Watch the Thames Water video documenting the repairs carried out to Island Barn Reservoir in 2017. Looking at the technology on how they identified the leaks, the new innovative process for the repairs, floating cranes on pontoons on the water, minimising the impact to the environment and how they plan to use this innovation at other reservoirs.
It's a great short video that shows just what happened whilst we watched it all happen around us. And, we sailed through out all of it… thanks TW
Also, here is a time lapse of the bridge being built to enable the piling machines and pontoons reach the water.
