Pattaya, a well-known resort city in Thailand, is taking a significant step to tackle its perennial flooding problem. The city is constructing a new drainage tunnel, aiming to ease the disturbances caused by persistent rains.

 

The flooding issue in Pattaya has been an ongoing challenge, particularly during the rainy season from May to October. The city's geographical location in a low-lying area exacerbates the problem, with water often overflowing from nearby reservoirs like Nong Pla Lai and Huay Yai.

 

Key areas such as Sukhumvit Road and Sai Sam Road are frequently affected, impacting both residents and tourists.

 

To address the problem, authorities have initiated the construction of a two-metre diameter drainage tunnel. This ambitious project is designed to divert floodwaters from the city's urban areas directly to the Na Kluea canal, which subsequently channels water to the sea in Bang Lamung district of Chon Buri province.

 

Pattaya's Deputy Mayor, Manote Nongyai, expressed optimism about the potential impact of the tunnel. He anticipates that the project, once complete, will significantly reduce flooding in some of the most affected areas.

 

However, the project experienced delays due to necessary route adjustments, prompted by the upcoming construction of a high-speed railway.

 

Despite these setbacks, city officials are committed to seeing the tunnel operational by early next year, ideally before the onset of the wet season.

 

The success of this project is crucial for Pattaya's future, as flooding not only disrupts daily life but also affects tourism—a significant contributor to the city's economy.

 

As the construction progresses, both residents and local businesses are hopeful that this tunnel will provide a long-term solution to one of Pattaya's most pressing issues, reported Bangkok Post.

2 meters  will be 3/4 full of rubbish and construction material before its even finished.. an "ambitious" project would be at least a 10 meter tunnel.

Yet another "drainage" pipe

Such negativity....

[ikke1959]

In most western countries they have something similar as Thailand has now invented it is called sewerage.....

[Ralf001]

where are they building the tunnel ?

You beat me to it. 2 meters is nothing especially when it is clogged with plastic 

[Emdog]

They have been at site next to my condo for a couple of years. Used to be large wooded area, which was clear cut and small road from 2nd in Jomtien to Thepprasit. What once was woodlands now seems to be a wetlands. Maybe you can see extent of vegetation that has grown since they started to see the swiftness of this project.

A tunnel like they are doing everywhere throughout Pattaya square or round slightly larger so one can drive a mini cooper?

Bullet train has nothing to do with any delay it wont come for years and years. The runoff from East is do to zero infracture drainage to these so call reserves nothing but holes. As we know water runs down hill these drums just hold more water below surface so people dont see.

Take Sukhumvit. From Thappasit to Pattaya Tai water runs downhill, north from the tunnel to Tai, runs downhill all in the middle a ditch at the end everything drains throught a 1 meter cement drain that drain goes down Tai all the way to beach road and WS, in the end drain at beach are too small along with water rushing down Thappaya to south end of WS. Reason road collaspe sinkholes everywhere.

Instead of patch work which produce yearly budget so Mayor can skim off have a master plan with other surrounding district to solve the problem but of course that ends much of the brown envelopes.

 

If they have the slightess clue bullet train need to start digging put the current tracks under ground at these location Choppawthi, Soi Siam, Khao Noi, Khao Talo, the bottle neck are already massive it id going to be even worse.

Me neither. By Huay Yai I assume they mean the Huay Chak Nok reservoir. That one hasn't been full since before the pandemic, and is currently only around half-full at a guess.

Poor use of words, these are overflowing it is overflowing from the inadequate drains in place no different in town too small so water just run down the roads toward the tracks then Sukhumvit.all one has to do heavy rain stand bottom of Khao Noi or Tala watch the garbage white water, if I was younger I get a canoe and take a wild ridethen thete are no real engineers all family nepotism keep the bandaid system is money in the bank.

Like kicking the can down toe road, the water will just flood somewhere else.

Anything like this?

If the roads remained flooded, it stops the boy racers from being a pest.

A "tunnel" to channel water from South Pattaya all the way north to Na Kluea so it can drain into the ocean ?
(Never mind the environmental aspect of flushing all the crap in the drains straight into the ocean.)

The only place they could construct such a tunnel is under one of the North/South streets (# 2 or # 3 road basically) or under the highway itself.
Can't even go down the center of the highway because you hit the "Center Road" tunnel and then at North Pattaya Road you have the Highway 7 overpass.

A couple years ago the city tried to alleviate the Sukhumvit/South Pattaya Road intersection flooding by installing a pump (by the north corner of the Esso station) and enlarging the drainage channel leading from the highway down the little alleyway that runs on the south side of the Batman building.

I recall seeing the massive open hole in the ground where they'd started the work, got as far as the little soi that runs from the Batman building up to South Pattaya Road and then stopped.

I marvelled at the size of the concrete "drain" channels. Two of them, side by side.

Each was wide enough you could have ridden a mid-sized ATV down them with no problem and anyone under 5'10" tall could have probably walked down them without bumping their head.

