Register of Private Water Supplies in Northern Ireland, July 2020

Northern Ireland's Drinking Water Inspectorate maintains a register of private water supplies for human consumption, as required by the Private Water Supplies Regulations (Northern Ireland) 2017. The dataset consists of 100m by 100m square polygons randomly placed around registered supply locations, including both current and historically monitored supplies. This spatial layer was created by the Government Digital Service on 6th July 2020.

Use Cases

• Mapping the distribution of private water supplies based on the provided geospatial polygons.
• Analyzing compliance and monitoring coverage for water safety regulations mentioned in the description.
• Identifying areas reliant on private supplies for human consumption for public health planning.
• Visualizing historical and current water supply monitoring points in dashboards, as suggested by the description.

Strengths

• Data is explicitly tied to a legal requirement (The Private Water Supplies Regulations (Northern Ireland) 2017), providing a clear regulatory context.
• Includes both current and historically monitored supplies, offering a temporal dimension.
• Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset was superseded on 7th October 2020, indicating it is not the current version.
