3.4 Urban inter-region claim on water

Supporting information

SA Water hold a Class 6 water access entitlement (WAE) to 130,000,000 shares in the River Murray consumptive pool for South Australia. The WAE is intended specifically for reticulated public water supply to metropolitan Adelaide. The Mannum–Adelaide, Murray Bridge–Onkaparinga and Swan Reach–Stockwell pipelines are used to transfer River Murray water under the entitlement. The water allocation rate can exceed one kilolitre per unit share because the entitlement is managed as a rolling total diversion of 650 gigalitres over five years.

Carry-over of water allocated against the Class 6 WAE is not permitted (Department for Water 2011); therefore, the volume reported at 30 June 2013 and at 30 June 2012 was 0 ML. More details regarding the entitlement can be found in the Water Allocation Plan for the River Murray Prescribed Watercourse.
