Dewatering

Effective dewatering for dry excavations

We define dewatering as all the technical equipment required to keep construction pits free of water. For this task, we either use the so-called wellpoint method or drill wells with a diameter of 300 to 1500 mm.

Implementation

The design of the dewatering system is followed by the construction of the wells. A fully automatic control system including a monitoring system is implemented at the monitoring level. The warning system enables various alarm messages such as power failures or exceeded water levels. Specially trained personnel can react immediately via remote enquiry.

Applications

Wells for both drinking water supply and temporary dewatering
Well construction using filter or solid pipes and, depending on requirements, in untreated or galvanised steel, stainless steel, PVC or PE
Dewatering in the wells using the gravity or vacuum method
