Legislation
PPG25 states that every new development should undergo a flood risk assessment before submission for planning permission and promotes the use of 'Substainable Urban Drainage Systems' (SUDs) to achieve this.
The content of this website is based on Naylor's solutions to stormwater management and products related both to controlling flash flooding and recycling/reusing rain water (water harvesting).
Current guidance/legislation promotes a more sustainable approach to drainage design replicating nature.
