Silt Pumping – An Alternative To Dredging


Pumping Silt instead of Dredging

Removal of silt is essential when the breakdown of dead plant leaves and other organic material together with run-off from nearby fields creates a build-up on a lake, pond or rivers bed. This can have significant consequences for the water’s future, and for the life that exists inside of it.

Silt build-up will ultimately lead to a reduction in the depth of water meaning that the areas with higher silt levels will be at higher risk of flooding, biological decomposition and blockages resulting in boats and other crafts being unable to pass. Silt pumping a vital process within lake restoration and large pond cleaning strategies.

Silt will accumulate quickly when there are not enough trees, rocks, or other materials to prevent erosion. Agricultural soil is often swept away, and rivers and lakes in the vicinity can become clogged with silt. To survive, animals and plants which have evolved to live in moderately silty soil are forced to find a new habitat. River ecosystems endanger some species in rivers because they can not find their prey in silty water.

By using silt pumping as an alternative to dredging, we can undertake silt removal at a faster pace which is more environmentally friendly and kinder to the surrounding fauna and flora than other methods of silt dredging. When asked to dredge a lake or pond we will always consider the preferred possibility of pumping the silt over traditional dredging.  Methods of lake desilting have changed considerably over the years – Jex Plant always employ the latest time and money saving systems.


Things To Consider When Choosing A Silt Removal Solution Silt

Removal – How Is Silt Disposed Of?

One of the most significant issues to consider when removing silt is what to do with it once it’s been removed. Pond desilting creates a substantial amount of organic waste that needs to be professionally handled. One option would be to use on-site silt disposal solutions which include pumping the silt into dewatering bags, dredging it behind a permeable membrane and utilising flat land and bunding.

The silt can be used for on-site purposes and could be used as a fertiliser on farmland depending on its makeup. Removing the silt and disposing of it off-site can be an extremely costly alternative to on-site disposal and storage. Jex Plant UK Ltd can provide you with all the silt removal and silt disposal solutions on-site after providing you with a free survey. 

Silt Removal – Create Marginal Areas As A Way Of Disposing Of Silt 

Adding a permeable membrane around the edge of the water to create a new bank can be a great way to deposit silt across taken from the watercourse. If you do not have space on-site and if off-site disposal is not an option, this solution can provide you with a tremendous reusable opportunity for your silt. Once the silt has dried in its entirety, you can utilise the area by planting flowers, herbs, trees and bushes to give the waters edge a pleasing aesthetic. The membrane can be set and built in the correct shape and size at the necessary depth to suit the seeding and bank bottom.


Silt Removal – Off-Site Disposal

Removing silt and taking it to landfill is an expensive operation – This is due to the costs of waste disposal and taxes that will need to be paid on it. We always try to find solutions to keep the removed silt on-site in ways that can enable our customer to avoid the cost of disposing of the silt off-site. 

If it’s not possible and all avenues have been explored then we as a company would need to dewater the silt for it to be disposed of correctly as liquid waste can not be disposed of at a landfill. 

Off-Site Silt Removal – Using Dewatering Bags

Because liquid waste cannot be taken to landfill, dewatering bags, also known as silt removal bags, must be used to dewater the silt, turning it into a solid matter. Once the dewatering is complete, the fabric bags full of pure silt can be removed and taken to a landfill or the contents can be used for landscaping or on farmland. The dry matter makes for great compost. 

Silt Pumping – Use The Silt On Farmland

Silt can be pumped and then deposited on surrounding fields and land. It could also be piled up and left to dry out so that it can be used as compost or fresh soil for your fields, allowing great produce and vegetation to grow through. The removed silt could be used for; planting as topsoil, landscaping, manure for your fields and more. 

Silty soil is typically more fertile than other soil types, which means it is ideal for growing crops. Silt supports water retention and circulation of soil. Too much clay can make the soil too rigid for plants to grow. Agriculture has thrived in many parts of the world in river deltas, where silt deposits are plentiful, and along the riversides, where annual floods replenish silt. The Egyptian Nile River Delta is one example of an exceptionally fertile region where farmers have grown crops for thousands of years.
