In the New Territories, flooding is likely to remain a fact of life in rainy seasons, even with an adequate drainage system. Nature can always overwhelm the best laid schemes of men. But it has been doing so with such regularity in central Kowloon that, clearly, drastic action is needed to put a stop to what is becoming a common occurrence. Last month, an Ombudsman's report blamed illegally dumped construction waste for silting up drainage channels. This is a common practice, to which government officials often turn a blind eye, but that alone does not cause the mayhem which ensues with each red rainstorm. Earlier this year, a drainage department spokesman admitted the system could not cope with urban development. The real question is whether installing bigger drains over the next four years will finally solve the problem. Older parts of Kowloon are suffering the consequences of poor planning, as much as inadequate drainage. A system designed for the population density and conditions of 30 years ago now has to cope with development in Tai Kok Tsui and West Kowloon. Reclaimed land in that area is lower than the new area surrounding it. And it seems that there is insufficient means to allow floodwater to clear. If that is so, bigger drains are no answer. A process used successfully in Shenzhen may be more effective. There, pumps are installed to flush storm water out to sea before it can build up and cause the kind of flooding that plagues Kowloon. That solution should be considered now, before a four-year wait for relief ends in one more half-measure.
