Flooding on Nathan Road in Mong Kok has mostly been resolved, thanks to the Tai Hang Tung Storage and Kai Tak Transfer Schemes, and local drainage improvement works.
Director of Drainage Services Raymond Cheung said today intensive urban development in Tai Hang Tung, Yau Yat Tsuen and Kowloon Tong has significantly increased stormwater flowing down to the Mong Kok drainage system, resulting in repeated flooding near Prince Edward MTR station during heavy rain.
"After much deliberation and detailed studies, we have developed an innovative method of combining a stormwater storage and a diversion scheme, namely the Tai Hang Tung Storage Scheme and Kai Tak Transfer Scheme," he said.

The storage scheme, the first large-scale underground stormwater storage plan in Hong Kong, is designed to intercept and temporarily store stormwater collected in the Tai Hang Tung area and the natural hillsides behind into a 100,000-cubic-metre tank under Tai Hang Tung Recreation Ground.
Meanwhile, the transfer scheme is the first drainage tunnel system in Hong Kong for intercepting and transferring stormwater flow from the decked nullah underneath Waterloo Road in Kowloon Tong, to the Kai Tak Nullah.
The department will continue outstanding works to improve the West Kowloon drainage system at a total cost of $4 billion.
