Bowman directed a $2M program to design and construct a series of liner systems in the Bushkill Stream which borders Hercules Cement’s Stockertown Quarry. Water from the stream historically leaked into the quarry through karstic features with required expensive dewatering efforts. The project included the design and layout of a 130M gallon per day (MGD) stream bypass, so that the liner system could be installed during dry conditions. To date, the quarry has seen a 15 MGD reduction in infiltration.
