How it works

Stormwater enters the attenuation tank via the inlet manhole, which incorporates a silt collection sump and a galvanised leaf collection basket. Water passes through the tank and enters the outlet manhole, which contains a vortex flow control device.

This flow control device regulates the release rate of the water from the tank, and in so doing, enables the tank to fill. As a result of water entering the tank at a greater rate than it can exit, the void space then fills with water. While the tank fills, air is vented from the tank back through at least 4 air vents, which double up as monitoring points and these can also be used to flush out the tank for routine maintenance.

The Inlet/Outlet pipe will act as a flushing channel. This perforated pipe is wrapped completely in High Flow Filtering Geotextile, which prevents silt entering the block area. As the tank continues to empty at a determinant rate, air re-enters the tank via the same air vent system. The roof of the completed tank must be lower than the lowest gully trap on site.
