The Minister for Water has received an application to amend Western Water’s Werribee system bulk entitlement in line with the Water Act 1989. The amendments will allocate the unallocated share of Lake Merrimu to Western Water and make some other changes to improve the clarity of the document.

Application overview

The amendments to Western Water’s Werribee system bulk entitlement are required to allocate the unallocated 10 per cent inflow and 20 per cent storage capacity share of Lake Merrimu to Western Water and make some other changes to improve the clarity of the document.

More information about the application for amendments to reflect the allocation of the unallocated share of Lake Merrimu to Western Water

When previous water rights were converted to bulk entitlements, a 20 per cent inflow share and 20 per cent storage share of Lake Merrimu remained unallocated. In line with Action 4.28c of the Central Region Sustainable Water Strategy, a 10 per cent inflow share was allocated to the Victorian Environmental Water Holder in 2011. In line with Action 4.24 of the Central Region Sustainable Water Strategy, DELWP has been negotiating the allocation of the permanent entitlement to the remaining unallocated 10 per cent inflow share and 20 per cent storage share of Lake Merrimu with Western Water. These negotiations are now complete, and the Minister for Water has approved the allocation of this water to Western Water.

Western Water has applied for bulk entitlement amendments to allocate the unallocated share of Lake Merrimu.  This will increase Western Water’s inflow share of Lake Merrimu from 70 per cent to 80 per cent and its share of storage capacity from 60 per cent to 80 per cent.  There are also some other minor changes to bring the wording of Western Water’s Werribee bulk entitlement in line with other bulk and environmental entitlement in the Werribee system and improve the clarity of the document.

As the 10 per cent inflow and 20 per cent storage share of Lake Merrimu is currently unallocated (not held by any entitlement holder), the allocation of this water to Western Water will not affect the other entitlement holders in the Werribee system – the Victorian Environmental Water Holder and Southern Rural Water (which supplies water to Werribee system water share holders).  It will also not affect the passing flow requirements downstream of Lake Merrimu.

Next steps

The Minister for Water will consider the application from Western Water taking into account the requirements of the Water Act 1989. Subject to the Minister for Water’s approval, the bulk entitlement amendments will come into effect when they are published in the Victoria Government Gazette.
