Mining consumes large volumes of water in the extraction and processing of minerals however it also has an established tradition of utilising onsite water sources obtained from dewatering and site runoff where possible. Most water uses on mine sites require large scale sources of supply.

High water uses suitable for alternative water supply in mining include:

 Plant and vehicle wash;

Transport of ore and waste;

Separation of minerals;

Cooling systems for power generation;

Dust suppression for mineral processing, conveyors and roads;

Toilet flushing; and

Fire protection.
