Klohn Crippen Berger designed a large wastewater pump station to pump Process Affected Water (PAW) to a pond which collects groundwater seepage and surface run-off water from an External Tailings Facility (ETF) at the client’s oil sands mine.
The pump station was designed for staged construction to handle the increasing operating head and flow requirement associated with the progressive dyke raises which results in both a higher pump discharge elevations and larger catchment areas. With four installed pumps originally (one is a standby unit), the pump station initially provided a design flow of 920 l/s at heads of up to 25 m. Later, the total output was doubled to 1840 l/s at heads of up to 50 m with the addition of four pumps and a second force main. The increasing head requirement was taken into consideration with the provision for progressive impeller changes on the existing pumps.
KCB provided multidiciplinary engineering services which included Mechanical, Electrical, Instrumentation and Control, Civil and Geotechnical Design. KCB services spanned all project phases; from scoping study through feasibility to detailed design, then KCB provided technical support during construction including preparation of all construction drawings and equipment specifications.
