#. Japao Tokyo Flod Tunnel 26.10.08

  1. 1. TOKYO FLOOD TUNNEL “ G - CANS PROJET” (SEWER SYSTEM) Pesquisa elaborada por: Prof. Ramon Armesto Mondelo [email_address]
  2. 2. G-CANS PROJECT The G-Cans Project is a massive project , begun 12 years ago, to build infrastructure for preventing overflow of the major rivers and waterways spidering the city (A serious problem for Tokyo during rainy-season and typhoon season). The underground waterway is the largest in the world and sports five 32m diameter, 65m deep concrete containment silos which are connected by 64 kilometers of tunnel sitting 50 meters beneath the surface. The whole system is powered by 14000 horsepower turbines which can pump 200 tons of water a second into the large outlying Edogawa river." This guy says "64 kms", but according to the info shown on the official site it's only 6,3 km. The project is located in the northern suburbs of Tokyo in Saitama prefecture. He doesn't mention a *HUGE* 177m long x 78m wide x 25m high main tank. http://www.g-cans.jp/facility/shikumi.html
