Sustainable Urban Drainage

Systems

What is SUDS?A concept that makes environmental quality and people a

priority in drainage design, construction and maintenance.

The SUDS approach includes measures to prevent

pollution, reduce surface water runoff at source and provide

a range of physical structures designed to receive the

runoff.

Sustainable Urban Drainage

Systems Why applying SUDS?Urban creep---- We recognise that we need to manage

the amount of surface water entering our sewers, as well

as building more capacity where it is needed.

SUDS in UK

SUDS fall into three broad groups which

aim to:

1. Reduce the quantity of runoff from the

site (source control techniques);

2. Slow the velocity of runoff to allow

settlement filtering and infiltration

(permeable conveyance systems);

3. Provide passive treatment to collected

surface water before discharge into

groundwater or to a watercourse (end of

pipe systems).

SUDS in UK-Source Control

and Prevention TechniquesSource control and prevention techniques are designed to counter

increased discharge from developed sites, as close to the source as

possible and to minimise the volume of water discharged from the site.

This offers the benefits of reduced flood risk and improved water

quality. It helps to restore underground water resources and maintain

flows in surface watercourses during dry weather.

Examples: Green Roofs, Permeable

Pavements, Rainwater Harvesting,

Infiltration Trenches, Infiltration Basins.

SUDS in UK Permeable

Conveyance SystemsPermeable conveyance systems move runoff water slowly towards a

receiving watercourse allowing storage, filtering and some loss of runoff

water through evaporation and infiltration before it reaches the

discharge point. The main

types of permeable conveyance systems are underground systemssuch as filter drains (or French drains) and surface water swales.

Examples : Filter or French drains, swale

SUDS in UK Passive

Treatment SystemsPassive treatment systems use natural processes to remove and break

down pollutants from surface water runoff. Small scale systems such as

filter strips, can be designed into landscaped areas and are sited

upstream of other SUDS. Larger, endof pipesystems usually involve

storage of water in constructed ponds where natural purification

processes can be encouraged. Constructed wetlands and ponds also

provide the opportunity to improve wildlife habitat in urban areas.

Additionally, ponds can be made into amenity features for the local

community.

Examples :Filter Strips, Detention Basins,Retention Ponds, Wetlands.
