Itasca is experienced in estimating the dewatering needs of a construction site or mine to temporarily lower groundwater levels below the natural groundwater level, in all seasons, to provide for safe excavation construction and working environment during operations. Itasca also predicts dewatering rates, performing numerical modeling to estimate dewatering and to design and optimize the dewatering and water-disposal systems, drain holes, and monitoring wells for tunnels, caverns, foundations, and construction sites.
