About Overwatch

Real-time subsurface monitoring technology for tailings storage facilities

Overwatch combines patent-pending subsurface probe technology with an internet of things (IoT) network to directly measure change and monitor TSF’s health from below the ground. Using 6 cutting edge sensors to directly monitor 9 measures known to be contributors to TSF failure, Overwatch enables TSF health to be proactively monitored to determine risk of failure with enough time to prevent loss of life, catastrophic environmental damage or prevent a stop to commercial operations.

Supporting adherence to the updated GISTM and ICMM requirements.

Our innovative solution utilises an interdisciplinary knowledge base across geophysics and network engineering to minimize and manage risk across a TSF life cycle and enable clear systems and levels of review.

World-first probe technology

Measure the deep dark subsurface, directly.

Developed in conjunction with world-leading experts, Overwatch’s ruggedised subsurface probes are tactically installed within key identified locations of a TSF. Enclosing multiple self-powered sensors, Overwatch then provides direct measurement of geological, geophysical and hydrogeological changes in real-time and transmits the data to our secure digital interface.

Visualise asset health with a powerful digital twin solution

Most existing monitoring solutions have remained static for the last decade. However, it’s become increasingly clear that these slow and resource-intensive processes don’t align with the accuracy and immediacy required for modern infrastructure monitoring. Overwatch was developed to accelerate the status-quo forward. 

Reliable, real-time insights are brought to life on Overwatch’s cutting-edge online and mobile platform to keep tailings storage facilities safe, sustainable and cost-efficient. Plus, integrate any existing monitoring solutions with Overwatch to realise the best of both worlds. 

Overwatch’s innovative digital twin technology features steadfast cyber security and data encryption measures. This ensures that data is accessible only to the right people at the right time - safely and at speed.

Dashboard

Monitor the unmonitored today for an informed tomorrow 

From initial consultations, through to probe installation and client onboarding, expect expert support for the entire life-of-mine. This guarantees Overwatch’s enduring viability, scalability and reliability.

.01 Consultation

To develop a thorough understanding of a client’s subsurface and ensure a value-based installation of our probe, Hermes and Soteria’s expert subsurface consultants carry out onsite geophysical subsurface analysis of the TSF.  A bespoke report is produced to highlight areas of importance to the client and inform key locations for installation.

.02 Installation

Overwatch’s next-generation ruggedised probes enclosing our powerful sensors are carefully installed in the key subsurface locations via a standard geotechnical or sonic drilling rig and 200mm diameter hole to the identified depth of risk.The hole is backfilled and reliable surface network infrastructure is established to enable self-powered real-time data transmission.

.03 Test and train

Following installation, the Overwatch online platform is configured to establish key thresholds of pore pressure, seismic activity, pH, salinity, temperature, and moisture. Working with the site’s requests, we customise role-based access to data and configure the platform’s notification and action features to automate intervention where necessary.

.04 Ongoing support

As a genuine life-of-mine monitoring solution, the reliability of Overwatch’s devices and platform are secured by around-the-clock support from Hermes and Soteria. A 24/7 helpline ensures assistance is only ever a call away.
