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.

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.
