Wastewater
Coal seam gas water
Ecological Engineering
Direct use, chemical treatment, partial desalination and/or blending to achieve “agricultural grade”, with beneficial re-use by irrigation to trees or crops.
Conventional Engineering
Process based water treatment via desalination, ion exchange or similar, storage of waste brine, and piping of treated water to conventional storages / distribution infrastructure.

Intercepted mine water
Ecological Engineering
Direct use, chemical treatment and/or partial treatment to achieve “agricultural grade”, with beneficial re-use by irrigation to trees or crops.
Conventional Engineering
Impoundment in large, plastic-lined holding ponds, evaporation and rehabilitation of impoundment post mining.
Sewage effluent and sanitation
Ecological Engineering
Direct use, chemical treatment and/or partial treatment to achieve “agricultural grade”, with beneficial re-use by irrigation to trees or crops.
Conventional Engineering
Options include:
- Irrigation of secondary treated water to trees/crops to neutralise contaminants and beneficially use nutrients.
- Release of secondary treated water to wetlands to neutralise contaminants and remove nutrients (may require periodic harvesting to avoid nutrient saturation).and
- Full water treatment via underground wetland to neutralise contaminants and remove nutrients.
