A delivery share is an entitlement to have water delivered to land in an irrigation area. It gives you access to a share of the available capacity in the channel or piped network that supplies water to your property. A Delivery Share is defined by a rate of megalitres per day (ML/day).
A delivery share is tied to the land and stays with the property if it is bought or sold. Delivery shares do not transfer off the land when the water shares are sold.
In July 2006, 12 months prior to the unbundling of land and water, Goulburn Murray Water introduced the rule that when water shares (previously called permanent water) were sold off the farm, the infrastructure costs stayed with the farm. Infrastructure costs referred to the cost of the channels/piping of the water. Once land and water unbundled in July 2007, infrastructure costs were renamed to Delivery Shares.
The benefit of a Delivery Share is that in periods of high demand on a channel system, the delivery share rate is used by the Water Authority to determine how deliveries are rationed.
