5.5kW Solar-Powered Borehole Water Pumping System Installed for Todal Mine
Solar-Powered Borehole Water Pumping System Installed for Todal Mine by Gi Glo
As part of our commitment to delivering sustainable and cost-effective utility solutions, the Gi Glo team designed and installed a robust 5.5kW solar-powered borehole water pumping system at Todal Mine. This system was specifically engineered to address the mine’s ongoing water supply challenges and to provide a long-term, off-grid solution capable of supporting its full water demand.
The system draws water from an 80-meter-deep borehole, delivering it to a 30,000-litre storage reservoir situated 2.5 kilometers away from the borehole site. Due to the extended distance and the elevation dynamics involved, the water system required careful hydraulic and electrical planning to ensure maximum efficiency and durability, with minimal maintenance required.
At the core of the system is a 5.5kW AC borehole pump, capable of handling the required flow rate and head pressure. The pump is controlled by a 5.5kW Variable Speed Drive (VSD), which plays a vital role in regulating the motor speed based on real-time demand. This smart control function not only optimizes power usage but also reduces mechanical stress on the pump, prolonging the system’s lifespan and improving overall energy efficiency.
Power for the pumping system is provided by a solar array consisting of 12 × 550W photovoltaic panels, strategically mounted to maximize sun exposure throughout the day. The solar panels convert sunlight into clean, renewable energy, ensuring the entire water pumping process operates independently of the national grid, thus eliminating the risk of water shortages due to load shedding or grid instability.
One of the key features of the installation is the integration of a borehole telemetry system, which brings intelligence and automation to the water management process. This system enables real-time monitoring of both borehole water levels and reservoir water levels. It ensures that the pump switches on and off automatically based on preset thresholds such as the reservoir reaching capacity or the borehole requiring recovery time, thereby preventing over-extraction and protecting the pump from running dry.
All associated piping, cabling, and electrical protections were professionally installed using high-quality, durable materials to withstand both the physical demands of the mining environment and potential environmental threats. This includes surge protection, secure cable routing, and theft deterrent measures to maintain long-term system integrity.
With this installation, Todal Mine now benefits from a reliable, autonomous, and environmentally friendly water supply solution that meets operational needs without depending on the local water authority or unstable grid power. The system supports the mine’s broader sustainability goals while simultaneously reducing utility costs and enhancing operational resilience.
This project is a testament to Gi Glo’s technical expertise and our commitment to delivering tailored energy and water solutions that provide long-term value, efficiency, and environmental stewardship
