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

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.
