KEY SUCCESS
UON were tasked with delivering a dewatering solution for an old mine being reactivated, via an existing ventilation shaft. This required a custom shaft cap to be designed and fabricated to facilitate two 147 kW submersible pumps, installed to a depth of 300 m. Additional telemetry was provided to monitor multiple level sensing probes and to enable full remote access control.
