Pattaya – The Pattaya City Administration is planning to add more water drainage pipes and systems near Pattaya Walking Street in South Pattaya to solve persistent flooding problems in the area.

 

Pattaya City Deputy Mayor Pattana Boonsawat and staffers have been surveying and visiting the area in front of Walking Street over the past several days.

 

Deputy Mayor Pattana told The Pattaya News, “Mayor Sonthaya Khunplome has found that from the South Pattaya Intersection along the Chalerm Phrakiet 2 Road is an area of concern that receives a high amount of rainwater through drainage from the city and from Sukhumvit Road.”

 

“When Pattaya suffers from heavy storms and persistent rain, floodwater in this part of South Pattaya is unable to quickly flow into the sea.

As Travis Bickle said, "Someday a real rain will come and wash all this scum off the streets." But actually he loved the "scum" of Walking Streets, as do I.

I am just wondering if walking st can return to normal, I doubt it.  Probably takes another 5 years.

Wow; this must have taken a real meeting of superior minds to come up with a plan that should have been put in place several Decades ago.   I find street drainage here appalling for the most part with a lot of drains in the wrong places; rather like road markings !

More accurately it is dipping their fingers......

It always amazes me how Thai officialdom know intrinsically that corrupt money tends to take the path of least resistance, and yet fail to recognize that water does the same.

It won't, by that time they've fixed the drainage, so it won't be like it was before...

time to dig up the streets again

I remember that area about 20 years ago It looked messy and today i can see it still does.

So after the drainage pipes have been fitted kiss the beach goodbye every rainfall?

"Planning" is an awkward choice of words for reporting on Pattaya Infrastructure.

No matter how much work they do it will never drain how do you put in more pipes drain where is the water going to drain when it is high tide it just back up you will never win against the ocean!  These ideas are nothing but skimming off the top for the chief here one only has to go down to the beach and see after each major storm.  You can dig until the next century it will never happen in my life time.

It would probably be easier to pick up the city and move it than wait for them to get it right.

Hopefully it will at least get rid of the horrible sewer smell there, but doubt it’ll take care of the flooding.

Lawdy Lawdy - the secret's finally out!

[Andycoops]

A complete waste of time and money, except that going into the usual suspects pockets of course, which is why nothing ever works as it should to keep the gravy train running.

Sounds like the same plan they used on soi Khao Noi.

Hmm - it turns into a river every time it rains. Let's dig up the recently completely new street and add another (small, cheap) drain pipe on the other side of the road.

(Couple years later.....)

Hmm, it turns into a river every time it rains. Let's dig up the recently repaired street and add another (small, cheap) drain pipe in the middle of the street this time.

Along the worst stretch (where the "river" really gets going) there are now 3 sets of normal drains across the road as well as large storm grates.

But when you expect 10m³ of water to flow through 3m³ of pipes, it ain't going to work ! And it's not all due to the garbage plugging the pipes. Normally, the first big rain gets rid of most of the garbage (and plugs the grates). A few days later all that plastic has been shredded (by people driving over it) and fallen back into the lower end of the drains.
The next big rain washes most of that down to the pumping station and the grates get plugged with a lesser amount of "new" garbage.

By the time of the 4th/5th rain, there shouldn't be much in the way of garbage left in the drains, but they still back up because they are simply too small to handle the amount of water flowing into them.

The drainage channel behind the Batman building (that is supposed to drain all that water from the Suk/Pattaya Tai intersection) is actually 2 channels under the soi, each large enough to ride an ATV through. I think a guy 2m (6') tall could walk through them, wearing a hat, and not worry about scrapping his head on the top. 
Not sure where that channel goes to. (They finally finished whatever work they were doing on it and covered it over again just before the last big rain. Didn't help as the area around the Batman building turned into a meter deep lake again anyways.)

The drain pipe they are installing along the railway bypass appears to be about 1 1/2 meters (4 1/2') in diameter. They'd need two of those (at least) to handle the volume of water flowing down Khao Noi every time it rains. No doubt the same for Khao Talo as well.

The railway bypass should have a deep concrete channel running down the center of it, especially with the new highspeed rail line they are putting in. Getting rid of the runoff from Khao Noi and Khao Talo would greatly ease the amount of water flowing down to the Suk/Pattaya Tai intersection (and from there all the way down to the ocean).

My grandkids may see the day when they finally manage to get the situation under control. 

I guess that means I'd better get around to having kids soon, so they will have kids that might one day see an effective drainage system in place (either by aliens or more likely by our new Chinese overlords).

Khao Noi near the Mike Orchid Villa. You can see the original and second drainage systems. Those 2 pipes are draining water pretty much from the top of Khao Noi down to the bottom. 


This is further down Khao Noi from the above photo. You can see there are now 3 sets of drains spanning the road and a large "storm grate" as well.

Despite all that, the water will often be high enough to start going into the buildings on the left side of the photo.

More money for the boys, why let the gravy train dry up!
