Mining operations are among the most water-intensive industries, and that dependence is becoming more expensive and risky. According to the International Council on Mining and Metals (ICMM), nearly two-thirds of mines face high water-related risks, from aquifer depletion to spiralling costs and tighter compliance.
Mines can’t operate without water. The shift happening now is how they manage it – moving from seeing water simply as something to be pumped and discharged, to treating it as a strategic resource to be reused, recycled and controlled.
“Mines are starting to understand that water security is operational security,” says Chetan Mistry, Strategy and Marketing Manager – WSS (Africa, Middle East, Turkey, India) at Xylem. “The progress comes when you combine a clear water strategy with the right technology and a flexible investment model. That intersection is where compliance, conservation and cost control meet.”
For rental companies, that shift creates a major opportunity. Instead of a one-off dewatering job, mines now need long-term water management partnerships. The model is built on three pillars:
1. Water Stewardship as a Starting Point
Water is a shared resource, and stewardship is the foundation for managing it responsibly.
UN data shows only 38% of industrial wastewater is reported as treated, and just 27% as safely treated. For mining, improving stewardship means more than compliance – it means tracking water quality across the entire cycle, aligning with frameworks like the Minerals Council’s best-practice guidelines, engaging with communities and regulators, and building water risks like scarcity, flooding and regulatory changes into enterprise risk planning.
Rental providers are enabling this by offering monitored rental fleets – from water quality monitoring systems to temporary treatment packages – allowing mines to scale stewardship without heavy upfront CAPEX.
2. Water Reuse and Closed-Loop.
Thinking this is where water truly becomes a resource. Instead of using fresh water for every task, leading mines are adopting a reuse hierarchy: reserve high-quality water for sensitive processes, and deploy treated water for dust suppression, cooling, washdown, and stockpile management.
The business case is clear. Pan African Resources, for example, cut total water consumption by 10.9% and reduced its reliance on municipal water by 45.6% through increased recycling and closed-loop systems.
For many operations, renting the reuse solution is more viable than buying it. Temporary water treatment plants, mobile filtration units, reverse osmosis systems and rental booster pump sets allow mines to test, scale and adapt reuse strategies for specific pits, seasons or closure plans – without locking capital into permanent infrastructure.
3. Energy-Efficient Treatment
Cost remains the biggest barrier to better water management. But two realities are changing the calculation: water costs are rising fast, and treatment technology has become far more energy-efficient. With 65.7% of mining and metals facilities located in high water-stress areas and 27% exposed to high drought risk, according to the ICMM, the risk of doing nothing now outweighs the investment.
Modern rental fleets are addressing this with variable-speed drive pumps, high-efficiency aeration systems, and smart, IoT-enabled monitoring. These systems optimize energy-intensive tasks like pumping and aeration, give real-time data on consumption and bottlenecks, and support predictive maintenance – reducing both power bills and unplanned downtime.
The Rental Advantage: Flexibility Over Ownership
Ultimately, turning water from a liability into leverage requires adaptable thinking. A mine evaluates ore grade and plans its drilling program meticulously – water deserves the same strategic approach.
This is where the rental model fits perfectly. It allows mines to access the latest water technologies, manage seasonal inflows, meet discharge compliance, and trial water reuse loops without a permanent capital commitment.
