Silt Pumping and Dredging
Silt Pumping and Dredging
The build-up of silt within a lake, pond or river can have serious consequences on the future of that water and any life there is, for example fish and other organisms.
We have two types of silt pump that can be used for different types of silt materials and density's. With the use of our excavator arm we can loosen any harder material on the water bed and then follow up with a silt pump to remove the loosened material from the water.
Ways of Disposing of Silt;
- De-Watering Bags or Silt Bags
- Spreading over flat land
- Creating a bund to let the material build up and allowing water to drain out
- Piling up the silt for redistribution
- Removal from site
Future uses of the dried out silt if left on site;
- Gardening as a top soil
- To even out land
- Landscaping
- Planting Beds
Disposal Of Silt
Spreading Over Flat Land
The silt can be removed from the water and disposed on land in the close vicinity. It can either be spread evenly over the land and left to allow the vegetation to grow back through, piled up behind a temporary bund to allow removal to different parts of the site once the material has dried or left spread out evenly behind the bund, which is just used to prevent any silt escaping onto sloped areas.
De-Watering or Silt Bags
To be able to use de-watering bags, they are required to be placed on flat land to prevent any movement of the bags. Once the silt has been pumped into the bags they are allowed to de-water and leave a fabric bag full of pure silt. Once dried these bags can be opened and used for any landscaping needs or all the dried material could be removed from site.
Removal From Site
When the silt is removed from the water it can be instantly transported off site to another location. This is an option when there is not sufficient land to pump the silt onto or land where silt bags can sit and de-water. The silt would be piled up or pumped straight into the desired transport and then taken to the desired location.
