Register of Private Water Supplies in Northern Ireland, June 2019

Northern Ireland's register of private water supplies intended for human consumption, maintained by the Drinking Water Inspectorate. The dataset was created on 5th June 2019 and superseded on 28th August 2019. It is provided as a spatial layer of 100m by 100m squares randomly placed around registered supply locations.

Use Cases

• Mapping the spatial distribution of private water supplies based on the 100m grid layer.
• Monitoring compliance with the Private Water Supplies Regulations (Northern Ireland) 2017 for public or commercial premises.
• Analyzing historical and current water supply monitoring coverage by the Drinking Water Inspectorate.
• Supporting dashboard visualizations for water quality and public health oversight.

Strengths

• Includes both currently and historically monitored private water supplies as of the dataset's creation date.
• Covers supplies to public/commercial premises and multi-dwelling private supplies used for domestic purposes.
• Available in multiple geospatial formats (KML, ESRI SHAPE, GEOJSON) for interoperability.

Limitations

• Row count and specific column-level documentation are unknown; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified as the dataset was superseded in August 2019.
• The spatial representation uses randomly placed 100m squares, which may not precisely represent supply point locations.
