should always be the expertise of the supplier, which is why many operations in the KwaZulu-Natal area prefer IPR for their dewatering and dredging needs,” says Van Rooyen. “IPR provides quality pump solutions and dewatering equipment, playing a key role in supporting dewatering efforts for quarrying and surface mining operations.”
IPR, he adds, offers a versatile range of products that meet the dewatering and slurry needs for quarrying, surface mining and industrial operations. These include Atlas Copco diesel self-priming and submersible pumps, as well as Toyo heavy duty slurry pumps. The Atlas Copco submersible pump range for dewatering starts at 0,4 kW to 65 kW, while the Toyo heavy duty slurry pump offers ranges between 2,2 kW and 450 kW, depending on application.
Where constant pump relocation is a principal requirement, IPR’s skid or trailer-mounted dewatering pump solutions offer the benefit of ease of mobility. These systems can be easily installed in open pits and be moved across different areas of the mine, adapting to changing conditions and requirements.
This is complemented by the in-house designed IPR SlurrySucker dredging system, which is suitable for the regular cleaning of process water ponds, return water dams or other water storage areas. It is also ideal for dredging and cleaning water capture areas where silt or slimes are an issue or where water retention and water holding capacity are being threatened.
“From diesel-driven pump sets for heavy-duty applications to electric submersible pumps for more energy-efficient dewatering, and the SlurrySucker for specialised dredging, IPR provides tailored solutions that ensure smooth water management and slurry removal activities. With our flexible rental options, high-quality equipment and 24/7 support, we are well-positioned to meet the challenges faced by the mining and quarrying industries in the KwaZulu-Natal region,” says Van Rooyen.
Perfectly matched
Before selecting a pump for dewatering needs, Van Rooyen reiterates that it is important to assess site-specific conditions. By combining detailed site assessments, expert recommendations, customised solutions and continuous support, IPR ensures that each dewatering or dredging solution is perfectly matched to the specific conditions of the quarry or mine site.
“This tailored approach helps maximise efficiency, maintain safety, meet environmental standards and minimise operational downtime. Whether it is handling heavy slurry, managing high flow rates, or operating in remote areas, our diverse range of equipment and expertise guarantees that each solution is the right one for the job,” he says.
Rental flexibility
In an environment where capital is not always available, IPR’s flexible rental model makes sense for quarries. Renting pumps from IPR eliminates the need for substantial upfront capital expenditure, freeing up capital for other pressing operational needs. In addition, says Van Rooyen, renting pumps provides unmatched flexibility and scalability for mining operations.
“IPR’s flexible rental model is designed to meet both short- and long-term needs by offering access to advanced technologies and supporting operations with expert maintenance and logistical services,” he says.
“Whether a mine or quarry needs equipment for a few weeks, several months, or an ongoing project, our rental approach ensures they get the right equipment without the financial burden of ownership, while also enjoying the flexibility to adapt to changing site conditions and project demands. This combination of cost savings, flexibility and expert support makes IPR’s rental model a perfect fit for quarrying, mining and industrial operations,” adds Van Rooyen.
Complementary support
Apart from offering a reliable and cost-effective product, IPR’s technical support and maintenance service plays a critical role in ensuring pump reliability and uptime, especially in remote or high-demand quarry and mine sites.
“IPR’s technical support and maintenance services are fundamental to ensuring that pumps and equipment remain reliable and operational, particularly in remote or high-demand quarry sites. By offering preventative maintenance, rapid on-site support, predictive monitoring and tailored solutions, IPR minimises downtime and maximises equipment uptime. This is critical for quarry operations that rely on continuous, efficient water management to ensure smooth and uninterrupted production,” concludes Van Rooyen.
