The Major Projects Group site team put open drums under the drain valves to check if any residual material still remained. After all residual material had been removed from the pipes, a 35t excavator with 3rd member shear attachment cut the pipework into truck length pieces and loaded those onto trucks for disposal on the designated lay-down area.

Steam cleaners used a lance to clean the internals of the tanks, and the site team pumped out the remaining liquid waste into an In-Vessel Composter (IVC), so it could be transported into the coal tar storage vessel. Once the insides of every tank were cleaned, Major Projects Group’s excavator exposed the tanks and hammered the roof and side of the tanks.

A sample analysis of the concrete tank bases and of the soil under the tanks came back negative from all contaminations leading the site team to proceed with the demolition of the tank bases.

The Major Projects site team dismantled all pipework and associated infrastructure ahead of schedule and without any incidents.
