Corrosivity Map for the UK

The dataset is a Soil Corrosivity Map for the U.K. based on the BGS DIGMapGB-PLUS Map. The creation of this dataset involves scoring the Soil Parent Material types for five different attributes that contribute towards the corrosion of underground assets. These are (i) high or low soil pH, (ii) general soil moisture, (iii) the likelihood that soil saturated and undergo periods of anaerobic conditions, (iv) the presence of sulphides and sulphates and (v) the resistivity of the soil parent material

What's in it

Data offered docs-verified: soil corrosivity classification map for the UK (three categories) · GIS layer of ground corrosion risk to underground cast iron assets · soil parent material scoring for pH, moisture, anaerobic conditions, sulphides/sulphates and resistivity
Coverage docs-verified: United Kingdom
Update frequency docs-verified: asNeeded
Access docs-verified: No authentication listed. Dataset licence not set on the page; access constraints restrict reproduction without BGS/NERC permission. Site footer cites OGL v3.0 generally.

Useful for

Use cases llm-inferred: Screening buried cast iron or ferrous utility mains for replacement priority by ground corrosivity class · Desk-based ground corrosivity screening for pipe material selection on a new civils or drainage scheme · Corrosion-risk layer for asset management plans covering underground ferrous assets across a UK region
Audience llm-inferred: water utility asset managers · civils engineers · utilities and pipeline engineers · planners · geotechnical engineers

Limitations

Constraints llm-inferred: Three-class categorical output (unlikely / may / likely), not a continuous corrosion rate · Scoring follows the CIPA/DIPRA cast iron rating system, so it is tuned to ferrous assets · Based on soil parent material mapping, so not site-specific; site investigation needed to confirm · Dataset reference date is 2011-10-10, so the underlying data may be dated · Licence unclear: dataset licence not set and reproduction restricted without BGS/NERC permission · BGS and NERC give no warranty as to the quality or accuracy of the information
