20.6.3 Volume of potable water export

                             

Supporting information   


Shoalhaven City Council exported 2,574 ML of potable water from its distribution system to its service area in the Clyde Catchment, which is outside of the Sydney region.

 

Quantification approach   


Data source

Shoalhaven City Council’s water billing records and the telemetry system.

 

Data provider

Shoalhaven City Council.

 

Method

Metered customer-use data, extracted from billing records, were used to determine the potable water export.

 

Uncertainty

The volume was estimated from measured data. Estimated uncertainty, based on meter accuracy and professional judgment on determination of boundaries of billing areas beyond the Sydney region, is +/–5%.

 

Approximations, assumptions, caveats/limitations

The compilation of data for the line item has been difficult due to the Sydney region not aligning with the boundaries of Shoalhaven City Council. All effort was made by the council to ensure data provided here are as accurate, on a suburb/location basis, as possible.
