Packaged Plot Orifice Attenuation System - 3800 Litres with 110mm & 160mm Inlets
This plot attenuation system features a 300mm diameter silt blok, a pelican attenuation tank with a capacity of 4000 litres as well as an orifice chamber for the controlled discharge of water. This system is designed to reduce flooding as well as ensure that the stormwater is clean when it is discharged into a drain.
This is accomplished by having water that enters the drainage system pass through the siltblok, which contains a filter made from microporous plastic sections that will remove any sediment from the stormwater, allowing it to be cleaned before it goes through the rest of the system, which will prevent any blockages. As the attenuation tank fills up with stormwater, the orifice chamber will discharge it into a storm drain in a controlled manner so that flooding does not occur.
