Moving from decline to prosperity?
Peter Middleton
This year seems to have started with South Africa in a better place, with a stronger Rand, a high gold price and indications of a fragile economic recovery. Cyril Ramaphosa’s 2026 State of the Nation Address (SoNA) on 12 February left me feeling far more optimistic about South Africa’s future than I have for some time. Centred around moving South Africa from an "era of decline" to one of "prosperity and growth", he noted in his introduction that the world is rapidly changing; nar- row self-interest has replaced the common good; trade is used as an instrument of coercion; might is right, and the powerful impose themselves on the weak. To navigate this new world, said Ramaphosa, we must draw on our strength as a nation: “our values of dignity and equality, of non-racialism and non-sexism, diversity, and of the inherent worth of every person.” A unifying message for South Africans that, I believe, would have made Archbishop Desmond Tutu feel proud. Turning towards economic successes in 2025, he cited two consecutive primary budget surpluses; an improved credit rating; interest rates, inflation and na - tional debt coming down; the strengthened Rand; and the JSE performing “exceptionally well” – all reflecting a “broader economic recovery, investor confidence and increasing interest in South African equities”. Budget interventions announced included: a com- mitment of over R1-trillion to public infrastructure over the next three years; a reassurance that loadshedding had ended; a commitment to a more resilient energy system; and that, by 2030, “40% of the energy supply will come from renewable sources”. He also announced small-business support of over R3.5-billion and a 150% tax deduction for investments in new-energy vehicles. A key priority for 2026, he announced, will be to tackle the national water crisis. Ramaphosa identified dysfunctional municipalities as a key problem in this regard, with poor planning and maintenance as drivers of service delivery failures. The government has committed over R156-billion in public funding over the next three years for water and sanitation infrastructure, with work advancing on major projects, including the Lesotho Highlands Water Project (Phase 2), the Ntabelanga Dam (Mzimvubu Water Project), and the uMkhomazi Dam. A critical problem, he suggested, is that many metros, cities and towns use water revenue for other purposes, and very little is invested in upgrading and maintaining water infrastructure. “To address this challenge, in line with the commitment we made last year, we have intro- duced a new R54-billion incentive for metros to reform their water, sanitation and electricity services. This will
ensure that revenue from water usage is put straight back into fixing pipes, reservoirs and pumping stations. “Water outages are a symptom of a local government system that is not working,” he continued, before an- nouncing “a far-reaching overhaul” to address the root causes of dysfunction in many municipalities. The government is in the final stages of establishing the National Water Resource Infrastructure Agency to better manage and mobilise funding for infrastructure. The Water Services Amendment Bill will introduce a li- censing system for water service providers, allowing the government to revoke licenses for poor performance or failure to meet quality standards. In addressing broken water infrastructure, he said the government will work with municipalities to establish professional, ring-fenced utilities for water and electricity to ensure investment is directed toward maintenance. He also announced a local government overhaul with a view to creating a modern, fit-for-purpose system: “Arresting the decline of local government will require our collective action, which we are now taking. Learning from our experience over the past 30 years, we will, in the coming months, finalise a revised White Paper on Local Government. This will provide solutions for an effective local government system that will reimagine how local government works,” he said, adding that the current system is too complex and fragmented. “We will propose fundamental changes that recognise that some municipalities can assume more functions than others, and that we need a differentiated approach to municipal powers and responsibilities.” The funding model for municipalities will also be reviewed to ensure they have a sustainable revenue base for service delivery. At the same time, the govern- ment will expand support to municipalities that require technical assistance. “This must be the year that we make South Africa stronger,” Ramaphosa said in his conclusion: by fixing local government, fighting crime and corruption, creat - ing jobs, and building a state that works. “We must ensure that this rising tide lifts every South African. In this way, we can build a stronger, more resilient, and more equal society – one that stands tall among the nations of the world. We have indeed turned a corner. Now, we must look ahead and move with speed.” While positive spin is inherent to any presidential address, my key takeaway is that Ramaphosa is aware of the headwinds South Africa faces and is striving to put in place sensible, long-term solutions, “with unity and partnerships as the primary drivers for South Africa’s transition from recovery to long-term prosperity”.

