This report presents a description of the ''Infiltration SuDS Map: Detailed'' developed by the British Geological Survey (BGS). The dataset provides subsurface information enabling preliminary assessment of the ground for infiltration sustainable drainage systems (SuDS). The map can be used in relation to any type of infiltration SuDS including soakaways, infiltration basins and permeable pavements. The map is designed to be used by those interested in the properties of the ground for the installation of infiltration SuDS, but it is not an alternative to a ground investigation. It may be particularly valuable for developers, planners and local authority SuDS approval officers, who need to either assess the properties of the ground directly, or assess planning application for SuDS.

The ''Infiltration SuDS Map: Detailed ''comprises of twenty-four individual GIS (geographical information system) layers, which are structured under the following headings: infiltration constraints, drainage potential, ground instability and groundwater protection. The GIS layers under each heading include up to seven individual data layers showing the properties of the ground and a summary layer, which provides an overview of the information contained within those data layers highlighting overall suitability.

More information about pricing and licensing the Infiltration SuDS Map is provided at [http://www.bgs.ac.uk/products/hydrogeology/infiltrationSuds.html http://www.bgs.ac.uk/products/hydrogeology/infiltrationSuds.html].

For those involved in the <u>strategic assessment</u> of ground conditions for the installation of infiltration SuDS, the ''Infiltration SuDS Map: Summary ''may be more appropriate. This map provides an indication of the suitability of the subsurface for infiltration SuDS, but does not provide any specific information about the properties of the ground.

The methodology employed in creating this dataset has been critically assessed by Dr V Banks and Dr D Aldiss who specialise in hydrogeology and in geological derived products at BGS. The dataset has also been reviewed by seven external experts and improvements have been made based on their suggestions. The purpose of this user guide is to enable those licensing the ''Infiltration SuDS Map: Detailed ''to have a better appreciation of how the dataset has been created and therefore a better understanding of its potential applications and limitations.
