PHUKET:-- The major project to upgrade the drains that run under Bangla Rd in Patong, which has been under lockdown since April 3, have been installed with flaps on the drain grates in the hope to putting an end to the stench that has become a renowned aspect of walking along the famous street.

 

Patong Mayor Chalermluck Kebsup explained to The Phuket News’ Thai-language sister newspaper Khao Phuket that Patong Municipality is rushing to complete the project.

 

“We spent a budget of around B4.3 million on designing and installing the drains, as sometimes wastewater makes a bad smell along the drains, affecting Patong’s tourism image,” Mayor Chalermluck said today (June 25).

So they needed a hi-tech expensive solution with flaps under the drain covers that will hopefully work automatically.

Why don't they just have a water trap in each drain cover.

 

No reason for the flap to be "high-tech expensive".

 

A simple off-centre pivot rod (sitting on open topped pivots at the side of the drain) about 2/3rds of the way across the flap (which would match the full area of the drain) with a counter weight on the remaining 1/3 side of the flap, would allow the flap to open under the weight/flow of rainwater  and close when it stopped.

 

Flap positioned far enough below the grating such that the rising portion did not foul it.

 

Easily lifted, for clearance of blockages and sewer maintenance, by a rings on the top of the flap.

 

Can you find an image on the net of an "industrial sized" u-bend (toilet) trap, large enough to cope with torrential rainwater?

 

And consider the difficulty of trying to clear blockages in one.

Given the location of Bangla Road, where do you suppose that wastewater reeking of raw sewage discharges?

Not directly into the bay, more a sort of “leak”.

“Patong Municipality Mayor Chalermluck Kebsap said wastewater had leaked from the municipality’s wastewater treatment plant into the sea on February 6, because there was more sewage than the total capacity of the plant.”

Agreed,  nothing high-tech about these devices. Basic principle the same as a typical non-return valve. Mind you, at the quote given for the works I'm assuming the items were gold-plated.

And the missing addendum...

"Oh, and because not all of the city's sewers are connected to the treatment plant, there's always a bit of 'leakage' anyway. So there's that too."

in the hope to putting...

 

There is always hope that it works, never certainty. Great work !

Saw the work and it looks like that it is just as fantastic as on the beach road, with the grates either 10 cm abover or below the tarmac level but never at the same. Mai pen rai...

So instead of wasting 4.3mil on flaps of which probably only half made it to the actual project) why didn't they spend the money on expanding the sewerage treatment plant??? duh

Yes I mentioned similar in a thread named "Patong-The Wake" although when I saw them I thought that there was a gap between the grate top and the road, but this looks to have been filled in now.

 

I 'tested" these flaps and believe they are spring loaded, so what happens when the springs age/go rusty/lose tension? There had to be a better way (as described by "enoon") but TIT.

Sir, you surprise me.

 

“…what happens when…”

 

Simple; ‘Officials’ will visit the nearest branch of the Bank of BrownEnvelopii and appropriate another (almost) 5m Baht to sort out the, ahem, misunderstanding.

 

Where the network is combined foul/surface water, the foul water covers should ideally be sealed units (to control the smell caused by the stinky farangs) with trapped gullies situated in the road to collect the surface water which is then directed to the combined sewer.

Perhaps after a farking decade, they can install one at the entrance of walking street, pattaya beer garden, the epicentre of a high class family resort destination. But why, just what every tourist wants to smell while on holiday. Pure <deleted>????????????????????????????
