$60K"DWS designed and ran the dewatering across our whole dive structure. System never missed a beat and their crew responded fast every time we changed the program."
"Great local knowledge of the ground conditions. They had well points in and the trench dry days quicker than we expected. Would use again on any wet dig."
"High water table right on the river and DWS kept the basement bone dry from start to finish. Handled all the discharge compliance too. Highly recommend."
