The Sewer is a sewer in Boulogne-Billancourt, and is the route that connects Kadic to the Factory. It is used by Team Lyoko to get there and back. The Sewer is accessed via the Park or the boiler room in Kadic or the backyard of the Hermitage and emerges on the bank of the Seine River. The Sewer itself has two strips of land on either side on which our heroes transport themselves, and in the middle is the water.Yumi, Odd, and Ulrich use skateboards to traverse the Sewer, whilst Jeremie and Aelita use scooters. The Sewer empties into the Seine, and is probably not used for waste products (although in Swarming Attack Odd and Jeremie were stated to stink after diving into the water to avoid a swarm of hornets.
