This data product is not a replacement for a soakaway test or site investigation, rather a tool to support SuDS practitioners in their initial desk-based scoping of SuDS feasibility. Two versions of the data product are available: Infiltration SuDS Map: Summary and Infiltration SuDS Map: Detailed. Infiltration SuDS Map: Summary This package comprises four maps that provide an overview of ground suitability for infiltration SuDS. It does not provide any information about the properties of the subsurface. It is purely intended as a dataset for strategic planning. The Summary package consists of the following layers: - Groundwater protection summary - Infiltration constraints summary - Ground stability summary - Drainage summary Infiltration SuDS Map: Detailed This package comprises the four summary layers included within the Infiltration SuDS Map: Summary, plus an additional twenty data layers, containing a wealth of subsurface property information that can be used to make a preliminary assessment of the suitability of the subsurface for infiltration SuDS. The Detailed package consists of the following layers: - Groundwater protection summary - Groundwater source protection zones - Presence of artificial ground - Predominant groundwater flow mechanism - Infiltration constraints summary - Landslide constraints - Artificial ground constraints - Shallow groundwater constraints - Shallow mining (non-coal) constraints - Soluble rock constraints - Ground stability summary - Collabsible ground - Compressible ground - Landslides - Running sands - Shallow mining - Soluble rocks - Shrink-swell - Drainage summary - Bedrock permeability - Depth to water table - Geological indicators of flooding - Superficial deposit permeability - Superficial deposit thickness Layers are provided as GIS vectorised 50 m grids at 1:50,000 scale providing 50 m ground resolution with text descriptions and a numeric score field indicating the suitability of the ground for infiltration.

The only exception was the superficial thickness data layer, which was not attributed with a score classification. The four summary maps were derived from the rasterised component datasets. For each raster cell, the maximum score from the individual datasets was calculated and used to create the summary map. This is the second version of the Infiltration SuDS map.
