How To Remove Silt From Pond? Causes & Methods

There are different methods to remove the silt from a pond. We carry out this type of work with different partners in your region (farmer, evacuation, …) To carry out a vacuum cleaning, we can vacuum the mud, sludge & silt and dry it in large cushions and directly gain volume.

Autumn & winter is the best period of year to remove some of the silt or sludge at the bottom of the pond.

Your approach would depend on the size of the pond and the amount of silt you need to extract.  If the pond is small you can first suspend the silt by using water or air pump flows to generate sufficient agitation to stir and suspend a fine silt (with also bacteria solutions).

Pond aeration helps ensure a fairly high level of oxygen in your pond. When the oxygen level is too low, it leads to increased fish mortality as well as the proliferation of silt and unwanted plants.

Aeration of the pond improves water quality and ensures the presence of beneficial bacteria. Fauna and flora can thus develop in optimal conditions.

Silt is often a sign of poor health for your pond. Mud is, however, an integral part of the life of your water point. Unfortunately, it is impossible to escape it. To ensure the sustainability of your pond and treat silt effectively, it is important to properly manage your pond. Various solutions exist to get rid of the silt.

The most expensive part of the cleaning process is the removal of the silt. In Europe, these silt have to be analyzed before being spread on fields or treated in sorting centers.

There are three main methods to remove silt :

Mechanical dredging

The first solution to removing the silt from your pond is cleaning. This is a quick and efficient process for removing much of the silt from the bottom of the pond with a digger. The mud is thus removed. The pond is then ballasted with all its nutrients and silt overnight.

This effective solution has several disadvantages. It can be very expensive and unfortunately not suitable for all ponds. Certain configurations make it impossible to clean the silt at the bottom of the pond. It should also be noted that this causes significant trauma for the pond, undermining its biological balance.

Bacterial mud help

Biodegradation makes it possible to degrade the silt in its pond efficiently thanks to a biological action. This is a natural way to remove silt from your pond.

Biodegradation involves adding additional bacteria and natural enzymes to the pond. This speeds up the process of decomposing organic matter and effectively manages the presence of nutrients in the silt. It improves the quality of the water in the pond.

Less expensive than setting up a cleaning solution, it must be part of a long-term process to be effective and to manage large volumes of silt.

Suction cleaning

We can also take care of the evacuation of your vases. We work with different techniques to treat the silting of your water body. The best solution is to contact us and send us some pictures of your water body on info@monbassin.com

  • Devastation with a 100% biological solution
  • Suction (suction cleaning of vases)

To reduce the amount of silt present at the bottom of your pond, it is possible to tackle the root of the problem and remove the plants present around the pond. Thanks to this, you reduce the amount of organic matter in contact with your pond. By extension, this will reduce the accumulation of silt and the appearance of undesirable aquatic plants

This solution has the advantage of not having to use any chemicals to treat the silt in its pond. In addition to being effective, it is very inexpensive and does not require a license. However, it takes a lot of work and does not bear fruit for several years.
