Register of Private Water Supplies in Northern Ireland as of April 2020

A spatial dataset of 100m by 100m squares randomly placed around registered private water supplies in Northern Ireland. The register, required by the Private Water Supplies Regulations (Northern Ireland) 2017, includes supplies to public, commercial, or multiple private dwellings used for human consumption. This dataset was created by the Drinking Water Inspectorate on 24th April 2020 and superseded on 6th July 2020.

Use Cases

• Mapping the distribution of private water supplies based on the spatial polygon layer.
• Monitoring compliance with water quality regulations for supplies to commercial premises.
• Analyzing historical and current water supply coverage for dwellings not served by the main utility.

Strengths

• Dataset is based on a legal register required by the Private Water Supplies Regulations (Northern Ireland) 2017.
• Includes both currently and historically monitored supplies, providing temporal context.
• 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.
• Dataset was superseded shortly after its creation in July 2020, indicating it may not be current.
