Register of Private Water Supplies in Northern Ireland, 2023

The Drinking Water Inspectorate holds a register of private water supplies in Northern Ireland under the Private Water Supplies Regulations (Northern Ireland) 2017. This spatial dataset represents registered supplies as 100m by 100m square polygons, including both current and historical monitoring records. The dataset was created on 30 September 2023 and superseded on 31 December 2023.

Use Cases

• Mapping the distribution of private water supplies based on the spatial polygon layer.
• Analyzing regulatory coverage for public or commercial premises based on the register requirement.
• Identifying areas reliant on non-public water sources for human consumption.
• Supporting environmental health inspections by locating registered supplies.

Strengths

• Data is explicitly tied to a legal register requirement under the Private Water Supplies Regulations (Northern Ireland) 2017.
• Includes both currently monitored and historically monitored supplies, providing temporal context.
• Spatial data is provided in multiple standard formats including GeoJSON, KML, and ESRI Shapefile.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset was superseded on 31 December 2023, indicating it is not the current version.
