Our unique SuDS Infiltration Suitability Map reveals the locations best suited to sustainable drainage to meet new compliance standards for planning submissions.

Government policy for England is to introduce SuDS to control site rainfall runoff via conditions in planning approvals. Infiltration into the ground is the preferred method for managing surface water runoff on site without increasing flood risk downstream.
Property professionals must assess the feasibility of infiltration SuDS at an early stage in support of the site development process. This will allow outline site assessment of the cost implications and initial master planning of the development prior to the requirement for detailed design.
Lead Local Flood Authorities also need clear guidance on the site suitability for infiltration SuDS when they are assessing proposed developments.
GeoSmart SD50 provides an assessment of the capacity of the ground to receive infiltration depending on the nature, thickness and permeability of the underlying material and the depth to the high groundwater table.
