Register of Private Water Supplies in Northern Ireland, October 2020

The Drinking Water Inspectorate maintains a register of private water supplies in Northern Ireland as required by the 2017 regulations. This spatial dataset represents registered supplies as 100m by 100m squares, including both current and historically monitored sources. The dataset was created on 7th October 2020 and superseded on 6th January 2021.

Use Cases

• Map the distribution of private water supplies based on the spatial polygon layer.
• Monitor compliance with water safety regulations for public or commercial premises.
• Analyze historical trends in private water supply monitoring based on the inclusion of past records.
• Create dashboards for visualizing water supply coverage and oversight areas.

Strengths

• Dataset is explicitly required and maintained by regulation (The Private Water Supplies Regulations (Northern Ireland) 2017).
• Includes both current and historically monitored supplies, providing temporal context.
• Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.

Limitations

• Dataset was superseded in January 2021; it is a historical snapshot and not current.
• Row count and specific column definitions are unknown, limiting suitability assessment.
• The spatial representation uses 100m squares randomly placed around supplies, not precise point locations.
