Deep Wells

Based on the site specific subsurface conditions , deep wells are often the most efficient and cost effective dewatering solution. In the case of glacial and alluvial deposits of coarse-grained sands, gravels, cobbles, and boulders, deep wells are often the…

Vacuum Wellpoints

Vacuum wellpoints are well suited for a wide range of soil permeability’s (fine to coarse grained soils). They are generally 15 to 25 feet deep and constrained by the limits of the vacuum to pull water out of the ground.…

Eductor Wells

Eductor systems are most advantageous when dewatering deep excavations where the volume of water to be pumped is relatively small because of the low permeability of the aquifer. Like vacuum wellpoints, eductor wells are spaced 2 to 10 feet on…

Artesian and Difficult Conditions

In some areas, the existing groundwater is under pressure. If this pressure is sufficient to cause the groundwater to flow above the ground surface , this is known as an “Artesian” groundwater condition, and can pose significant challenges when constructing…

Water Treatment

Water treatment is often required to remove solids, volatile organics and other undesirable compounds before groundwater generated from dewatering operations can be properly discharged.
