In recent years the development of sophisticated tunnelling techniques on major engineering projects has led to increased demand for accurate predictions of rates of dewatering required. In the extractive industry, planning constraints on lateral extensions for quarries has put increased pressure for deepening of existing sites below the water table. In both of these industries, the energy costs of dewatering have become significant operational factors, whilst environmental constraints are often critical to the feasibility of these schemes.
ESI has senior staff with very extensive experience of handling all aspects of this type of project. We are currently developing and operating groundwater models of some of the largest dewatering schemes in the UK. However our approach in all of these projects is to work closely with our clients to determine the most appropriate level of assessment required for each site. This ensures that we can achieve a cost effective solution in all cases.
