Joint Private Works Schemes

A private water scheme is an arrangement among a group of landowners to share the costs and responsibilities of establishing and maintaining a private water system, including pumps, pipelines, channels, and related infrastructure.

This asset provides the mapped boundaries of Joint Private Works Schemes in New South Wales, including the parcels within each scheme. In early 2024, NSW Public Works mapped these scheme boundaries within a single spatial (GIS) dataset, using the NSW cadastre reference from February 2024 and a GDA2020 datum.

Two types of schemes have been mapped: 1) Private Water Corporations. 2) Private Water Trusts.

The scheme boundaries were mapped using the following methods (priority order): (i) Georeferencing images of gazetted maps to the NSW cadastre to align and match boundaries. (ii) Following boundary descriptions in gazettal notices, with georeferencing of near-date Parish Plans and tracing of natural features from NSW Spatial Services imagery. (iii) Using a gazetted schedule of parcels. (iv) Referring to Parish Plans where schemes and trusts were mapped.

Collaboration: DCCEEW (Water Group), NSW Public Works, DPI. DPI created the spatial files and PDF documentation.
