MEGACITIES: PARIS PART 1 OF 3
Constructed in the nineteenth century, the sewers of Paris extend 2300 kilometres-the distance from Paris to Istanbul. This episode takes a look inside these vaulted tunnels where a million cubic metres of waste flows through the Parisian sewage system every day. The sewers are the digestive system of this mega city, bringing in life-giving fluids and carrying out waste.
It examines the dangers of what it takes to keep the system running smoothly. The episode follows Phillipe Bussignies, who has been working on the sewers for the past 25 year as he and his team lay out thousands of miles of fibre-optic cables through the sewer tunnels using a Cable Laying Robot.
Megacities explores this system beneath the Paris streets, where the inky blackness is broken only by the glow of fibre optic light. Paris plans to become the world's first fully connected wireless city.