Took them a few months to finally come back and cover those channels over, install new storm drains and lay the new road on top.
But I never saw them extend that drain any further past that point.

And every time it rains, that intersection still floods - and soi Batman (the whole area around the Batman building) turns into a lake over 1 meter deep. 

It's the same thing on Khao Noi.

The first time I visited someone on Khao Noi (2009 maybe ?) the road had been completely torn up so they could install a new drainage system. Then they covered it over and for awhile it was a very nice, very smooth road.

And, naturally, a couple years later it was partially torn up so they could install and new, larger, drainage system, new storm grates at the bottom end and the "holding pond/pumping station" a few meters down the railway bypass.

I assumed that was a part of a project to protect the new railway bed from being washed out every time it rained. (Remember when they set down that new railbed years ago and brought in all those concrete railway ties that have been stacked by the rail station for (5 ?) years or so.)

Khao Noi now - if you can see the road through all the ad-hoc "repair" jobs from everyone and their dog digging up the street to put in a new drain pipe or something and then doing a craptastic job of filling in the hole and paving/cementing over it - has 3 separate drainage systems running down the road from just below The Chilled shopping mall to the railway bypass.

And every time it rains, from the Mike Orchard Villa housing compound down to the bypass, it turns into a raging white-water river.

And I don't think I've ever heard anyone, ever, blame flooding on those reservoirs - on the other side of the high ground east of the city - overflowing.

But hey, a tunnel sounds better than their previous plan to pump all the storm runoff from the sewers straight back into those same reservoirs, flooding them will all manner of toxic contaminates and who knows what else that people routinely throw down the drains.

On the top of a hill, works every time

[wombat]

Didn't they just do that?

[wombat]

Musk has a tunnel borer...1 million US per mile so I believe

[ChrisY1]

Clever....Pattaya is about 2 foot above sea level...well maybe a bit more......so the tunnel will be mostly below sea level.....then it'll need massive pumps to pump it back into the sea and then it'll flow into the tunnel again!

Yep probably straight into the sea where they dump all the rest of their 💩

[p414]

Chak nok lake [ Huay Yai ?]  is being filled and villages built where there was once year round water.

There is not much of the lake left now.

Yes but it will be capable of discharging over 22cm per minute

Well if Pattaya needs a pump, in "my"country, they built the biggest pump in the world.

Even a second and a third one, all the same.

Doing 50000 ltr/SEC ! horsepower of 5,364 ! lights will go out in Pattaya

https://fairbanksnijhuis.pentair.com/en/news/new-super-pump-for-ijmuiden-pumping-station

7. The Largest Pump in Operation Can Fill your Swimming Pool in 1.5 Seconds

The world’s largest pump was custom built by Pentair for the pumping station Ijmuiden in the Netherlands.  Roughly 1/3 of the Netherlands is below sea level, with the lowest point being 20ft below sea level.  Because of the landscape they are at high-risk for flooding in the region.  This pump is part of the largest pumping station in Europe which helps control water levels feeding in from the North Sea.

To give an idea of its scale and power, the pump has a capacity of 60,000 liters/second, and requires 5,364 horsepower to operate at this level.  It could fill your backyard swimming pool in 1.5 seconds, and an Olympic-sized pool in less than a minute.

So your advice is to put the high speed rail below sea level in a wetlands zone?

 

Ah, now I understand.  Chinese construction of high speed submarines.

Incorrect!

This story is reference about Pattaya!

I specifically reference to you a number of locations these locations are extremely heavy with traffic throughout the day due to one lane in each direction crossing the current railroad tracks which several times a day the train comes through traffic comes to a stop.

These intersection during morning and evening hours come to a standstill cause drivers dont know or been taught proper rightvaway and a simple stop sign.

There is no wetland from north to south along this road called

Railroad bypass the train travels slightly on a upgrade above ground they have already laid dirt gravel for the so call bullet train it will run nect to the train currently.

As it heads towards Soi Nerpludwan it goes under this Soi there is a bridge vehicle travel over the trains goes under!

The major intersection I mentioned the same should be done to these intersection I noted. When the train comes the closure will be more frequent a major accident is going to happen with the volume of vehicles crossing. If you know the area travel on the bypass one can see easily done.

Currently between these intersections they run 1-2 KM, because the train runs above ground in between there are zero way even bike to cross to the other side it forces every vehicles to travel KM out of their destination just to turn around.

By digging a bit lower at these intersections as they have done at Nernpludwan building wider bridges adding additional bridges along the bypass so vehicles could turn around instead of sending everyone to one intersection causing massive bottlenecks. 

There is no medical facilities east of Pattaya, medical emergency vehicles all from the otherside West of Pattaya. 

Your quick sarcastic reference to wetland and so call submarines just shows your ignorance to the area, problem, and greater population on the Eastern side that must travel across these tracks daily adding the bullet train to above with the railroad will add to the nightmare.

Seriously?

They're running high speed rail thru an urban area at ground level?

That figures.

A few Years back  they laid the gravel already  to allow to settle.
