Disaster strikes Shelah this week. Why cry a river when your house is already flooded? She tries to fix her feet to the heart of the issue, while watching her sofa float around the living room.
stormwater management Reply #1 on : Sat December 17, 2011, 05:56:44
London has been having similar flood problems, and we should learn from this experience. As most of the paving in London are impervious (like KL), stormwater could not seep down into the ground, and is forced to simply flow down into the concrete drains, which obviously have very limited capacity. Millions of fishes are killed as the River Thames are filled up with overflowing sewage systems. Even Heathrow airport was flooded with sludge when the sluice gate was jammed.
There has been a heated debate whether to install a £3.6 billion Thames Tideway Tunnel, or to control the stormwater nearer to the source through Sustainable Urban Drainage System (SUDS) like permeable paving, green roofs, street trees, rainwater harvesting, and downspout disconnections. Was there a similar debate before the decision to build the SMART tunnel?
This is why I am skeptical of the 'River of Life project'. We could make the riverfront as beautiful as it could be, and we could clean it up as much as we could, but all would be pointless if grey & waste water keeps on overflowing into the river, and into the streets & homes.
The SMART tunnel has proven not to be smart enough, so we should now move on to option 2: SUDS. Otherwise, our beloved KLIA might have to be turned into a sewer soon.
