NUAR is a government digital service, operated by Ordnance Survey, that provides instant access to a secure and standardised map of the underground pipes and cables in England, Wales, and Northern Ireland. It is improving the efficiency and safety of the way we install, maintain, operate, and repair our buried infrastructure. It achieves this through:
- Instant access to data reducing the number of organisations to be contacted and speeding up the average six days to get information.
- Providing a standardised view of underground asset data, which simplifies the previously complex process of aligning varied formats and scales.
There are around 4 million kms of underground pipes and cables in the UK, and 60,000 accidental strikes on these every year - costing the UK economy £2.4 billion per annum and putting workers’ safety and lives at risk. NUAR is envisaged to deliver over £400 million per year of economic growth through increased efficiency, reduced asset strikes and reduced disruptions for the public and businesses.
NUAR will provide secure access to data from over 600 public and private sector asset owners. Data is currently available from over 360 asset owners, including most of the major energy and water providers, several major telecommunications companies, transport organisations, and local authorities. Currently over 3.2 million kms of pipes and cables are mapped, which covers 80% of the known underground assets.
