REUSE WATER
 
Reuse or recycled water is an important option for securing water supply into the future. There is increasing investment in infrastructure related to the supply of reuse water, and as such there is considerable interest in the volumes of reuse water supplied and used. Reuse or recycled water is provided for purposes including: agricultural irrigation; 'third pipe' systems in new urban developments; watering of community sports grounds and parks; and supply to industry. In addition, water management authorities are interested in whether reuse water is reducing the demand for distributed water or self-extracted water.
 
In 2009–10, the total volume of reuse water supplied was 374 GL, more than a third (34% or 127 GL) was supplied in New South Wales and more than a quarter (26% or 98 GL) in Victoria.
 
The Agriculture industry remained the largest user of reuse water across all industries in Australia (34% of total reuse water or 126 GL) followed by the Water supply industry (28% or 105 GL) and by Other industries (21% or 78 GL). Other industries includes industries relating to the operation and maintenance of parks, gardens and sporting fields (see the Glossary for a complete list of Other industries).

ORIGIN OF REUSE WATER
 
The table below presents reuse water supply (see Explanatory Notes, paragraph 17) by type of water supplier in 2009–10. Of the total 412 GL of reuse water collected, 87% (357 GL) came from wastewater with the remainder coming from drainage and stormwater. It is likely that drainage water from irrigation/rural water providers makes a significant contribution to reuse water supply, but this is mostly unmeasured. In some cases, distributed water can also be mixed with reuse water. Of the States and Territories, reuse water supply from wastewater was highest in Victoria (117 GL or 33%), followed by Queensland (79 GL or 22%).

(a) Reuse collected may be either supplied to customers or used by the Water supply industry.

 
The table below describes the supply of distributed water and reuse water by water providers. 59% of the distributed water in Australia was supplied by irrigation/rural water providers, more than a quarter by major urban water providers (26%). In New South Wales, 70% of all distributed water in the state was supplied by irrigation/rural water providers. In contrast, 61% of reuse water in Australia was supplied by major urban water providers and only 19% by irrigation/rural water providers.
