BANGKOK (NNT) - Bangkok authorities are gearing up for a sweeping overhaul of its drainage system in order to increase capacity as part of efforts to manage flooding in the capital.

 

The move follows a July meeting chaired by Bangkok Governor Chadchart Sittipunt, during which officials from various agencies and offices discussed potential water management solutions.

 

The Department of Drainage and Sewerage under the Bangkok Metropolitan Administration (BMA) is expecting precipitation coverage of around 60-80% throughout the city this month.

 

The Bangkok governor noted that the capital relies primarily on canals and tunnels to drain floodwater, with existing tunnel projects only designed to handle about 200 cubic meters of water per minute - just 10% of the outflow needed for effective drainage.

 

Chadchart has called for improved canal efficiency and dredging as well as work to clear debris and rubbish while expanding surface and groundwater storage capacity.

Why don't they call in some Dutch Engineers

They have been contending with flooding successfully for years...Or would there be some face loss if that happened

The Dutch engineers offered their help years ago but were bluntly told that Thailand knew what they were doing and could fix the problems. The standard <deleted> Thai reply to people offering to help.

Bangkok actually has a very good flood defence system in place. It is well protected against floods from ‘outside of the city’...  The issue is of course, money and litter...   the equipment needs maintenance, drains clog up with litter. 

 

 

But there is a greater facet at play - The actually amount of water falling within Bangkok in a very short period of time.

 

The average annual rain fall of Amsterdam is 850mm in a year. 

Bangkok received 132mm in one night (22-July) - drainage is completely different undertaking, the amount of water is almost an impossibility to handle when the city is on or slightly below sea level. 

 

Combined with a high tide, drainage to where ????

 

KL has an amazing scheme - The Smart Tunnel (Strom Management and Road Tunnel) which is closed in periods of high storm flow and the tunnel is used to take excess water before it is later pumped out once rains and storm run-off subside.

 

So... no, don’t ask the dutch.. Ask the Malaysians, they are next door, they have experience in dealing with volume of water which is not encountered Europe.

At least he's trying to resolve the issue that previous incumbents never did.

Yes , wait till the rainy season , THEN look to do something,

I mean every year they know what's going to happen, it

would make more sense to put money into infrastructure ,

which will improve people's lives, than buying more war

weapons ,

Normally i agree with your comments but this governor has just been elected. So these are his plans. So yes its late but he could not have made them earlier.

Fair enough , I suppose departments were just sitting on their

hands waiting for a new Governor to arrive and officially tell them

what needs doing.....
