20.3.1 Application of water from irrigation water supply system for irrigation

                             

Quantification approach   


Data source

Harvey Water: SCADA system.

 

Data provider

Harvey Water.

 

Method

The volume of water used by consumers within the irrigation water supply system is the total allocation diversion minus any leakage and external trade, as shown in the table below.

 

 

 

Volume (ML)

 

19.8.8 Allocation diversion into the urban water supply system

46,212

Less

Leakage from irrigation supply system (see line item 15.2.4)

2,972

Less

13.6.2 Delivery of traded-in water to connected surface water

1,500

 

Total water consumed

41,740

 

Uncertainty

This value is estimated to be in the range of +/- 5-10%.

 

Approximations, assumptions, caveats/limitations

It is assumed that all the water diverted to the irrigation supply system, and not lost via leakage, is entirely consumed by the users.
