Register of Private Water Supplies in Northern Ireland as of December 2019

A register of 100-meter grid squares representing private water supplies for human consumption not provided by the public utility. The Drinking Water Inspectorate maintains this spatial dataset, which includes supplies to public, commercial, or multiple private dwellings. This version was created on December 31, 2019, and includes both current and historically monitored supplies.

Use Cases

• Mapping the distribution of private water supplies based on the spatial grid layer.
• Monitoring regulatory compliance for supplies to commercial premises as mentioned in the description.
• Assessing historical changes in water supply monitoring based on the inclusion of past records.
• Integrating supply locations into public health dashboards for visual analysis.

Strengths

• Data is explicitly tied to a legal register required by the Private Water Supplies Regulations (Northern Ireland) 2017.
• Includes both currently and historically monitored supplies, providing a temporal dimension.
• Available in multiple geospatial formats (KML, GeoJSON, ESRI SHAPE) for interoperability.

Limitations

• Row count and specific data scale are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset was superseded in April 2020, indicating it is not the current version.
