Pump Transfer Station – Mardie Salt and Potash

We were engaged to deliver the detailed design of the pump transfer stations at the Mardie Salt and Potash Project. We have supported BCI Minerals Limited in its development of the Mardie Salt and Potash Project, a sustainable opportunity to develop a large-scale, multi-generational solar evaporation operation on the Pilbara coast of Western Australia. The facility utilises nine evaporation ponds across the site, due to topographical constraints, gravity feed of the brine was not possible across all the seawater evaporation ponds. Agilitus was engaged to deliver the detailed design of the pump transfer stations. Pump Station 2-3 consisted of three 250 kW pumps with a combined capacity of 25,000 m3 per hour feeding three DN1200 pipelines between Pond 2 and 3. Pump Station 3-4 included two 250 kW pumps capable of supplying 20,000 m3 per hour to two 300 m long buried DN1200 pipelines crossing underneath a flood plain. The high saline environment was a challenge for material selection. Co-extruded High-Density Polyethylene (HDPE) was selected for the pipeline to maximise value as it is not susceptible to degradation by seawater brines, has a high UV degradation resistance and ease of installation / maintenance.