Engen: Securing South Africa’s Energy Future Through Scale, Partnership and Purpose
As South Africa’s fuel industry convenes at the Fuel Industry Association of South Africa Imbizo in June 2026, the sector finds itself at a defining moment. Global energy markets remain volatile, supply chains are increasingly complex, and the pace of transition is accelerating. In this environment, scale, resilience and responsible stewardship are not optional; they are essential.
More recently, Engen has expanded its range through Café365 and Brazmata premium coffee, responding to demand for quality, speed and convenience. Café365 reflects a deliberate strategy to offer good quality, well-priced food and beverages across all LSM segments, ensuring that accessible, high-quality convenience is available to a broad spectrum of South Africans. “Being customer-led is not a slogan for us, it is a discipline,” says George Roberts, Engen CEO and Executive Vice President, South for Vivo Energy. “From Engen 1Stop to Quickshop, and from our Woolworths partnership to Café365, we have continu- ously reimagined the role of the forecourt. Today, our ambition is to make every Engen site the fourth stop in our custom-
South Africa’s first branded convenience retail format. The early 2000s marked another piv- otal shift with Engen’s pioneering part- nership with Woolworths. By integrating premium food retail into service stations, Engen fundamentally elevated customer expectations and reshaped the competi- tive landscape. This partnership remains a corner- stone of Engen’s retail strategy. Recently renewed for a further 10 years, it reflects continued confidence in the model and its relevance to evolving consumer prefer- ences. Looking ahead, Engen aims to dou- ble the contribution of the Woolworths Foodstop offering to its bottom line within the next five years, reinforcing its role as a key driver of growth and differentiation.
R ecent geopolitical tensions, particularly the conflict involv- ing the United States, Israel and Iran, have heightened volatility in global energy markets and exposed the fragility of concentrated supply routes. For South Africa, this underscores a critical reality. Energy security depends not only on access to supply but also on the ability to pivot dynamically in response to disrup- tions. Diversified supply chains are there- fore fundamental to ensuring continuity, stability and long-term resilience. Against this backdrop, Engen stands firmly positioned as South Africa’s leading fuel and convenience company. As part of Vivo Energy, Africa’s largest fuel retailer and distributor, and ultimately backed by Vitol, the world’s leading independent energy trader, Engen combines deep local expertise with global reach to secure sup- ply, enable industry and support national growth. Yet Engen’s market leadership has not been built on scale alone. It has been shaped over decades by a disciplined focus on customers and a legacy of innovation that has consistently redefined the fuel retail experience in South Africa. A Customer-Led Pioneer in Fuel and Convenience From the outset, Engen has anticipated and responded to evolving customer needs. In the 1980s, the introduction of 1Stop Service Stations transformed long-distance travel, offering 24-hour fuelling, safe rest facilities and quality food in an era when such infrastructure was limited. In the early 1990s, Quickshop redefined the forecourt by introducing George Roberts, Engen CEO and Executive Vice President, South for Vivo Energy.

value creation. “Transformation is integral to who we are,” Roberts emphasises. “It is about building a business that reflects South Africa and contributes to inclusive eco- nomic growth.” Through its corporate social invest- ment programmes, Engen continues to support education, skills development and community upliftment. The company’s enterprise and supplier development ini- tiatives strengthen local supply chains and create opportunities for small businesses.
safely, efficiently and reliably.”
