Options for treating stormwater

Stormwater quality treatment must be undertaken under the State Environment Protection Policies, which are binding for all government agencies, private individuals and businesses conducting activities on private and public land.

The location of your treatment measures will determine how you maintain and operate your system. Decide whether you will adopt an outlet or a distributed approach to stormwater treatment.

There are a wide range of stormwater treatments and configurations. Do your research so you choose the right one.

A treatment train is a sequence of stormwater treatments, designed to meet the needs of a particular environment.

Constructed wetlands are a series of shallow, densely-planted, man-made ponds that help filter water through physical and biological processes. They provide a natural way to treat and remove pollutants from stormwater before it enters our creeks, rivers a

Gross pollutants traps are structures that use physical processes to trap solid waste such as litter and coarse sediment.

An infiltration trench is an excavation filled with porous material, which collects stormwater run-off.

Porous paving allows water to pass through it and filter back to the drains or into groundwater.

Raingardens are specially-designed garden beds that filter stormwater runoff from surrounding areas or stormwater pipes.

Rainwater tanks can reduce the harm to our waterways caused by too much stormwater.

Sediment basins are ponds with open water that capture coarse sediment and litter carried by stormwater.

Swales are linear, depressed channels that collect and transfer stormwater.
