WestLand designed upgrades for three existing Pregnant Leach Solution pumping stations and associated pipeline. The design includes two pumping stations, a floating barge pump, and approximately 3 miles of HDPE pipeline. Project tasks included detailed hydraulic design, low voltage electrical and VFD design, process and instrumentation diagrams, medium-voltage switchgear design, structural and geotechnical design, surge analysis, detailed cost estimates, detailed construction specifications, hydraulic flow diagrams, a detailed HAZOPs analysis and report, and a hydraulic analysis of the existing pump system. Due to the highly corrosive nature of the pumped fluid, significant amounts of detailed engineering and vendor coordination were required to prevent corrosion and to minimize costs.