Beyond Retail: Enabling South African Industry While Engen’s retail network of more than 1,000 service stations provides strong consumer visibility, its role extends far beyond the forecourt. Engen is a critical enabler of South African industry, supplying fuels, lubri- cants and specialised products across sectors including mining, agriculture, construction, marine and manufacturing. These sectors form the backbone of the economy, and their productivity depends on a reliable, high-quality energy supply. “Retail is what customers see, but be- hind the scenes, we are deeply embedded in the industries that drive South Africa’s GDP,” Roberts notes. “Our role is to ensure that these sectors can operate efficiently, safely and competitively.” In an environment of economic pres- sure and currency volatility, this reliability becomes even more critical. Engen’s inte- grated supply model provides the consis- tency and performance that businesses require to operate effectively. Safety at Scale With scale comes responsibility. Across its operations, Engen places safety at the centre of its operating model. Advanced technologies, including pre- dictive cruise control, electronic braking systems and AI-driven fatigue detection, support a layered approach to risk man- agement across its logistics fleet. Real- time monitoring of vehicle performance and driver behaviour enhances compli- ance and accountability. “Safety is non-negotiable,” says Roberts. “Operational excellence and safety leadership go hand in hand. We are committed to maintaining the high- est standards across every part of our business.” A Responsible Corporate Citizen Engen’s leadership in fuel and convenience is matched by its longstanding commit- ment to transformation and socio-eco- nomic development. Its Level 1 B-BBEE certification is underpinned by strong performance across key pillars, including leadership representation. Following integration into Vivo Energy, Engen South Africa remains 26% owned by historically disadvantaged persons, including a 21% shareholding by the Phembani Group and a 5% employee share ownership programme, which is expected to grow to 9% over time, further deepen- ing employee participation and shared
A Pan-African Champion with Global Reach
The completion of the transaction inte- grating Engen into Vivo Energy in mid- 2024 created a true pan-African energy champion. The enlarged group operates more than 4,000 service stations across 28 African markets, with recent expansion beyond the continent into Jordan. This scale provides access to diversified supply corridors, global trading capabilities and sophisticated risk management expertise. For South Africa, this integration is transformational. Through Vivo Energy and Vitol, Engen can leverage multiple sourcing options across global refining hubs, reducing dependence on any single region and strengthening the country’s ability to respond to market disruption. “Energy security is fundamental to eco- nomic stability,” says Roberts. “Our ability to draw on diversified supply sources and global trading expertise ensures that we can respond dynamically to market vola- tility and maintain reliable supply for our customers.” Engen’s transition from refining to a modern import-and-storage model fur- ther enhances this position. By sourcing refined products globally and efficiently distributing them through local infrastruc- ture, Engen improves flexibility, reduces environmental impact and strengthens resilience. Investing for Resilience and Growth Sustained investment remains central to Engen’s strategy. The company is currently investing approximately US$130 million (R2.2 billion) in supply infrastructure in South Africa, including the addition of around 250,000 m3 of storage capacity. This significantly enhances the country’s fuel import and distribution capability, reinforcing long-term energy security. At the logistics level, Engen continues to modernise its fleet, recently adding 30 Euro V fuel-specification trucks equipped with advanced driver assistance systems, AI-enabled monitoring and in-vehicle tracking technologies. These investments improve safety, reduce emissions and strengthen operational oversight. “Our investments are focused on build- ing a resilient, future-ready supply chain,” Roberts explains. “From storage infra- structure to logistics and digital systems, we are strengthening our ability to deliver
Driving a Progressive Energy Future
As the energy transition accelerates, Engen is evolving to meet changing de- mands. The importation of cleaner Euro V fuels supports improved emissions stan- dards, while investments in infrastructure and efficiency reduce environmental impact. At the group level, Vivo Energy is in- vesting in renewable energy solutions, including solar generation, supporting a balanced and pragmatic transition to a more sustainable energy future. “We recognise that the future of energy will be more diverse and more sustain- able,” adds Roberts. “Our responsibility is to ensure security of supply today while building the systems and capabilities re- quired for tomorrow.” Partnership as a Foundation for Progress Central to Engen’s approach is the strength of its partnerships. In South Africa, this includes collaborations with suppliers, government and communi- ties. Across the continent, through Vivo Energy, it extends to a broad network of stakeholders working together to build resilient energy ecosystems. “These partnerships enable invest- ment, support localisation and strengthen supply chains, ensuring that energy con- tinues to power economic growth across Africa,” concludes Roberts. As the industry gathers for the Fuels Industry Imbizo 2026, Engen’s message is clear. Scale matters. Partnership matters. Purpose matters. And in a rapidly chang- ing world, the ability to combine global strength with local relevance will define the future of energy. Rooted in South Africa, strengthened by a pan-African platform and backed by global expertise, Engen continues to secure supply, enable industry and enrich lives, building on a legacy of innovation that remains firmly focused on the future. https://www.engen.co.za/

Climate change a significant risk to African mining Climate change is no longer a distant threat; it’s a present-day disruptor reshaping industries, economies and ecosystems. In Africa, few sectors are as exposed or as vital as mining. WSP in Africa’s Kierra Chetty, Principal Consultant for Climate Change, and Nirvishee Juggath, Director of Water Management, highlight the risks and the need for a shift toward resilience-focused innovation and adaptive measures.
