Bangkok declares all 50 districts flood disaster areas

Bangkok Governor Chadchart Sittipunt has declared all 50 districts of the capital flood-disaster areas after heavy rain for a third consecutive day caused widespread flooding on Saturday, September 26.

The city-wide designation expands an earlier declaration covering three districts. It allows government agencies and local authorities to act more quickly and in a coordinated way within their legal powers to respond to flooding and assist residents.

Almost 300 millimetres of rain has fallen since Thursday afternoon, according to Chadchart. Rain has fallen almost continuously, flooding roads, swelling canals and sending water into homes and restaurants beside them.

Canals full as eastern Bangkok is hardest hit

Chadchart said eastern Bangkok had been worst affected and warned that more rain was forecast.

"The rain keeps falling and we are doing our best. We are trying to pump the water out, but the water in canals are full," he said on social media.

"The risk areas are those who live near canals. Every canal is now filled."

Further south-east in On Nut, AFP reporters saw people wading through knee-high water along a road and filling sandbags to take home.

Somkid Pheuk-ngam, 67, a vendor living near a canal north of central Bangkok, said the water had reached waist level.

"The water keeps coming in. It's hard to go out now. It's like at my waist level now," she said, adding that she had closed her shop for two days. Although flooding was common in her area, she said: "I think this time is worse than the 2011 flood."

Chadchart urged people with bedridden relatives who depend on life-saving medical equipment to consider a temporary stay in hospital. He also advised residents to move cars to higher ground.

Bangkok's public transport authority is offering free use of MRT train park-and-ride car parks for vehicle storage until October 2. The Bangkok Metropolitan Administration said it would continue monitoring rainfall and flooding closely while coordinating assistance across the city.

Wider flood risks remain

The Department of Disaster Prevention and Mitigation has warned that low pressure over eastern, north-eastern and central Thailand could bring risks of flash floods, forest runoff, mudslides and river overflow until Sunday.

Central Bangkok's roads seem wet but not flooded. In the north and north east of Bangkok, the problems begin around the Lad Prao junctions. But basically, as far as the current live road condition maps indicate, central Bangkok roads are green, with the flooded major roads and their sois out in the semi-inner outskirts and beyond. Hopefully they'll start to dry out by tomorrow afternoon.

Right, except the Tigers were already in the den.

Cost of these floods is going to be enormous . Vehicles, thousands of them, even tens of thousands written off, low lying businesses too in low lying Bangkok, its hard even imagining the costs involved, without taking into account of a repeat of it all next year. Abandon all hope

Yes it's bad - but not nearly as bad (on a macro scale) as the great floods of 2011.

Even centuries ago , when invading Burmese armies surged into Thailand and put the capitol Ayudhaya under seige , the Thais behind the walls prayed for an early monsoon knowing that the surrounding land would be inundated and that the Burmese would have to break camp and depart.

and then moved the capital to Bangkok which being in the middle of a swamp could not be reached by the Burmese war elephants.

Being flooded out is just one part of the crisis. Another is that water overflowing the sewer system, bringing up all that crud and whatever else. Sanitary hazard.

In 2011 when I chickened out and went to stay with a mate in Satahip I filled a balloon with water and jammed it into the downstairs toilet.

Had some lazada shipments due today, the courier company sent me a message they could not deliver to due force majeure.

I'll bet the insurance companies will be riding that BS excuse too!

Yeah, think about all those cars. If the insurance industry balks, Thai people already suffering from this bad economy and low incomes will be really screwed.

My understanding is that after 2011 most insurance companies removed flood damage from house insurance policies or limited it to 1000 baht - well that's what mine did........

Understood - I don't think compulsory covers it at all anyway does it?

If so going to be a lot of pain for many people as @ronnie50 said.

Ah yes, the 2011 floods... so extensive the Coke factory was knocked out for a bit.

I seem to recall a huge budget was allocated for flood prevention/diversion projects so wouldn't happen again.

Well, major portion of that went to factories etc which left little to spend on dikes, pumps, canals... and so it goes

Depends on where you are, I guess. I'm on Phutthamonthon Sai 3. Just at the top of the moobahn, Borom was elevated a meter or more to form a flood wall. Along the main road and down the village moobahn, new drainage pipes were put in during 2015. While my area of Bangkok has escaped being hit hard this time (as opposed to the almost three months of my house being flooded in 2011), it has still rained heavily and there is no standing water, no pooling, and absolutely no flooding.

I just checked my own (car) insurance from one of the biggest auto insurers.

The words flood, water damage, Act of God, natural or man made disaster - are absent. So maybe the insurance companies cannot get off so easily.

Yes, mine is Type 1 as well. Which I guess means 'comprehensive'.

See if the insurance industry is up to meet these costs, my take is they are not, would not be surprised if some go bust, regardless of which, price hikes in the future are going up considerably

Okay - this might be a simple Q to some. I admit I did study geology - for one semsester in high school... but.

How is it that, Bangkok, essentially a flat city with an altitude of around 0.1 metres, can have 30 cm of rain over two days and end up with some major streets flooded with water up to a person's chest (140 cm)? I understand that the ground is saturated so the rain cannot run off and I also get the fact that the klongs filled up and overflowed in some places. However, the klongs are normally a good 60 cm below the maximum (before the rain). So how else does 30 cm of rain become 140 cm in some places and not others? Just very slight differences in topography, and so the water finds the lowest nearby points and continues to collect and rise? Is that it? Or am I missing something? The 2011 floods were quite different as dam floodgates up country were opened - the Chao Phraya flowed over its banks - so partially a man made flood and not a good comparison.

The rainfall number is for the whole city area but that rainwater flows to wherever it can, especially off structures and onto roads, which cover less surface area than the whole city - the same volume of water then rises in level over that reduced area. Of course, the existing drainage network always struggles with heavy monsoon weather. Some area are better drained (or drainable) than others.

The klong system is much smaller than it used to be and those klongs near the river drain poorly if the river water level is also high. There are also spring tides now.

Thanks. Makes sense. And I guess the buildings on each side of the main road (like Petchaburi) act as 'river banks' containing the rising water.

Move and build your capital at the mouth of the largest river in the country, flowing down a massive 1000 long natural valley, being fed from the Issan Plateau to the North East and the north and west mountains, into a marshy flood basin, and guess what happens. Yes, of course there was a logical trading reason for it to be in that location in past history, but those reasons are now gone and the residents of Thailand's largest and most congested City must now live with the consequences.

Main roads, yes. Most of the offices, condos and hotels have raised ground floors.

just because they declare a public holiday does not mean employers should honor them.

I didn't say that, did I? However, I would say that the safety of all employees should be the prioroty.
