River Dredging — Silt Removal & Watercourse Maintenance in East Sussex & Kent
If your river, stream, or watercourse is silting up, flooding, or blocked with sediment and vegetation, river dredging is the solution. As river dredging contractors based in Battle, East Sussex, we carry out river dredging, silt removal, channel clearance, and watercourse maintenance for landowners, farmers, and estates across Kent and East Sussex. We own our own excavators and dredging equipment, so we can mobilise quickly and handle projects of any size.
Rivers and streams across the South East naturally accumulate silt, sediment, and debris over time. Heavy rainfall washes soil from fields, leaves fall and decompose, and vegetation grows and dies back — all contributing to a build-up of sediment that reduces channel capacity, causes flooding, and degrades the aquatic habitat. Regular river dredging and watercourse maintenance keeps channels clear, flowing, and functional.
Why Rivers Silt Up and Flood
Silt accumulation is the primary reason rivers and streams need dredging. Sediment from agricultural runoff, bank erosion, and organic matter settles in the channel bed, gradually raising the bed level and reducing the channel's capacity to carry water. As the bed rises, the river becomes shallower, flows more slowly, and floods more easily.
Vegetation growth compounds the problem. Aquatic weeds, reeds, and marginal plants colonise the silted bed and banks, further restricting flow and trapping more sediment. Over time, a river that once ran clear and deep can become a shallow, choked channel that floods after even moderate rainfall.
Blocked watercourses cause flooding on adjacent land — fields, gardens, and properties. For landowners and farmers, this means waterlogged fields, damaged crops, and flooded access. For estates and property owners, a flooding river can cause significant damage to land, buildings, and infrastructure.
Our River Dredging Services
We carry out river dredging and channel clearance using our own excavators — long-reach excavators for wider rivers, and standard excavators for smaller streams and ditches. We remove accumulated silt and sediment from the channel bed, restoring depth and flow capacity. The dredged material is handled responsibly — we're licensed waste carriers, and we can either spread it on adjacent land where suitable, or remove it for disposal.
We also carry out vegetation clearance — cutting and removing aquatic weeds, reeds, and marginal vegetation that restrict flow. We clear blockages such as fallen trees, debris, and accumulated leaf matter. For banks, we carry out reprofiling and erosion repair to stabilise the channel and prevent further siltation.
All our river dredging work is carried out with environmental sensitivity — we work to minimise disturbance to the aquatic habitat and time works to avoid spawning seasons and sensitive periods. We're based in Battle, East Sussex and cover all of Kent and East Sussex. Call us on 07376 622637 for a free river dredging quote.

Frequently Asked Questions
What is river dredging?
River dredging is the removal of accumulated silt and sediment from a river or stream channel bed to restore depth, flow capacity, and water quality. We use excavators to dredge the channel, remove the silt, and reinstate the bed. We carry out river dredging across Kent and East Sussex.
Do I need permission to dredge a river?
Many rivers and watercourses require consent from the Environment Agency or the Lead Local Flood Authority before dredging. We can advise on the consents required for your watercourse and carry out the work in accordance with the conditions. We handle river dredging across Kent and East Sussex.
How often should a river be dredged?
The frequency of dredging depends on the silt accumulation rate, the river's gradient, and the surrounding land use. Most rivers benefit from dredging every 5–10 years, but some need more frequent maintenance. We assess your watercourse and advise on the right maintenance schedule.
Can you dredge a small stream or ditch?
Yes. We dredge rivers, streams, and ditches of all sizes across Kent and East Sussex. For smaller watercourses, we use mini excavators that can work in restricted access. For larger rivers, we use long-reach excavators. Call 07376 622637 to discuss your watercourse.
