Silt Removal, Desilting & Dredging
Silt Removal, Desilting & Dredging
Silt removal is necessary when the breakdown of dead plant leaves and other organic material, along with runoff from surrounding fields, causes a buildup on the bed of a lake, pond or river. This can have serious consequences on the future of that water and the life there is within it.
The build-up of silt will lead to a reduction in water depth of the watercourse, increased risk of flooding, the release of nasty-smelling odours from the process of biological decomposition and potentially the loss of the watercourse.
We undertake silt removal, silt dredging and silt pumping works in ponds, lakes and streams, both natural and artificial. We are adept at minimising the impact of these works on the environment and the surrounding fauna and flora.

Silt Removal Solutions
The most significant problem to overcome with silt removal is what to do with the material. On-site solutions are to pump it into de-watering bags, dredge it behind a permeable membrane, utilise flat land and bunding. The removal of silt off-site can be a very expensive alternative. Aquatic Solutions can provide you with all the solutions for silt removal on-site after a free survey.
De-silting Using A Nicospan Membrane
Installing a permeable membrane around the water’s edge to create a new bank can be a way of depositing silt where there is little space around the watercourse. The silt can be dredged behind the membrane with the clamshell bucket attached to the Truxor. The silt is left behind as the water separates through the membrane.
Once the area has been filled and it has begun to dry, planting the area with marginal plants gives a new, aesthetically pleasing border to the water’s edge. The membrane can be set at the required depth to match the desired planting and bank edge and designed in the desired shape and size.
Silt Pumping Using De-Watering & Silt Bags
De-watering bags need to be placed on flat land to prevent any movement of the bags. The silt is pumped into the bags, and then they are left to de-water, and you are left with a fabric bag full of pure silt. These bags can be opened, and the silt can be reused on-site for any landscaping needs. As the silt is made up of decaying organic matter, it makes an ideal compost for planting in.
Silt Pumping or Silt Dredging Over Flat Land
The silt can be removed from the water through silt pumping or silt dredging and deposited 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. The silt could be stockpiled behind a temporary bund to prevent run off, which would allow for removal from the bund once the material has dried, or it could be spread out evenly behind the bund. Future uses of the dried out silt, if left on site, are: as a top soil to even out the land, landscaping, planting, beds or manure.
