Sustainable Drainage Systems (SuDS) mimic natural drainage patterns and seek to manage rainfall close to where it falls.
The benefits of SuDS include:
- reducing the risk of flooding by slowing down surface water runoff and providing storage
- reducing surface water pollution by treating runoff through natural processes
- providing natural habitats for wildlife
- providing areas of amenity
Examples of SuDS include:
- water butts
- green roofs
- rainwater harvesting
- wetlands and reedbeds
- balancing ponds or detention basins.
How Sustainable Drainage Systems are designed
Early consideration of the movement of water is crucial to the success of SuDS and allows developers to maximise benefits.
It is important that SuDS features are appropriately designed, constructed and

If you are a developer, designer or consultant and want to know how to integrate SuDs into the master planning of small and large developments, our SuDS masterplanning document will complement guidance on SuDS design for different types of developments.
Our role in delivering SuDS
Lead local flood authorities were made a statutory consultee in respect of surface water for major development in 2015.
Medway Council Lead Local Flood Authority is committed to making Medway more
Through this process we advocate and audit the use of sustainable drainage systems for new developments in accordance with National Planning Policy Guidance and best practice industry guidance.
Statutory consultees have a duty to respond to statutory consultations within 21 days. Every year, performance reports are sent to the Ministry of Housing, Communities and Local Government (MHCLG).
