Silt Removal Solutions

Aquatic Solutions installing Nicospan fencing for silt recyclingUndertaking silt removal from any large body of water is a major project and one of the main questions we are often asked is “what do we do with the silt once it has been removed from the watercourse?”

Here at Aquatic Solutions we use our Truxor amphibious vehicle to dredge and remove the silt and we also have some innovative solutions for recycling the removed material.

Our silt removal methods offer cost savings and can provide an environmentally friendly option as the need for a fleet of vehicles to remove the silt from site can be avoided.


Option 1: Use Nicospan to create new banks

Nicospan is a permeable membrane used to create a “fence” around the perimeter of a body of water. It’s installed with wooden stakes driven into the watercourse bed at regular intervals, and the height of the fence sits just above the water level, as shown in the picture above.  The fence can be shaped to follow the existing banks, or to re-shape a lake or large pond.

The silt is dredged from the bed of the watercourse by our Truxor amphibious vehicle using a clamshell attachment (as seen in this video) and deposited behind the fence. The porous Nicospan allows water to flow out but retains the silt, creating new banks, packed with nutrient rich silt.The banks can then be filled with aquatic marginal plants providing an aesthetically pleasing border which will also attract wildlife.See our guide Aquatic Marginals for a wide range of suitable plants that we can install on the newly created banks.

This silt removal method has two main advantages – it acts as a silt receptor when there is limited space for storing removed silt and is a great way of re-profiling banks or creating new bank lines.

Nicospan is also a highly effective solution to repairing a leak in a pond or lake bank.


Option 2: Silt Bags or De-Watering Bags

Porous silt bagSilt Bags or De-Watering Bags are made from a permeable membrane into which silt can be pumped on site. The material allows the water to flow out, but filters and retains the denser particles of silt (anything larger than 64microns).

The silt is pumped into the bags using the Truxor amphibious machine and a silt pumping attachment through a series of pipes. The standard size of bag is 45m³, though we manufacture our own which means they can be made to size to suit the area on which they are to be sited.

Once the wet silt material has been pumped into the bag, the pressure created helps to separate the clean water from the silt. After the de-watering process the bags can be cut open and the silt  re-used for landscaping, put back into the land or, if necessary, removed from site. The silt removed from the water is very nutrient rich and provides an excellent planting medium.

We utilise Google Earth or you can attach pictures (below) of the area to help discuss any project in more clarity and detail.

All of our quotations  are provided free of charge and in the case of larger jobs we would undertake a site survey.
