Our Non-Woven Polypropylene Geotextile Dewatering Bags have been designed to collect harmful sediments from dirty water pumped out of excavation works which pollute the surrounding environment – this includes foundations, waterways, lakes, pipeline construction, water, sewer and utility trenches.
Snelst mogelijke bezorgtijd: Snelst mogelijke bezorgtijd: Tot 5 werkdagen
Features & Benefits:
- Collects harmful sediment before it can enter the watercourse
- Cost-effective solution
- Lightweight, compact and easy to store
- Only requires small working area
- 180 Micron pore size
Guidelines:
Position your Dewatering Bag on a slope so incoming water flows downhill through the bag and install Silt Fencing downslope of the bags to control any potential run-off pollution.
The bag is fitted with a collar that fits around delivery hoses or connectors – you can strap the neck of the Dewatering Bag tightly to the discharge hose using the attached tying cord.
If the filled bags are to be lifted for disposal then you can place lifting straps under the bag prior to pumping or you can roll the bags into a digger bucket. The Bag is full when it can no longer filter sediment or pass water at a reasonable rate. Once finished, the bag must be disposed of by the site engineer – bags are normally allowed to dry in place then either cut open, spread and landscape on site or bags removed and disposed of.

According to the Environment Agency Pollution Prevention Guidelines PPG6 – you are required to remove the majority of suspended solids including gravel, sand and silt from site water before being discharged into a drain, sewer or watercourse. If silty water has not been treated upon leaving a site and the correct pollution control measures are not taken, it is a finable offence.
Poor management of silt and silty water is a major cause of serious pollution incidents from construction sites. Silt Water can kill aquatic life and reduce water quality by causing flooding by blocking culverts and channels. Silt Water must not be discharged to a drain or watercourse without prior treatment to remove suspended solids. During your project, if you will be generating silty water it must be treated properly before discharge via lagoons, settlement tanks, silt traps or grassy areas that slow water and allow solids to settle.
Permission must be granted from your local sewerage provider if you are intending to discharge settled water to the foul sewer because this will be regarded as trade effluent.
