SMART tunnel – Clean up

April 2, 2008

Short blog entry today.

SMART is an acronym for Stormwater Management and Road Tunnel, a project under the Federal Government initiated to alleviate the flooding problem in the city centre of Kuala Lumpur.” It was featured on the National Geographic Channel.

The main touted feature of the SMART tunnel is that it is a dual use tunnel. In normal mode, it’s a road tunnel. If there is a need to divert water away from Kuala Lumpur to prevent flooding, then the tunnel gets converted to a big stormwater tunnel. When the situation gets better, its converted back to a road tunnel. 

My question is: how do they clean up the mud and gunk that is carried into the tunnel with the stormwaters prior to putting it into road tunnel mode? Is it a manual job, or is automated?
