Register of Private Water Supplies in Northern Ireland, January 2021

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 squares for visualization and analysis. The dataset was created on 6th January 2021 and superseded on 30th March 2021.

Use Cases

• Visualize the spatial distribution of private water supplies based on the polygon layer.
• Analyze compliance monitoring coverage for supplies to public or commercial premises.
• Dashboard integration for tracking historically monitored private water supplies.
• Identify areas reliant on private water for drinking and domestic purposes.

Strengths

• Data is explicitly tied to a legal register mandated 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, 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• The dataset was superseded in March 2021; its operational currentness is unclear.
