Successful Delivery Index

12


What does it measure?• Two important aspects of supply are:

● Accuracy● managing what you measure

● Reliability● Changes to bay irrigation times● Changes to infiltration rates● Lead to on-farm inefficiencies or excess run-off or both

• The SDI provides a measure of supply reliability

13


What is it?

Success or fail on the basis of whether the delivered flow was within ±10% of the ordered flow or

±0.5 ML/day (whichever is greater) for 95% of the order duration

Root Cause Analysis

23

Conclusion

• Customer and staff acceptance along with grasping the potential of the system has been very positive after some shaky beginnings!

• The benefits to production, the water savings, lifestyle, occupational health and safety - are real

• Modernisation produces a data rich environment highlighting the problems within the channel system

• Modernisation projects inherit the problems of the past• Modernisation projects are about change, the construction

is easy, the real challenge is managing the change resulting on both sides of the meter
