Raw water is natural, untreated water drawn from local weirs and rivers. Reducing the use of and reliance on this valuable resource is a key objective for Curragh, with the team’s innovative approach continuing to deliver outstanding results.
Since raw water saving initiatives were introduced in 2014, Curragh has cut back consumption by almost one-third. This means the team is exceeding its target of a five per cent annual reduction, and has achieved a further 8 per cent reduction this financial year from the FY 16 raw water usage thanks to the implementation of a range of new ideas.
In 2016, infrastructure was installed to connect harvested water to Curragh’s industrial water system. Flows were initially lower than expected, but a change of filter type fixed the issue and delivered a positive water-savings impact. Curragh now has the capacity to blend more harvested water with less raw water for industrial applications, therefore reducing the mine’s reliance on raw water as the primary source.
