PUB Now Admits Stanford Canal Could Not Cope...

[Duckduck]

But it was BDA who issue the approval to divert the canal.....so are u saying one garment department went to slap another department butt?

 

im saying BCA n PUB shld take the blame if it really was the diverted canal fault. The canal is 10m wide & had been functioning well forever, then suddenly when 313 somerset is complete all the flooding occur...

Sawing off handles of windows so that inmates cannot escape in a high-security facility.

 

MRT trains become the expression of art by some jokers in a train depot TWICE.

 

Raising the road surface so that roads won't flood (& good luck to pedestrians & building owners).

 

Using cable ties to secure parts in a multi-billion transit system.

 

Pumping excess rainwater onto pedestrian walkways because a storm drain is unable to cope.

 

This first-world city is getting more and more interesting.

 

So when is the ministerial pay review going to be revealed to the public?

 

Can't wait...

[Blueray]

 

PUB installed so many monitoring devices and still dun know the canal was not able to cope ? either zzz and trying to act blur and hope nobody catch ...

It is incidents like this that continue to infuriate the citizens.

 

Despite what has happened these blokes still continue to be in their Lalaland & think we are idiots & treat us like one.

 

Really

It's all PUB baby as BCA as nothing to do with drainage.

isnt he the one promised "... Fix them!!..."

after that statement, many dare not mention his name coz dont want to kena fixed.....

 

I will say his name "you bang first" (translation from hokkien)

[Vulcann]

how complicated can it be? ---------- total up catchment areas/surfaces (and hence volume) which channel rain water into stanford canal and check if the size of the canal can take the total in the worst case scenario (high tides)....... it maybe involve tedious calculations, but it's not rocket science............ yet they screwed it up big time

 

It is not tedious to do calculation to determine the drain size.

 

Consultants of any development have to submit to the authorities the expected rainwater discharge into public drains together with the sewage flow in a separate piping system.

 

All these officials have to do is to compute the various existing & new developments together with the average rainfall directly into the drains to determine the desired drainage width & depth.

 

Orchard Rd shopping belt, having been developing at a breakneck speed during the last decade, should have an adverse effect in the Stamford Canal but strangely the authorities seem to be caught unawares.

 

With that many built-up surfaces & not many turfed areas traditionally used to drain-off excess effluent, the only way the rainwater can go is through perimeter drains & ultimately flow into storm drains such as the Stamford Canal.

 

Why no one picks this up is beyond me...

The destruction of large green space, especially around Orchard/Tanglin area maybe one of the causes.

 

I think this was highlighted before after last Jun/Jul flooding.

 

Anyone recall there used be a a greenary and hugh trees behind Orchard MRT when domestic workers used to gather during their weekend offs?

 

This pic taken from Shaw House before ION may give one a better idea how much of the water-absorbing zone was lost to ION since construction began in 2008.

 

Today, we see the immediate side-effect when short torrential storm hits the area. Forested or plantated soil is capable of absorbing large amount of water during short period, acting like a giant organic sponge. The capacity to absorb water means lesser storm water run-off, helping to avoid overloading the drainage system within short period.

 

So a combination of mild weather change and local reduction of green zone will have a compounding effect.

 

So my best guess to fix this, it will beyond what PUB is capable of addressing.

This will involve cross-study and coordination between agencies like NEA, National Parks, SLA etc.

Rumored is due to Marina Barrage will slow down the natural discharge rate of water compared to before before the barrage was build, but there is no concrete evidence that this is the cause

 

<FROM WIKIPEDIA>

Since completion of the Marina Barrage, there has been annual floodings in areas (e.g. Orchard Road shopping belt) which had been flood-free. There is a suspicion that the Barrage is slowing down the discharge rate of the storm water into the open sea.

 

This one can be deduced with commonsense.. you built something which partially block an opening.. you tell me whether the flowrate will increase or decrease?

Also, how was the canal diverted? a straight canal compared to a gently curving one compared to one with an "s" kink can have greatly different flow rates no?

Let's assume the current target water level at the Marina Barrage is 100 and we have flood.

They can always reduce it to 90 or even 80. This will increase the discharge rate. If the situation still the same, Marina Barrage is not the root cause.

 

And, the guys in Marina Barrage should start pumping water out into the sea once weather forecast heavy downpour is coming. Are they already doing this?

 

A lot of things they can do without spending our money....

I believe they are starting to observe at 90 today. Their standard practice is to apply the most expensive methods to impress themselves a lot of funds expended to to something (like malingering)

Again it is the same reason on a national level to go all out for economic gains that any side effect i.e. overcrowding at public areas, public transport unable to cope & in this instance rapid development without considering the downstream effect that these policy makers plan & execute without much thought.

 

Agree with you that in this case of drainage's incapacity to discharge water quick enough, it really is a cross-agency effort where all the related authorities, states agencies & stakeholders must coordinate their activites to tackle the problem.

 

At this stage though it is a matter of a little too late to consider counter-measures to so-called flash floods.

 

Looks like basement folks at Liat Towers have to continue put up with any further inconveniences of flash-floods until the first-world authorities get their acts together to permanently solve the flood problem.

Rather unfortunately though, the co-operation between the various governmental agencies has left a lot to be desired. PUB blames NEA, NEA blames SLA and so on and so forth. It is a game of passing the buck from one to another.

 

It is only until something serious happen such as the recent SMRT fiasco then all will start to sit up straight and pay attention.

And still dare to call themselves world-class govt drawing out-of-this-world salaries [shakehead]

 

Can't wait to see what Gerard & party comes out with on the ministerial pay review....

 

10% cut across the board?

Apparently, the committee has already submitted the report to LHL yesterday. As usual, everything is not final and will be subjected to amendments before approval by LHL himself.

 

Cronyism at its best!

They already declared 40% pay cut
