ACT Stormwater Headwall and Endwall Locations with Asset Attributes

ACTGOV Headwall Assets is a point dataset showing the locations of stormwater headwalls and endwalls in the Australian Capital Territory. The data is owned or managed by the City and Environment Directorate and includes attributes such as location description, suburb, ownership, asset sub-type, and construction details. Assets are captured through the works-as-executed handover process or field audits and were last updated on 2026-04-04.

Use Cases

• Map stormwater drainage infrastructure based on location and asset sub-type attributes.
• Analyze asset ownership and maintenance responsibility for municipal planning.
• Model water flow and drainage capacity using surface and invert level data.
• Assess construction materials and apron types for infrastructure maintenance planning.

Strengths

• Data is sourced from an official government asset database managed by the ACT Government.
• Attributes include specific engineering details like surface/invert level, height, material, and construction type.
• Data is available in multiple geospatial formats including GPKG, GeoJSON, and a REST API.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset may not include assets owned privately or by other government directorates.
