What we do

Silt Removal from Ponds and Lakes


Professional Lake & Pond Dredging Services

Jex Plant can be trusted in providing environmentally friendly Lake and large Pond Cleaning solutions. This is achieved through our primary water clearing processes of Dredging and Silt Pumping.

Lake Restoration – Dredging method

Silt dredging is an invasive, expensive & often environmentally unfriendly form of silt removal. Silt dredging usually involves heavy machinery, digging the silt up and then placing it in heavy trucks.

The silt is typically moved to another location however it can be kept on-site and reused, but we’ll get into more detail about this further down the page. If it’s not kept, then we move it to another location. Due to the amount of machinery and manpower required, the environmental impact of such operations can be huge. Silt dredging is a costly process even for small lakes and ponds.

Lake Restoration – Silt Pumping method

Silt pumping is a better solution to the traditional dredging method used in lake restoration. It removes the silt from your lake or pond using suction pumps. This method lifts the silt and transfers it to another location. Silt pumping is often the most effective method for clearing a large pond or lake of silt and sediment.

What is Lake Dredging?

Lake dredging involves the removal of materials that have built up within the lake itself and has resulted in there being limited capacity for the water that it holds. Clearing the bottom of the lake to restore water depth, enhance water quality, and promote a healthier aquatic environment.

What is Pond Dredging?

The same processes and machinery are recruited for Pond Dredging as clearing a larger waterbody like a lake or reservoir. It involves the removal of sediment, debris, and aquatic vegetation from the bottom of a pond to improve water quality, increase water depth, and maintain the ecosystem’s health.

Benefits of Removing Silt

Lake and Pond silt removal is important because it can decrease the possibility of flooding caused by build up in the lake. Clearing lakes of silt and sludge plays a vial role in maintaining and restoring the water quality. If the lake is used for boats, then dredging will reduce the chances of any leisure crafts becoming grounded and stranded in the centre.  and makes for a better environment for fish if fishing is permitted.

Dredging should be done to a lake when sediments have impacted the quality of the water and have inconvenienced recreational activities. Our company offers a cost-effective way to dredge lakes and remove sludge and silt in the process and does not harm the ecosystem.

What Happens To The Silt?

Should you keep silt or dispose of it? Our silt and sludge removal methods mean you can actually use your silt as fertiliser and spread it on your fields and land or store it, immediately after its been pumped.

Lake Silt Removal

The silt can be contained in a holding tank, or subject to chemical analysis can be spread on nearby land. This provides an added benefit in the form a nutrient-laden fertiliser for crops or other vegetation and saves on disposal fees. Lake sludge removal is the same, and as long as it goes through the pumping system, it will be concentrated enough to use.

Advantages of Silt Pumping

Removal of the silt is required when the degradation of dead plant leaves and other organic material along with run-off from nearby fields creates a build-up on a lake, pond, river beds and irrigation areas.

The main advantage of silt pumping, as opposed to silt dredging, is that it is quicker, requires less machinery, manpower and is more environmentally friendly. If the silt is not pumped, the water depth capacity will become limited, and this could lead to potential flooding, a build-up of pollution and then a release of decomposition odours.

How Much Does Silt Pumping Cost?

Because silt pumping requires less machinery, manpower and takes less time to accomplish, it is considerably cheaper than silt dredging. At JEX Plant Uk Ltd, we have the expertise, experience and equipment to help you save money when compared with the cost of traditional dredge and dump methods.

Is it a Lake or a Pond?

When does a pond become a lake? That’s a common question and one that’s reasonably hard to find an absolute definition. It can be somewhat subjective and can vary based on local conventions and regulations. If you’re dealing with a specific body of water and need to determine whether it’s a pond or a lake for legal or regulatory purposes, it’s best to consult the relevant local authorities or environmental agencies. They can provide specific definitions and guidance for your area. We have taken our definition from DEFRA (ref):

Ponds are usually smaller than 2 hectares (ha) in area. They can hold water all year or dry out for a period in the summer.


Lakes are larger than 2ha and are deep enough to have areas where sunlight cannot reach the bottom.

How Do We Desilt / Dredge A Lake?

We provide traditional methods of dredging from the start. We do this by first using an excavator with an extended arm in order to take the silt out the bottom of the river. The silt is then put into our macerated unit which chops up the weeds, removes the stones and turns the silt into a highly concentrated paste.

Once the silt has been turned into paste, the unit then pumps the solid material and can pump up to an 80% solid mass up to 800 meters away through pipes and can then be spread on to land as a fertiliser or into a container for you to spread at a later date.

The unique thing about our process is that our system uses high-pressure air and doesn’t use high volumes of water and is relatively mess-free.

The great thing with this type of system is that we can go from a large lake size pool to dredge right down to a garden-sized pond. Often people don’t realise that we are more than happy to go out and quote on smaller projects as well as larger projects. Larger projects may need surveying so that we can give accurate costings for our services.
