Overview
The Tokyo Metropolitan Area Outer Underground Discharge Channel (G-Cans Project) is a 6.3 km underground tunnel with five giant silos that can absorb the equivalent of 25 Olympic swimming pools per minute, protecting 1 million homes from flooding. This programme visits the facility with a civil engineering expert, examines the drainage masterplan for Greater Tokyo, and draws lessons for rapid-urbanisation challenges in Gulf cities.
Program Objectives
- Understand the engineering principles and scale of urban underground drainage systems.
- Analyse Tokyo flood management governance and financing model.
- Apply lessons to flood risk management in rapidly urbanising cities.
