Kai Tak Nullah


The Kai Tak Nullah is a nullah or watercourse that collects water from the rivers and streams flowing from the hills in northern New Kowloon. It empties into a narrow channel leading into the Kwun Tong Typhoon Shelter. Part of the nullah is covered by roads and other facilities.
The Kai Tak Nullah is about 2.4 km in length. It flows from Po Kong Village Road along Choi Hung Road, pass Tung Tau Estate and San Po Kong, into Kai Tak Development Area before discharging into the Victoria Harbour. It has an upstream and a midstream. The nullah is one of the major flood relief drainage channels in the East Kowloon area. The improvement work of Kai Tak Nullah has been overseen by the Civil Engineering and Development Department since March 2012, aiming to turn the nullah into an attractive green river corridor. It is anticipated to be fully completed before 2021.

History

Originally, the place of Kai Tak Nullah was a bay. During Japanese occupation, Kai Tak Airport was expanded through land reclamation. The extension of Fung Wong Kai Stream was named as Lung Tsun River龍津河.Lung Tsun River's original estuary is at the north of To Kwa Wan Road. But after the airport expansion work, the reclamation for runway blocked estuary and the river was redirected into today's route.
During New Territories new town development in 1970s, river become a nullah for Tai Po Sewage Treatment Works, The Shatin Sewage Treatment Works and illegal discharge pollutants. This results pollutants and heavy pollutants in water, which also causes smell issue. After the treatment work done by the Drainage Services Department, the Kai Tak Nullah has been significant improvement since 2000. Ardeidae is seen beside the nullah.

Proposal of covering nullahs

On January 2005, the Drainage Services Department announced plans for nullah-covering works for 16 nullahs, at the cost of 1.2 billion Hong Kong dollars. These included a plan to cover up part of the Kai Tak Nullahs along Choi Hung Road, starting in 2010 and finishing by 2014. The Traffic and Transport Committee of Wong Tai Sin District Council demanded a faster timetable, in order to launch the greening work and widen Choi Hung Road.
As the water quality improved, at the urging of the pro-Beijing political party Democratic Alliance for the Betterment and Progress, the Federation of Trade Unions, and environment concern group Conservancy Association, the Civil Engineering and Development Department launched a feasibility study on turning the nullah into Kai Tak River. They aim to turn it into a new river like the Cheonggyecheon in South Korea.