productivity. The Foundation’s World Risk Poll reveals that one in five workers world- wide, 18%, faced harm at work in the past two years, a numbewr that rises to 21% in the mining and quarrying sector. Workplace health and safety conditions are further compounded by operational challenges, especially in water-scarce countries like South Africa, where the ongoing water crisis adds another layer of complexity to mine sustainability and resilience. “One of the most significant and complex climate-driven challenges facing mining operations across Africa is the need to man- age water effectively. Water risk in mining is no longer just about scarcity; it’s about volatility. Sudden stormwater surges, pro- longed dry spells, and shifting water quality demands require adaptive systems that can capture, store, treat, and reuse water efficiently and safely,” says Chetty. During extended droughts, mines strug- gle to secure the water needed for core functions such as mineral processing, dust suppression and equipment cooling. This is especially problematic in arid regions where water scarcity is already a concern. “In a country as water-stressed as South Africa, long-term performance relies on circularity such as protecting catchments, designing for reuse, and treating water as a shared resource to sustain both operations and communities,” says Chetty. “Additional rainfall would not resolve mining’s water challenges. When high intensity or out-of- season storms do occur, they frequently overwhelm mine infrastructure, flooding pits, tunnels, haul routes and waste areas, disrupting operations and introducing sub- stantial safety hazards.” Managing excess water is a delicate balancing act: mines must determine not only how to remove it, but also where and how to discharge it without breaching en- vironmental regulations or causing down- stream harm. Failure to do so can result in contamination, legal consequences and reputational damage. Compounding these challenges is out- dated or insufficient infrastructure, often built in an era when climate volatility was

I ntensifying droughts, erratic rainfall, and rising temperatures are placing growing pressure on water availability and operational stability. For mining companies, the compounded risks of envi- ronmental volatility and resource scarcity demand urgent attention. “Climate variability has shifted from rare disruptions to an operating baseline, reshaping how the mining sector plans and protects its people. Weather extremes are no longer outliers but a reality that must be engineered into every decision to ensure operational stability and long-term value,” says Kierra Chetty, Principal Consultant, Climate Change, WSP in Africa. For many African countries, mining is not just a sector; it’s an economic backbone. In South Africa, for instance, mining contrib-
utes approximately 6% to the national Gross Domestic Product (GDP). Any disruption to operations, such as those triggered by the early onset of the Covid-19 pandemic and lockdown measures, can reverberate across the economy, affecting employment, exports, and fiscal revenue. Recovery from such shocks is often slow and complex, underscoring the sector’s critical role in economic resilience. Unlike sudden disruptions, the risks posed by climate change are largely predict- able, yet the risks are intensifying in both frequency and severity. The Lloyds Register Foundation’s Global Safety Evidence Centre reports that mine workers are increasingly on the front lines of this growing threat, facing extreme weather events and rising temperatures that compromise safety and
By integrating science-based insights, strengthening critical infrastructure, and optimising water and energy systems, mining operations can safeguard performance, protect communities, and reduce vulnerability while adapting effectively to an increasingly volatile climate.w

not a design consideration. Many mining facilities weren’t designed to withstand today’s extremes, let alone meet evolving regulatory standards. “This means that infrastructure was not designed for extreme events or even for the current design requirements being stipulated by global standards. Regulatory requirements have also improved over the decades, and design criteria for climate impact must be revised from original design requirements,” explains Nirvishee Juggath, the Director of Water Management at WSP in Africa. “Whether it is underground, open cast or open pit mining, the act of mining has an im- pact on water resources and water quality, while inflow from rain, runoff, recharge and lateral groundwater ingress is inevitable,” adds Juggath. To stay resilient, mining companies must strike a careful balance, adopting innovations in production and methodolo- gies to improve water efficiency while also developing strategies to capture and store excess water during the wet season for use in the dry season. “During high rainfall events, water availability is not an aspect of concern for communities and industries, but during the dry season, that’s when water quantity
and quality become an issue,” says Juggath. “Irresponsible use and management of wa- ter do not help the situation.” In many African countries, the relatively low cost of water – particularly in regions where pricing models fail to account for scarcity or environmental stress – can diminish the financial incentive for mining companies to invest in robust water man- agement practices. Juggath notes that while water steward- ship has often been deprioritised in favour of more immediate profitability, this is changing. “As mines are at the forefront of the risks climate change poses, with the inevitable impact on infrastructure and productivity, industries want to better understand how good water management can prevent loss, and mitigation measures they can take.” Juggath encourages mining companies to reassess their risk profiles, operational plans and environmental commitments. This includes reviewing infrastructure against best-practice design standards and con- ducting design reviews, reliability assess- ments and risk analyses. “Mining companies should develop a risk-based action plan that identifies vulnerabilities and prioritises upgrades, particularly for critical systems and facilities.”
