Options for treating stormwater

Find out more about water sensitive urban design (WSUD) treatments and choose one or more that best suit your needs.

How to choose treatments

Selecting a treatment

Our six-step process and factors to consider so you choose the right treatment before starting work.

Stormwater quality objectives

Minimum requirements for meeting Clause 44 of the State Environment Protection Policy Victoria.

Outlet and distributed approaches

The location of your treatments determines how you maintain and operate them.

Treatment train

A sequence of multiple treatments maximise results by removing pollutants where pre-treatment is needed.

Types of treatments

Constructed wetlands

Shallow wetlands are a natural way to treat stormwater and can provide amenity for local communities.

Gross pollutant traps

These traps use physical processes to capture solid waste like litter and coarse sediment.

Infiltration trenches

An excavation filled with porous material that collects stormwater, which soaks into the surrounding soil.

Porous paving

A hard surface that reduces runoff volume by allowing water to pass through and soak into the ground.


Specially-designed garden beds using sandy soil and plants to filter runoff from surrounding areas or downpipes.

Rainwater tanks

Use stormwater in the toilet, laundry or garden to protect our waterways and reduce demand on drinking water.

Sediment basins

Open ponds that slow stormwater to capture coarse sediment and litter before it reaches our waterways.


Linear channels lined with grass or more densely vegetated and landscaped, which collect and transfer stormwater.
