Western Australia Sewerage Policy Spatial Data

The Government Sewerage Policy (2019) sets the State Government's position on sewage service provision for land planning and development in Western Australia. It guides strategic planning and subdivision, promoting reticulated sewerage as the primary disposal method and detailing requirements for on-site systems where unavailable.

Use Cases

• Analyze spatial compliance of new subdivisions with the policy's requirement for connection to reticulated sewerage where available.
• Map areas where on-site sewage treatment is permitted based on policy-defined site requirements for health and environmental grounds.
• Support strategic land planning by integrating policy guidance on sewage disposal methods for future development projects.

Strengths

• Policy is formally defined and dated (2019), providing a clear regulatory framework.
• Data is maintained by the authoritative Department of Planning, Lands and Heritage.
• Offered in multiple spatial formats (WFS, GeoJSON, SHP) for interoperability.

Limitations

• Dataset size and record count are unknown, limiting assessment of granularity.
• Specific data columns and sample records are unavailable, obscuring the exact attribute schema.
