Register of Private Water Supplies in Northern Ireland (2019)

The Drinking Water Inspectorate maintains a register of private water supplies in Northern Ireland as required by the Private Water Supplies Regulations (Northern Ireland) 2017. This spatial dataset represents registered supplies as 100m by 100m square polygons, created on 5th June 2019 and superseded on 28th August 2019. The data is provided by the Government Digital Service via the eu_open_data platform.

Use Cases

• Mapping the distribution of private water supplies based on the polygon layer.
• Monitoring compliance with drinking water regulations for supplies to public or commercial premises.
• Analyzing historical and current private water supply coverage for planning purposes.
• Integrating supply locations into environmental dashboards for visualisation.

Strengths

• Data is explicitly required and maintained by a regulatory body (the Drinking Water Inspectorate).
• Dataset includes both current and historically monitored supplies, providing temporal context.
• Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.

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• The dataset was superseded in August 2019; its current operational status is unclear.
