Water Sensitive Urban DesignTreatment Measures

For examples of treatment measures, refer to case studies.

The removal of large pollutant matter such as urban litter is a primary treatment method for urban stormwater runoff.

Swales are linear depression of channels that provide for stormwater collection and conveyance.

An infiltration trench is a shallow, excavated trench filled with gravel or rock, into which run-off drains.

Stormwater retention with vegetation types reduces downstream flow velocities and subsequent drain sizes whilst facilitating secondary treatment.

Wetlands are a series of distinct cells that serve to filter and bio-remediate the stormwater.

Porous paving is an alternative to conventional impermeable pavements with many stormwater management benefits.

Rain gardens are designed for stormwater quality treatment and as an ornamental feature.

Rain water tanks can provide an opportunity to significantly reduce demand on potable (drinking water) supplies in certain areas of use.

Rooftop greening involves the establishment of vegetation to filter roof runoff and the capture and storage of that roof runoff for reuse.
