Surface Water Assessor
Assessing the potential for SuDS retrofit opportunities
Surface Water Assessor helps determine the potential for sustainable drainage system (SuDS) retrofit opportunities by producing visual geographical information system (GIS) outputs and excel calculations. These outputs are designed to give you both a qualitative and quantitative assessment of a region—such as the locations and types of opportunities, the impermeable area it may be able to drain, flow paths and their elevation profiles, and overall cost.
The Surface Water Assessor draws on data from a variety of sources including address point data, LiDAR digital terrain models, open street mapping, Ordnance Survey MasterMaps, road centerline data, sewer network data, and watercourse data.
Stantec’s digital approach enables the automated identification of opportunity and the ability to improve outputs through user specifications.
