Register of Private Water Supplies in Northern Ireland, October 2020

A spatial dataset of 100-meter grid squares representing locations of private water supplies registered for human consumption in Northern Ireland. The Drinking Water Inspectorate maintains this register under the 2017 regulations, covering supplies to public, commercial, or multiple private dwellings. This layer, created on 7 October 2020, includes both current and historically monitored supplies.

Use Cases

• Visualizing the spatial distribution of private water supplies based on the polygon layer.
• Analyzing regulatory coverage and monitoring history for water supplies mentioned in the description.
• Integrating supply locations into environmental dashboards for public health oversight.
• Assessing potential risks by overlaying private supply data with other geospatial layers.

Strengths

• Data is explicitly tied to a legal register required by the Private Water Supplies Regulations (Northern Ireland) 2017.
• Includes both current and historically monitored supplies, providing a temporal dimension.
• Available in multiple geospatial formats (KML, GeoJSON, ESRI Shapefile) 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• The dataset was superseded on 6 January 2021, indicating it is not the current version.
