Sustainable Urban Drainage Systems - SuDS
SuDS: CPSA Proprietary Sustainable Urban Drainage Systems and Components
The use of sustainable urban drainage systems (SuDS) best management practices should be an integral part of any development’s surface water management strategy. This should provide a basis for replicating the response of a catchment and its surfaces by mimicking, to some extent, the behaviour of surface water on the developed site as if it had remained undeveloped.
Principles of Sustainable Urban Drainage Systems
- Controlling surface water quantity (reducing off-site flow rates).
- Improving surface water quality.
- Providing added amenity value to the development.
The successful implementation of a SuDS scheme should consider a combination of natural and proprietary techniques, complemented by traditional drainage methods, where appropriate. It is essential that planners, designers, installers and operators of SuDS drainage systems take into account the importance of whole life maintenance and the use of suitable components that deliver authentic sustainable drainage performance and longevity.
SuDS Management Train
The Sustainable Urban Drainage Systems philosophy is underpinned by the water “Management Train”. The Management Train applies SuDS Drainage techniques in series and is based on:
- Prevention; good housekeeping measures within the development.
- Source control; runoff managed as close as possible to where it originates as rain.
- Sub-catchments; division into small areas with different drainage characteristics and land use.
- Site Control; dealing with runoff within or local to the development.
- Regional Control; e.g. SuDS Drainage features within amenity space before final outfall.
The Management Train can be divided into the following processes:

CPSA members offer a wide variety of proprietary SuDS components and systems suitable for use within a sustainable drainage system. These are listed in the table below indicating their functions within the Management Train. For specific product information, please consult our members.
