The mapped boundaries of Private Water Corporations within the State of NSW and the parcels within them are described. Private Water Corporations are former private irrigation districts and private drainage boards and unions. In the first half of 2024 the boundaries of the Private Water Corporations were mapped by NSW Public Works within a single spatial (GIS) dataset using a reference NSW cadastre from February 2024 and a datum of GDA2020. The Private Water Corporations boundaries were mapped using the following methods in descending order: Georeferencing images of gazetted maps to the NSW Cadastre and matching boundaries. Following gazetted boundary descriptions. This would typically require georeferencing an image of a Parish Plan that was published at a similar date to the gazettal notice to provide context to the descriptions. NSW Spatial Services Aerial Imagery was traced when descriptions or maps referred to physical boundaries like creeks, rivers, and water channels. Using a gazetted schedule of parcels. Using Parish Plans when Private Water Corporations were mapped on them. The list of Private Water Corporations and the references to gazettal notices was provided by the Water Group, Department of Climate Change, Energy, the Environment and Water, NSW Government.

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, listed in descending order of priority: i) Georeferencing images of gazetted maps to the NSW cadastre to align and match boundaries. ii) Following boundary descriptions as detailed in gazettal notices, often requiring georeferencing of Parish Plans published near the gazettal date for contextual accuracy. NSW Spatial Services aerial imagery was traced when descriptions or maps referenced natural features like creeks, rivers, or water channels. iii) Using a gazetted schedule of parcels. iv) Referring to Parish Plans where Joint Private Works Schemes and Trusts were mapped. The Water Group, Department of Climate Change, Energy, the Environment and Water (DCCEEW), provided the list of Joint Private Works Schemes and references to the gazettal notices. This project is a collaborative effort between DCCEEW, NSW Public Works, and the Department of Primary Industries (DPI), with DPI creating the spatial files and PDF documentation for the Joint Private Works Schemes.

These datasets represent management units within in-force water sharing plans across NSW, including regulated, unregulated and groundwater plans (or a combination of these). The data includes both water sources and management zones (where applicable) derived from plans gazetted under the NSW Water Management Act 2000. The boundaries of these water sources and management zones are used to define areas in which specific management rules apply. As such, this data may be used to understand which water sharing plan rules apply to a specific location. The plans are in place for 10 years but may be amended within this time. Any updates to water source or management zone boundaries as a result of a plan being amended during, or replaced following its 10 year term will be made available at that time.
