The Environment Agency (EA) states that site water must not be discharged off construction sites without control as this water can kill aquatic life and damage river beds and banks.
The Sediment filter sack is a filtration system, accepted by the EA, that controls flows and cleanses water of silt and sediment and can detect the presence of hydrocarbons. With a robust casing, nylon lifting straps and a 20kgs capture weight, it enables the simple and safe disposal of silt by one person. Most effective when used with 50mm (2”) to 80mm (3”) pumps, e.g. 1phase submersibles, small 3phase submersibles and most engine driven pumps.
