The challenge
- Our popular waterways and canals can sometimes experience build-up of debris and silt at key locations, especially lock gates, sluices and weirs.
- An excessive build-up of silt and debris can lead to inoperable lock gates which become a hazard to navigation and stop leisure users enjoying the waterway.
- A wide variety of craft, from large wide beam vessels to narrowboats, utilise these canals daily, highlighting the importance for a quick response to any possible inspection, repair and maintenance (IRM).
- Visibility underwater for divers can be extremely limited, requiring experience and to use touch to successfully complete the IRM operations.
The solution
- JF Subtech divers were tasked at short notice to support with the IRM of three canal locations and arrived onsite.
- The team worked closely with the Canal & River Trust engineers, from planning to delivery, to ensure a smooth operation and high level of safety at all three sites
The results and benefits
- The canals at each location were successfully inspected or repaired at a fast pace by the experienced JF Subtech divers, ensuring they were operational again for canal and leisure users.
- Any blockages were safely removed and disposed of in an environmentally friendly manner to help reduce the risk to wildlife and the environment.
- We continue to be a close partner with the Canal & River Trust to maintain the tranquillity, accessibility and history of our waterways.
