EFFORTS to stop flooding in the northwest New Territories are being undermined by inadequate management of work on the West Rail project, a legislator claims. Yuen Long and Tin Shui Wai are still major flooding blackspots despite preventive measures over the years, according to figures by the Drainage Services Department. Rural leader Dr Tang Siu-tong, who is also a Hong Kong Progressive Alliance legislator, said the West Rail works were partly to blame, while the department should be held responsible for its lax monitoring. Last year the department received 466 complaints about flooding. About two-thirds were in the New Territories. Blackspots included Yuen Long, Kam Tin and Tin Shui Wai (97 reports); Tsuen Wan and Kwai Chung districts (66 reports); and North District (40 reports). In 1998 the department received 350 flooding complaints - about half were in the New Territories. A $7 billion infrastructure programme - which includes river training works, village flood protection schemes for low-lying settlements and drainage improvement works - is being implemented, according to the department. A report by the department presented to a Legco panel last week said the West Rail works had not directly caused the flood chaos last month, although it said flood levels in some areas might have been increased because of the works.
