Description
A spatial dataset of registered private water supplies in Northern Ireland, intended for human consumption but not provided by the public utility. The Drinking Water Inspectorate maintains a register of supplies to public, commercial, or multiple private dwellings, updated at least quarterly, with a recent update noted for September 2023. Data is represented as 100m by 100m square polygons randomly placed around each supply location.
Use Cases
Mapping the distribution of private water supplies based on the spatial polygon layer.
Monitoring regulatory compliance for water quality based on the register of supplies.
Assessing public health risks by identifying supplies serving commercial or multiple dwellings.
Creating dashboards for water supply oversight based on the described analytical suitability.
Strengths
Includes both current and historically monitored supplies, providing temporal depth.
Updated at least quarterly, with a stated next update due in December 2023.
Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
The 100m by 100m squares are randomly placed around supplies, which may limit precise location analysis.
