Abstract: This paper presents the dewatering design results for a deep excavation of an industrial facility. The proposed dewatering is a well point system. The required flow from the well point is estimated by using Dupuit Formula. The number of well points and their locations are carefully designed. The decrease in groundwater level and its required pumping duration are also predicted.

Key words: Excavation Dewatering, Dupuit Formula, Dewatering Depth, Well Points
