Progressing drainage to sustainable drainage in housing

This free susdrain webinar includes presentations that share approaches to delivering SuDS in new housing developments, de-bunk myths around potential challenges of SuDS delivery and also demonstrate what can be achieved.


While there is growing acceptance of the value and benefits of well-designed Sustainable Drainage Systems (SuDS) there is still some work needed to progress from “drainage” to sustainable drainage. By using SuDS to mimic natural drainage we can achieve more than we would otherwise with traditional drainage, as SuDS provide benefits in flood risk management, water quality, biodiversity and amenity.

Moving beyond compliance of the English Non-statutory Technical Standards for SuDS (and its focus on flood risk management) significantly improves the quality of our housing, as well as our spaces and places.

Together with our supporters and partners we’ve been championing this approach for years and it’s encouraging to see Welsh Government mandate this in their SuDS Standards. While there are some potential challenges and concerns many of these can be overcome through early engagement, good SuDS design and effective integration of SuDS in the development. We can deliver more than a pipe discharging surface water to a pond – this webinar will explain how.

Why attend

The speakers have been involved in SuDS design and delivering SuDS for a number of years. The objectives of the webinar are to

  • Demonstrate what good Design Integration and SuDS integration looks like
  • Explain how integrating SuDS into developments can be beneficial
  • Dispel some common myths around SuDS delivery for residential developments
  • Provide examples of how multi-beneficial SuDS can be delivered
