Trailer pumping station for underground use in case of emergency. The system was designed to pump water from a spill using a diaphragm pump into a tank on the trailer. From there, the water is pumped to the surface of the mine for disposal. The main challenge of this project is the calcium content in the water to be pumped, which justified the use of special stainless steel construction pumps.
