The Higashi Ogu Sewage Treatment Plant, located in Arakawa Ward, Tokyo, Japan is a facility designed to prevent eutrophication of the Tokyo Bay.
The core Nishi-Nippori District main pump building has six stories below ground with a reinforced concrete structure. The underground structure was completed through the design and construction of the pneumatic caisson method and has the world's largest plane area (4,837 sq m ).
A carefully thought-out plan, which carried out using advanced technical know-how at each of the design and construction stages, successfully realized in terms of both economic efficiency and high-accuracy, a first-of-its-kind supersize pneumatic caisson. The completion of this project will contribute greatly to future projects of large-scale deep underground structures.