“We are seeing a clear shift across the sector toward resilience-focused innova- tion and adaptive measures, where renew- able and hybrid power systems, advanced process optimisation, real-time monitoring, and closed-loop water solutions are being integrated to reduce dependence on vulner- able resources, strengthen operational con- tinuity, and enhance overall efficiency under increasing climate pressures,” says Chetty. Infrastructure upgrades are also gain- ing momentum, with emphasis on building resilience into tailings storage facilities, haul roads and processing plants. “The frequency and severity of climate- related extremes are increasing, but so is our capacity to engineer resilience. By integrat- ing science-based insights, strengthening critical infrastructure, and optimising water and energy systems, mining operations can safeguard performance, protect communi- ties, and reduce vulnerability while adapting effectively in an increasingly volatile climate landscape,” concludes Chetty.

Dewatering trends shaping pump choices in Africa
Dewatering on African mines is being reshaped by deeper underground workings, unpredictable rainfall and rising energy costs, influencing whether diesel-driven or submersible pump solutions are most suitable. Integrated Pump Technology’s Jordan Marsh explains.
A s African mines go deeper and rainfall patterns grow increasingly unpredictable, dewatering has moved beyond being a support function to become a strategic discipline. The choice between diesel-driven and electric submersible pumps is now influenced by evolving risk profiles, both underground and on the surface, as well as considerations of energy efficiency, maintenance and mobility. On surface mines, the challenge is ampli- fied by heavier storm bursts and the need to keep haul roads and pit floors stable. Short, intense downpours can cause sudden pit- lake rises and flooding that demand rapid response. In these situations, high-throughput diesel-driven pumps mounted on trailers or skids are often favoured, as they can be moved quickly to different locations without relying on fixed electrical infrastructure. The ability of auto-priming diesel pumps to handle fluc - tuating inflows without priming delays makes them indispensable for these unpredictable surface applications. Mobility is a further consideration. Production teams require equipment that can follow the work, particularly in operations where water inflow points shift as pits expand. Diesel-driven solutions with built-in fuel tanks and controls reduce setup time and enable small teams to respond effectively. Pontoon- mounted units also provide reliable suction conditions despite fluctuating water levels, reducing the risk of cavitation and protecting pump performance. With surface water often carrying abrasive silt and fines, durability is critical, making pumps with robust wear-re- sistant components an important investment. Underground mines, however, face a different set of challenges. Longer declines, wetter stopes and tighter control over elec- tricity usage are driving demand for efficient submersible pumps that can operate continu- ously and reliably. Rising energy costs mean that submersibles sized precisely to their duty offer significant advantages, especially when coupled with automated level controls and start/stop systems to reduce unnecessary run hours. The compact design of submersibles also makes them well-suited to confined underground environments, eliminating the need for suction lines and reducing potential

trip hazards. In many cases, underground water is not only abundant but also dirty or chemically ag- gressive. Pumps must therefore be equipped with seals, cooling systems, and materials that can withstand abrasive fines and corrosive conditions without frequent maintenance. Built-in motor protection, leakage sensors and durable cabling extend operational life and reduce downtime. Choosing between diesel-driven and sub- mersible pumps ultimately comes down to the application. Diesel-driven auto-priming pumps are ideal for emergency bypasses, stormwater management and pit-lake dewa- tering where mobility and independence from the grid are crucial. Submersibles, by contrast, excel at routine, continuous underground op- erations or fixed surface installations where reliable electrical power is available. The total cost of ownership further influ - ences the decision. While diesel pumps bring fuel and engine servicing costs, they elimi- nate the need for electrical infrastructure. Submersibles, meanwhile, generally offer lower energy costs and fewer moving parts but require correct protection systems and monitoring to achieve maximum lifespan. Jordan Marsh, Managing Director of Integrated Pump Technology, stresses the importance of not treating dewatering as an afterthought. “The best dewatering outcomes come from pairing proven technology with a
