Technosub was mandated to dewater a pit from a client in Quebec. We provided two complete pumping stations and a power station of 40 feet each, in which five Grundfos 1100S2500-6 submersible 250HP pumps and three 600HP Technojet MH200-250 / 3 pumps are installed. After only 3 days of operation, the system had to be stopped because there was no more water in the pit!
Design and creation of a water treatment system to be installed in a tunnel under construction. With a capacity of 450 GPM, this system eliminates sedimentation in the dewatering piping, eliminates the discharge line cleaning process, and facilitates water treatment at the final treatment plant.
Design, complete kit preparation and installation of two Technojets pumps underground. Pumps have been tested and delivered to mine site. Final underground installation of the two Technojet pumps connected to the mine sump.
Dewatering a mine with 21 pumps, including control pannels, discharge piping and valves with flowmeters. This major project calculates a total of 31 000 USGPM and 500ft TDH (Total discharge head).
