Contracting authority

Hong Kong's Eastern District floods when heavy rain hits. Streets are dense, surfaces don't absorb water, and the downstream drainage system is overloaded. A joint venture of Bouygues Travaux Publics and China Road and Bridge Corporation will build a 3.6km tunnel to catch stormwater before it reaches built-up areas and send it to the sea at Pak Sha Wan.