clear understanding of each mine’s hydraulic realities,” he explains. “That is why we supply world-class brands with long African track records – Grindex for electric submersibles and Godwin for diesel-driven auto-priming units – and the local application know-how to specify them correctly for reliable long-term performance supported by localised support across the region.” Specification errors can be costly. An un - dersized pump may result in flooding and lost production, while an oversized pump wastes energy and accelerates wear. Mines also operate in remote locations where logistical challenges make access to spares and techni- cal support critical. Marsh highlights this as another reason why the supplier relationship is so important: “Mines need pumps that start every time, run to duty and keep running. Grindex submers- ible pumps and Godwin diesel-driven units have earned their reputations in Africa for exactly that, reliability in tough conditions. Our job is to combine these technologies with rapid support, correctly specified accessories and a spares pipeline that keeps risk low and output high.” Integrated Pump Technology’s approach focuses on ensuring mines receive not only the right pump but the complete solution. This includes correctly matched accessories such as pipework, valves and strainers as well as service models that balance cost and

The central role of pumping equipment manufacturers
Following Water Week from 16-20 March, Hugo du Plessis of KSB Pumps and Valves highlights the importance of our water infrastructure and the significant role manufacturers can play if included in the full circle of developing, engineering, operating and maintaining it. E quipment manufacturers in the water industry should play a cen- tral role in developing solutions to the country’s growing potable and ering a reliable water supply a daily challenge for municipalities and water utilities. Ensuring that water reaches households, businesses and even livestock requires technical expertise and partnerships with original equipment manufac- turers (OEMs).
that pumps operate efficiently and safely over the expected decades-long operation of such systems. It also provides training and educa- tional presentations to the next generation of engineers, helping them understand the full water cycle from river to tap and back to treat- ment so that they can manage infrastructure sustainably. “We engage directly with water boards and consultants to offer solutions that will last 20-30 years, where we assist with planning and execut- ing systems that can withstand daily demand and ever-growing communities,” he concludes. https://www.ksb.com/en-za/
wastewater challenges. Hugo du Plessis, market area manager for KSB Pumps and Valves, says manufacturers of pumps, valves and related equipment are most important when systems are being designed or upgraded, as they know their products’ capabili- ties better than anyone else. Therefore, manu- facturers should be included at every stage of a project to ensure that the work is carried out within the equipment’s capabilities. Furthermore, global companies like KSB have a wealth of institutional knowledge and technical expertise that they can lend to consult- ing engineers, municipalities and waterboards to determine the best solutions for a region’s challenges. “In South Africa, our water boards manage decades-old infrastructure. Their challenges include leaks and the maintenance of equip- ment such as pumps and valves. During Water Week from 16-20 March, we decided to make our services available to help water boards run more efficiently and to identify how best to ad - dress issues such as skills shortages and staff training,” says Du Plessis. It is clear, he continues, that our water delivery infrastructure needs an overhaul, with ageing pump stations, rising demand, and water treatment costs that cannot be billed due to leaks or other losses. This makes deliv-
“Our operations combine local manufactur- ing with global engineering knowledge, and our engineers can support municipalities directly, evaluating systems and optimising pump perfor- mance for bulk water transfer, treatment works and reticulation networks. Working closely with OEMs also ensures local authorities have rapid service response and on-the-ground technical support once projects have been completed. “The pump stations operate 24/7 under heavy demand. Having trained engineers who under- stand the full system helps utilities maintain supply,” Du Plessis adds. He explains that KSB is currently helping many of the country’s utilities and municipalities to map and measure water supply, assess pump performance and plan remedial action where necessary to ensure systems are operating at full capacity. Advanced tools, including smart meters and data-driven pump monitoring for system optimisation and preventative main- tenance, are also being used to enable water boards to identify problem areas and adjust operations before minor issues escalate into major failures. KSB staff are currently working with several progressive municipalities on maintenance pro- grammes and refurbishment projects to ensure
