Inter?basin delivery of water refers to the process of moving water from a source basin (catchment) to a recipient basin. The approach has been controversial at times because of both perceived and actual impacts on the source basin and the receiving basin. There are examples of negative impacts arising from schemes in this country and overseas. Rigorous controls and assessment processes are available for determining how Inter?basin deliveries can be achieved sustainably. These need to be applied meticulously in determining when and how inter?basin delivery can occur. AWA believes that inter?basin deliveries are a legitimate means of accessing water, and should be considered equally with all alternatives, including non?supply options such as demand management and water conservation. If well researched, planned, implemented, monitored and adapted in response to unforeseen issues, inter?basin delivery can be a successful water supply strategy.
