Pumping off the storm water arising on the roofs during the construction phase.
Eight type KTVE21.5 pumps with integrated electrode controls were installed in the shafts. The slim electrodes, which are attached, replace float sensors which take a lot of space and are maintenance-intensive. Only the motor line of the pump has to be relaid; no additional cables for float switches have to be connected.
