SuDS Infiltration Suitability Map
Insights from the ground up
Identifying site suitability for sustainable drainage systems (SuDS) schemes for developers, architects and local authorities.
Rated Excellent on Trustpilot
Climate change is compelling local authorities to think smarter about sustainable property development. Reconciling the pressure for housing with better environmental management is bringing forward new guidance on improved site drainage and flood mitigation.
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.

Navigating environmental reports can be complex. We’ve answered the most common queries about our data, timescales, and planning suitability below.
Can’t find the answer? Our consultancy team is here to help.
- Allows preliminary assessment of the site without the need for a bespoke SuDS design
- Use in conjunction with the SuDSmart report range to identify SuDS infiltration suitability and flow/volume design data
- Provides the client with a clear site risk profile on drainage cost and land area needed
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.

I now purchase GeoSmart’s Groundwater Flood Risk maps regularly – always a very speedy response to the both the initial request and, more importantly, delivery of the data! Excellent customer service too. The data is clear and extremely useful for flood risk assessments.
