What are Sustainable Drainage Systems (SuDS)
Why are SuDS important?
As urban development increases and climate change leads to more frequent and intense rainfall events, effective surface water management has become increasingly important.
Sustainable Drainage Systems help to:
Reduce the risk of surface water flooding.
Mimic natural drainage processes.
Improve water quality by removing pollutants from runoff.
Reduce pressure on sewer networks and watercourses.
Enhance biodiversity and create valuable habitats.
Support compliance with national and local planning policy.
Deliver climate-resilient drainage solutions for future generations.
Sustainable Drainage Systems (SuDS) are a modern approach to managing surface water runoff by mimicking natural drainage processes by storing, infiltrating, attenuating and treating surface water as close to the source as possible.
SuDS can include a range of features such as permeable paving, swales, detention basins, attenuation ponds, infiltration systems, rain gardens, and wetlands. These measures work together to slow the movement of water through a site, reducing peak runoff rates and helping to manage storm events more effectively.
Frequently Asked Questions (FAQs)
-
A Drainage Strategy for a Planning Application is a technical report that demonstrates how surface water generated by a proposed development will be managed safely and sustainably. Local Planning Authorities and Lead Local Flood Authorities often require a drainage strategy to assess whether a development can be serviced without increasing flood risk on-site or elsewhere.
Whether you're proposing a residential development, commercial scheme, agricultural building, or mixed-use project, a well-prepared drainage strategy can significantly improve the likelihood of planning approval.
-
A Drainage Strategy is commonly required as part of a planning application where a proposed development will create new impermeable surfaces, alter existing drainage arrangements, or generate additional surface water runoff and foul drainage.
Local Planning Authorities frequently request drainage strategies for:
New housing developments
Commercial and industrial developments
Extensions and redevelopment projects
Sites located within flood risk areas
Major and minor planning applications
Developments requiring Sustainable Drainage Systems (SuDS)
Greenfield and brownfield sites
Many planning authorities require drainage information at the application stage to demonstrate that drainage issues have been properly considered before planning permission can be granted.
-
A drainage strategy identifies suitable drainage features, discharge location(s), assesses existing drainage infrastructure and demonstrates compliance with national and local planning policies.
It is typically prepared by specialist drainage consultants and forms an important part of the planning application process.
-
The cost of a drainage strategy for a planning application depends on several factors, including site size, development type, planning requirements and the complexity of the proposed drainage solution.

-
The timescale for preparing a drainage strategy for a planning application varies depending on the complexity of the site, the information available and the scope of assessment required.
Simple developments can often be completed within a matter of days, while larger or complex strategies may take weeks.
Early engagement with a drainage consultant can help identify potential constraints at the outset, reducing the risk of planning delays and ensuring drainage requirements are addressed efficiently.
At Raincloud, we pride ourselves on delivering high-quality drainage strategies quickly and efficiently, helping clients meet planning submission deadlines and keep projects moving forward.
