The StreamClean GPT consists of a circular chamber (plus risers if required) with a diversion channel:
The main factors which allow for sediment removal are:-
Stormwater from the main stormwater drainage system enters the diversion channel wherein a baffle diverts the stormwater to the storage chamber.
In the storage chamber the stormwater is forced into a vortex action and travels around the storage chamber. Oil & grease will rise to the surface where it is retained.
Pollutants and sediment within the stormwater are forced to the inside of the storage chamber. Sediment falls to the base of the GPT where it is retained. The cleansed stormwater leaves the storage chamber via the screen and outlet spigot, through the diversion channel and rejoins the main stormwater drainage system.
The StreamClean GPT unit is designed for use in non-pressure stormwater systems.
