Dredging & Desilting
Specialist silt removal services for inland watercourse restoration projects
To ensure good management of all watercourses periodic dredging, desilting and maintenance should be carried out to promote a healthy eco-system.
Sediment and silt naturally build up on a daily basis within any canal, lake, stream, river or pond. This build-up of material can result in a number of issues including; decreased navigation of the waterways, restriction of floodwater draining from the surrounding land and urban areas and cause harm to the environment and wildlife. Furthermore, nutrients in silt cause weeds to grow and starve the water of oxygen. It can also be a health hazard, leading to blue-green algae and other contaminants.
P&D Environmental Ltd offers a wide range of dredging and desilting services for the removal of sediment from a variety of watercourses, including canals, rivers, lakes, ditches, moats and marina’s using a range of innovative methods to meet your project requirements. We offer a full project management service which covers:
Silt and sediment disposal
Specialist plant and equipment
Highly skilled operators
P&D Environmental utilises a wide range of methods for the removal of sediment ranging from small road transportable suction dredgers, floating excavators and barges through to long reach equipment operated from the bank.
How do you remove the sediment?
Once the material has been removed we can deal with the wet sludge in a number of different ways,
Our cutter suction dredge can pump material to settling lagoons or into de-watering bags
Our custom built de-watering plant processes the material into a dry format for cost effective disposal
The wet sludge can be removed from site for disposal
The dredged sediment can be spread in its wet format over agricultural land
Sediment can also be mixed with polymers to speed up the dewatering process and achieve a greater level of sediment removal. Polymer works by binding the fine partials together to make larger particles. The polymer is particularly successful when used with the dewatering bags with the polymer being introduced at the required rates as the material is pumped to the bags.
P&D Environmental Ltd can assist with any planning consents, waste exemption certificates, silt testing and consents for disposal, as well as liaise with farmers and landowners. We can also offer full ecology services through our working relationships with other companies as well as full site and hydrological surveys to assist with your project requirements.
