Register of Private Water Supplies in Northern Ireland, August 2018

A 2018 spatial dataset of private water supplies in Northern Ireland, registered under the Private Water Supplies Regulations (Northern Ireland) 2017. The Drinking Water Inspectorate maintains this register for supplies serving public, commercial, or multiple domestic premises. Data is represented as 100m by 100m squares randomly placed around registered supply locations.

Use Cases

• Map private water supply locations for regulatory oversight based on the spatial polygon layer.
• Analyze the distribution of non-public water sources for public health risk assessment based on the register's coverage.
• Integrate supply data into environmental dashboards for monitoring based on the description's mention of dashboard use.

Strengths

• Data is explicitly tied to a legal register (The Private Water Supplies Regulations (Northern Ireland) 2017).
• Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.
• Published under the OGL-UK-3.0 license, permitting reuse.

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• The dataset was superseded in March 2019, indicating it is not the current version.
