Register of Private Water Supplies in Northern Ireland, June 2023

A June 2023 spatial dataset from the Drinking Water Inspectorate (DWI) containing a register of private water supplies in Northern Ireland. The data is represented as 100m by 100m polygons randomly placed around registered supply locations and includes both current and historically monitored supplies. It was created by the Government Digital Service and superseded in September 2023.

Use Cases

• Map the distribution of private water supplies based on the described spatial polygon layer.
• Monitor regulatory compliance for water intended for human consumption based on the register mandate.
• Analyze the coverage of water safety inspections for public, commercial, or multi-dwelling premises.
• Support public health risk assessments by identifying non-public water supply locations.

Strengths

• Data is explicitly spatial, provided as polygons in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON).
• Includes a defined temporal snapshot with a specific creation date of 15 June 2023.
• Covers both currently and historically monitored supplies, providing some temporal depth.
• Derived from an official regulatory register maintained by the Drinking Water Inspectorate.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset was superseded on 30 September 2023, indicating it is not the current version.
