The Sewerage Bureau is working to provide easy-to-understand information about the rarely seen mechanisms and roles of sewerage systems, as well as the policies the Bureau is promoting. This autumn, during the tourist season, we will be holding a “Tokyo Sewerage Infrastructure Tour,” which will take you around sewerage facilities in the wards and Tama area.
