Tsurumi was contacted by SUEZ company to support with the decontamination of the soils of the former FORD site in Bordeaax, where they manufactured gearboxes for trucks and cars. The grounds were heavily polluted with oil and hydrocarbons that mixed with water and sand. Furthermore, there were limitations to the piping available, hence pumps had to be selected carefully. However, the biggest challenge was that every cleaning cycle, once started, had to finish as a malfunction would cause additional work.

New shafts were being excavated for the expansion of the underground mine in Serbia. Contractors in charge of the project used submersible pumps of other brands but had very bad experiences with too short lifespan of the pumps due to the heavy abrasive medium that has been pumped.

Grand Paris Express is one of Europe's most expensive tunneling projects in progress.

At the new Le Vert de Maisons Station, a high-head delivery system is required to effectively handle the dewatering process throughout the tunnel's construction phase.

In a big powerplant project in Chile, 70km of tunnels were being drilled around the Andes. By design the tunnelling was separated into main tunnels and smaller supply tunnels. One of the latter ones was built with a total length of more than 8km for the purpose of providing access to the main tunnelling area. During the construction of this supply tunnel plenty of water had to be removed over a long distance.

In a quarry in Germany the operator was mining for basalt using dynamite to extract the basalt from the surrounding grounds. This method in terms of mining is very efficient as you can harvest big amounts of basalt quickly. The challenge of this application is the groundwater inside of the excavation pit which needs to be removed constantly in order to collect the material. However, the groundwater contains plenty of abrasive substances resulting from the dynamite explosions including sharp, crushed rock.
