Preparations Underway for Canning Silt Removal Project
Work to remove around 14,000 tonnes of silt from Canning Half Tide Dock in Liverpool is due to start next week, ensuring the vital amenity is accessible for the many deep-drafted vessels and international boating events that use the city’s docks.
The Canal and River Trust, the charity that cares for Liverpool South Docks, said in their latest release that they have been carefully planning the £1 million project for the last 18 months, working with agencies and landowners including Marine Management Organisation and Peel Ports.
Silt has been building up in the dock, coming in from the River Mersey through the lock gates, since the last time it was dredged in the 1990s and is now several meters thick.
The trust plans to remove silt from across the whole area of the dock to increase the water depth to around 7 meters.
The material will be pumped back into the River Mersey, with the set up ensuring that the rate and particle suspension will have minimal impact on the existing concentration and flows.
According to the official release, the work is expected to take around six weeks.
