Looking to the future:
Continuous Sharing
Continuous sharing …
• Is a method of water accounting• Used in Victoria for large electricity customers in Gippsland• Used in areas of Queensland since 1999• Growers interest is growing in other parts too • Growers have increased production without increasing water use
through better water management due to continuous sharing
Continuous sharing provides more individual choice and requires more decision making.However – customers can choose to take standard allocations if they want.
Example of continuous sharing…
Reservoir Inflows less storage losses and environmental flows
Outflows plus delivery losses
Your storage share…

When your storage share is full it spills into un-filled storage shares
Your storage share…

Outflows plus delivery losses
Inflows less storage losses and environmental flows
You share in storage inflows based on your entitlement
You share in storage losses based on the volume you have stored
Your storage share…
Reservoir
Outflows plus delivery losses
Inflows less storage losses and environmental flows
Your storage share volume increases with inflows and decreases with losses

What are the benefits of continuous sharing?
• You manage your water share at the storage• No annual allocation made for the district • There is no reset at the end of the season for water shares• The maximum you can store is limited by the size of your water share• The maximum you can use in a season is capped• The maximum you can use is reset at the end of a season• You can separately trade: water, water share and seasonal caps• The legal water entitlement you currently hold remains the same• The maximum volume in your storage depends on entitlement• You share inflows based on your entitlement• You share storage losses based on the volume you store• Your use includes delivery losses• The water you have depends on inflows, losses, use and trades • More flexibility can provide greater certainty and planning horizon
It is like having your own storage
What next …
• Are you interested?• Customer support – If strong, proceed with initial study• Legislative changes are required – it will take time
• Develop model to suit local conditions • Develop information package for customers • Run information sessions and inform customers on continuous
allocation use
