5.3 Urban recycled water supply system

                             

Supporting information   


The volume reported in the water accounting statement (225 ML) represents the volume of water that was held in pipes of the SA Water recycled system, including pipes used for delivery of recycled water to Mawson Lakes, Virginia Pipeline and for Adelaide municipal use.

 

Quantification approach   


Data source

SA Water: Geographic Information System (GIS) database.

 

Data provider

SA Water.

 

Method

GIS analysis was used to identify pipes that are part of the recycled water system within the Adelaide region. The volume of water in these pipes was estimated from their total capacity.

 

Uncertainty

Ungraded.

 

Assumptions, approximations and caveats/limitations

  • Pipes were assumed to be 100% full in winter.
  • Pipes without recorded construction dates were assumed to have been constructed before 2009–10.
  • Recycled water schemes not managed by SA Water, such as the Willunga Basin scheme, were not reported on.
