SuDSmart Reports - Sustainable Drainage Design (SuDS)

Sustainable Drainage Assessment (SuDS) Screening Report

What does it solve?

Planning applications require the developer to explore suitable SuDS options, starting with infiltration drainage. Whether infiltration can be achieved or not depends on the capacity of the ground to receive water.

The SuDSmart Plus Report is the second in our range of SuDS Reports designed to explore suitable SuDS options.

The report is based on GeoSmart’s innovative SuDS Infiltration Map, showing a site’s infiltration suitability (low, moderate, high) on a 50m grid providing total confidence during the early conceptual design stage.

SuDSmart Plus includes all the features of a SuDSmart Report with the additional consideration of potential infiltration issues, runoff volumes and flows for initial design and discussion with the regulator.

The report typically supports developers and regulators in support of planning by creating and evaluating an appropriate drainage system for a site.

Need more detail to develop a feasibility study and strategy for SuDs for your development? Our SuDSmart Pro Report provides the answer.

Reports based on :

  • Development site is equal to a single residential/small commercial building footprint
  • A site location plan is available
  • Proposed development plans are provided
  • For new developments, areas of permeable and impermeable ground cover should be pre-calculated and provided
  • SuDS components have not already been included in the final design
  • A site walkover survey is not required
  • A selection of recent site photographs are available
  • Advance payment is made

If your site doesn’t fit these assumptions or you require more detailed assessment, we can still assist but please do get in touch as one of our other packages may suit you better.
