FAST tracked through a collaborative client / contractor approach to guarantee that construction of the pipeline infrastructure occurred prior to the 2020 wet season to meet the required output capacity of 25-30Ml per day. The pipeline construction could not interfere with the operation of the exisiting pipeline which presented a challenge due its location and proximity to be 1,000mm from centre to centre within the easement. The new pipeline was also constructed in a restricted working width across the lake. The Development Application easement width of 6,000mm was static and could not be breached under any circumstances.

Evolution’s Cowal Operation is located approximately 40km north-east of West Wyalong in New South Wales, Australia. This high-quality Australian gold asset with a long history of stable, large scale, low cost production. The mine pit encroaches the Lake Cowal ephemeral lake system. The lake is approximately 9.5km wide when full.
