NET WATER SUPPLY
 
Net water supply is the quantity of water actually supplied to users in the economy and equates to total distributed water less bulk water, losses, environmental flows and own use by the Water supply industry.
 
The table below presents the total net water supply, by States and Territories, in 2009–10, both for distributed water and reuse water. Net distributed water supply was 6,870 GL while net distributed reuse water was 247 GL.

WATER DISCHARGES
 
In Australia, the total volume of regulated discharge (see Explanatory Notes 18-19) to the environment in 2009–10 was 51,912 GL. The Electricity and gas supply industry discharged about 95% of this total or 49,470 GL due mainly to the large amount of water used in hydro-electric power generation. The Water supply industry accounted for nearly 3% (1,593 GL) of the total water discharges. Of these discharges, 38% (606 GL) occurred in New South Wales, 22% (350 GL) were in Queensland and 20% (315 GL) were in Victoria.
 
The table and graph below show water discharges made by the Water supply industry to various water bodies. Of the total 1,593 GL of water discharged by the industry in 2009–10, about 68% was discharged to the sea, 30% to inland surface water and 1% to groundwater.
