Our team on the Kidston Pumped Storage Hydro Project in outback Queensland has used 100% non-potable for construction purposes to date. The Kidston project involves the world first conversion of a disused gold mine into a pumped storage hydroelectric plant.
Water for construction use has been sourced from the Copperfield Dam and associated pipeline, which was constructed to supply the mine with water when operational. Water has also been used from one of the large pits on site, which has subsequently filled with rain water since the mine closure 20 years ago.
Over 25 megalitres has been sourced from the onsite pit (equivalent to 10 Olympic sized swimming pools), with the remainder coming from Copperfield Dam.
The water is used for various purposes on site such as dust suppression, concrete batching, conditioning, and also as an input to the onsite water treatment plant, which produces the site's drinking water.
