The Client's Needs

Ballarat Goldfields wanted to implement a safe and consistent method of dewatering the underground mine to continue to meet environmental constraint limits. 

They wanted to ensure that their mine water was treated to protect the surrounding environment and local waterways whilst providing an option for reusing this water

§Salt needed to be removed from this water, and by installing a water treatment plant to remove this salt ensured that the site met safe discharge requirements for the mine’s dewatering process

§Ballarat Goldfields is focused on continually improving their environmental performance by reducing their potable water consumption and rehabilitating the environment affected by their activities

Veolia's Solution

Veolia Water Technologies Australia was awarded the contract for the design & build of a water treatment plant for the Ballarat mine site. 

This plant treats pre-treated mine water from the gold mine using chemical oxidation, greensand filtration and reverse osmosis before being discharged to the siltation pond and then the river following the wetlands. 

The high quality treated water ensures compliance with strict environmental discharge limits and increases environmental flows allowing the mine to operate and discharge during drier seasons. 

Veolia also provides Hydrex® water chemicals and after-sales technical support for process operation and troubleshooting advicefor operators on site.
