Client Overview
Critical Infrastructure at Scale
Gold Fields manages a large tailings storage facility covering more than 400 hectares, containing hundreds of millions of tonnes of material.
Monitoring water levels across the dam is a critical safety, compliance and operational requirement.

Live Monitoring
The Challenge
Monthly Manual Checks Left Critical Gaps
Historically, water levels were checked manually using physical instruments distributed across the site. Completing one full monitoring cycle took almost a month, meaning engineers only saw conditions after the fact.
Sudden changes in water levels or emerging risk conditions could go unnoticed for weeks, making it difficult to respond quickly or maintain a continuous picture of the dam's health.
The process was labour intensive, slow and increasingly misaligned with modern tailings management expectations.
Why Tailings Intelligence Matters
The Greatest Risk Builds Slowly and Silently
Tailings dam failures are catastrophic, but the greatest risk often builds slowly and silently. Internal pressure, seepage and water imbalance develop over time, long before visible failure occurs.
When early signals are missed, the consequences are severe:
Environmental Fines
Up to R10 million under NEMA
Regulatory Penalties
Up to R2 million per day, where applicable
Cleanup Costs
Exceeding R1 million for minor incidents
Production Losses
Often outweigh regulatory penalties
Reputational Damage
Loss of social licence to operate
Insurance Impact
Increased premiums or refusal of cover
These outcomes are largely avoidable when early warning signals are detected and acted on in time.
The HYDRA Solution
Real-Time Monitoring Layer with Smart Vision
Working with Smart Vision, HYDRA was deployed as a real-time monitoring layer for the Gold Fields tailings facility.
1
Smart Sensor Deployment
Smart water-level sensors were installed at critical points across the dam, automatically capturing readings and transmitting data continuously.
2
Live Dashboard Integration
All measurements now flow into a live HYDRA dashboard, providing instant visibility into water levels, trends and potential risk conditions.
3
Automated Alerting
The system automatically generates alerts when predefined warning or trigger thresholds are reached, ensuring engineers are notified immediately when conditions change.
Impact
From Retrospective Reporting to Live Safety Intelligence
Instant visibility of water levels, replacing weeks-long manual reporting cycles
Ability to act immediately when levels rise or conditions change
More than 90 percent reduction in monitoring time
Improved safety oversight and confidence in dam condition
Stronger alignment with international tailings management and safety standards
HYDRA transformed tailings water monitoring from a retrospective, manual process into a live safety intelligence capability.
Why This Matters
For Mining Operators
For tailings facilities of this scale, delayed information introduces risk. Real-time visibility enables faster decisions, clearer accountability and safer operations.
By digitising water-level monitoring, mining operators gain continuous insight into one of the most critical indicators of tailings dam performance, without increasing site workload or operational complexity.
Continuous Safety Intelligence
Real-time visibility into critical tailings dam indicators without increasing operational complexity
