Adelaide

The volume reported in the water accounting statement (19 ML) item represents the volume of water that was held in the Barossa Irrigation Limited (BIL) network.

Data source

Barossa Irrigation Limited (BIL): hard copy map of pipe network.

Data provider

South AustralianDepartment for Water.

Method

Total BIL pipe lengths and corresponding pipe diameters were obtained from a 2009 hard copy map of the BIL pipe network. Lengths and diameters were then used to calculate the total volume stored in the pipes if 100% full, according to the equation:

V = (π × (d/2)² × (L/1000)
where:
  V = volume (ML)
  d = nominal pipe diameter (m)
  L = length of section (m)

An analysis was undertaken to determine the percentage of the BIL pipe network within the Adelaide region.

Uncertainty

Ungraded.

Assumptions, approximations and caveats/limitations

• Pipes were under pressure and therefore were 100% full at all times.
• The 2009 hard copy map of the BIL pipe network was an accurate depiction of the network for 2009–10.
• The nominal pipeline diameters recorded on the map represent the internal diameter of the pipeline.
