South Australia’s Strategic Plan is comprised of 100 targets. These targets are specific and measurable and enable us to measure our progress towards achieving the Plan’s visions and goals.

Each target is reported on through this section of the website. Data is analysed and uploaded as it becomes available.

Target:

74. Recycled wastewater:

South Australia has the system capacity to recycle up to 50 GL of wastewater per annum by 2025



Key Measure

 

Explanatory Comments

~~In 2009 (the baseline year), recycled wastewater capacity was 58.3 gigalitres (GL), and is estimated at 71.9 GL in 2015 and 2016. 

Reporting periods are financial years. Recycled wastewater capacity for 2015/16 is therefore indicative (due to data request being March 2016).

For the 2016 assessment, SA Water slightly modified its method for calculating its recycled wastewater capacity (applying from 2014/15) so that it takes into account the full effect of wastewater availability (supply) limitations in addition to wastewater treatment plant capacity. As a result, wastewater reuse for 2014/15, and indicative reuse capacity for 2015/16, are indicated as being marginally lower (3.2 GL) less than was indicated in 2013/14 assessment.

No further capacity augmentations are known to have occurred since the previous SASP reporting period in 2014. However, the Northern Adelaide Irrigation Scheme (NAIS) aims to accelerate the feasibility and design of the NAIS to create a new irrigation area using 20 GL per annum of recycled water from the Bolivar Wastewater Treatment Plant. This project has been identified as a priority by Infrastructure Australia.

This target measures the capacity to recycle wastewater (combined SA Water and local council wastewater schemes), which does not reflect the amount of wastewater that is being recycled on an annual basis.

Wastewater recycling capacity includes both SA Water and estimated local council wasteweater reuse capacity. For the 2016 SASP update, SA Water advises that its reuse capability figure for 2015 (2015/16) differs from previous yearly assessments, by taking  account of both  nominal WWTP daliy capacity and effleunt availability limiations. SA Water data for previous years did not tyake full account of effluent availability limitations.
