1 Sydney Water Corporations's unregulated entitlements from the Hawkesbury and Lower Nepean rivers water source. Sydney Water Corporation uses these entitlements to supply water to its North Richmond Water Treatment Plant. The Sydney Catchment Authority supplies water to all Sydney Water Corporation's other water treatment plants from its storages/weirs. These supplies are based on the authority's regulated entitlements and the bulk supply agreement between the two organisations.




Quantification approach

Data source

Water Sharing Plan for the Greater Metropolitan Unregulated River Water Sources. Water management registers, licence and trading statistics (for Kangaroo River Water sharing plan area) and individual licence information.

Provided by

New South Wales Office of Water.

Method

Mapping entitlement values stated in the Water Sharing Plan for the Greater Metropolitan Unregulated River Water Sources, water management registers and licences and trading statistics to the relevant categories of entitlements.

Assumptions, limitations, caveats and approximations

The total water right for the region is assumed to be 100% of the entitlement.

Uncertainty information

Estimated uncertainty is +/– 0% to 5% based on professional judgment and the established practice within the New South Wales Office of Water.
