Marine Testing Tank, Gosport, UK. One of the largest testing tanks in the world.
Under floor Pipes from Filtration plant room, 150mm (6”) Diameter.
The Pipe supplying filtered water to a large tank was suspected to be leaking. A full leak detection and camera survey revealed the leak to be directly under the tank, imbedded in 2 metres of concrete.
Digging to repair this fault was certainly not an option.
It was decided to completely line and upgrade the entire pipe network to future proof this valuable asset.
