Lowering and maintaining the groundwater table. At the beginning several medium-sized pumps were employed which burdened the mains electricity supply excessively. As the river Rhine flows past at a distance of 200m the groundwater could only be lowered with difficulty.
A pump of type KRS2-89 incl. hosepipe and 300m drainage in the form of a pipe. Draining of the excavation for the whole construction period. Operation of the pump in 24-hour pumping on snore mode.
