This session has been developed over the past ten years by Chris Griffiths, Marshalls’ SuDS expert. The presentation aims to explain basic Sustainable Drainage principles and understand their position within a wider water management hierarchy, from Natural Flood Management techniques right through to heavily engineered underground storage systems. We will explore changes and improvements in SuDS guidance and legislation and discuss what this means for both new developments and retrofit schemes in the UK.
There will be a detailed guide to the specification of Concrete Block Permeable Paving (CBPP), as well as a walkthrough of how to design robust and long-lasting CBPP systems, which balance structural and hydraulic requirements. The opportunity to save time, cost and carbon by designing outside of the British Standards will also be explored during this session.
The final section explores some of the most persistent myths, which surround SuDS and permeable paving – effectively, the most common excuses we hear from developers who are confused about the specification, design, installation or maintenance of these cost-effective and time-proven systems. We will present designers with the information and evidence they need to overcome these objections, allowing them to confidently design quality sustainable drainage systems into their projects.
