Below grade structures often extend below the local groundwater table. We often encounter the need to temporarily dewater excavations in conjunction with the construction of shoring walls. Typically the dewatering system operates until the permanent drainage system of the structure can be put online.

Our dewatering systems are geared for large drawdown requirements (i.e. 10 feet or greater). The dewatering wells are drilled down into the upper layer of bedrock and a submersible pump is placed inside the well. The groundwater is then pumped from the bottom of the well and either discharged or, if contaminated, treated before discharge.
