This pack contains the SS300110 Silt Trap with Catchpit and Filter as well as cover and frame.The SS3006WSB Silt Sentinel Series Trap is a 300mm diameter chamber with catch pit and filter, designed to be put in line in front of a soakaway. These silt traps filter out sediment to help prevent the soakaway silting up thus ensuring longevity and an efficient soakaway system, as well as preventing flooding of the attenuation system.The Turtle Enviro soakaway silt traps are more technical and efficient than standard silt buckets as they work with a filter / mesh system to properly filter the water (however, as with regular silt traps, these also require regular cleaning out to avoid any blockages). The filter trap is very efficient silt and sand trap and will remove up to 99% of the silt and sand that would potentially enter the downstream drainage systems from surface areas.Designed specifically for sitting upstream of smaller modular / crate type attenuation systems, the silt sentinel series has a removable integral silt basket that sits just below the inlet pipe. The basket capacity is around 24kg, so can be lifted by one person for regular maintenance.The stocked chamber for a SS3006WSB is 600mm deep which can cope with the majority of installations; however, the height can be increased by adding a D822 300 diameter inspection chamber riser.andnbsp;We recommend using a silt trap with every soakaway installation to prevent build-up within the attenuation systems. Highly recommended in areas where there is the potential of high levels of silt and sand, eg. coastal and heavily landscaped hard standing areas.
