Active Dewatering Of Limestone Quarry And Drinking Water Production - Feasibility Assessment Using A Groundwater Model

Abstract : Lhoist Industries Ltd. plan to deepen the Boverie Quarry (Rochefort, Belgium), in which two Frasnian limestone reefs are exploited. If this project is allowed, the dewatering will dry up the Tridaine gallery that provides drinking water for the city and Saint-Remy's Abbey of Rochefort. Therefore, the project of deepening has to conciliate both quarry dewatering and drinking water production. The solution found by the quarry owner is to achieve the dewatering using three wells, for technical safety or water quality reasons, located in the periphery of the quarry and to distribute the pumped water to both the city and abbey. Hydrogeological characterization and a model using the SUFT3D research code tend to show that quarry dewatering and drinking water production could be achieved during and after the quarry operation, even by using a single well.
