ICMM water risk study: key implications for mine design and tailings teams

30 Second Briefing
Nearly two-thirds of global mining and metals facilities are sited in areas of significant physical water risk, according to ICMM’s new Global Mining and Metals Water Dataset. The analysis also finds that competition for water between mine sites and other industrial and domestic users is the dominant physical risk driver, rather than solely hydrological scarcity. For geotechnical and processing teams, this points to tighter constraints on dewatering, tailings water balances and make-up water allocations, with permitting and community relations becoming critical design inputs.
Technical Brief
- ICMM’s Global Mining and Metals Water Dataset aggregates facility-level exposure to physical water risk globally.
- Dataset links each mine or plant to basin-scale hydrological and competing-use indicators for comparative assessment.
- Facility siting relative to municipal and industrial abstractions is explicitly mapped, informing local permitting constraints.
- Output can be overlaid with tailings storage locations, clarifying where water risk intersects with TSF safety obligations.
- ICMM frames water risk as a material safety and operational continuity issue, not only a sustainability metric.
- Findings imply stricter operational controls on process-water recycling, seepage recovery and contact-water segregation.
- For similar projects, early integration of basin-level water allocation data into mine design becomes a de facto safety control.
Our Take
ICMM’s earlier Global Mining & Metals Greenhouse Gas Emissions Dataset (March 2026) shows the council is already quantifying climate exposure; adding quantified water risk to that toolkit will make it harder for member companies to ignore site-level trade-offs between decarbonisation projects and local water constraints.
