Marina Barrage</TD></TR><TR><TD> </TD><TD class=update> </TD></TR><TR><TD> </TD><TD></TD></TR></TBODY></TABLE>

SINGAPORE: Recent flash floods have prompted Singaporeans to question if the Marina Barrage is doing its job.

At a briefing Tuesday, national water agency PUB explained it has done so - citing Saturday's downpour as an example.

The intensity of Saturday's early morning rain caught everyone off-guard.

=> everyone = FAPee Dogs?

When the two-hour storm ended, more rain had fallen than what the whole of July normally sees.

It was the third time in a month that severe rainfall had caused flash floods in parts of the island.

PUB data shows that despite the rising water level, the volume was well within the reservoir's capacity.

At 5.30am, the flood gates were activated.

=> But it started raining much earlier than that, right?

By then, rain had been pouring for an hour.

=> There you go! Why the delay???

On the other side of the Barrage, the tide was also falling, and by 6am it was below the water level in the reservoir.

All eight gates were then fully opened to let excess water out.

The decision to drain water out of the reservoir, and how much to drain away, depends on several factors. These include how fast water level in the reservoir is rising, and if the level remains within an acceptable range. PUB says it also has to ensure that there is enough water in the reservoir to meet Singapore's drinking needs.

=> In other words, worse cum to worse, PUB will cause flooding to ensure min. water level in the reservoir! And that's after yaya and telling Msia that Peesai doesn't need its water!
Tan Nguan Sen, director of Catchment & Waterways, PUB, said: "The Marina reservoir was built for two main functions. One is to act as storage for fresh water, and the other one is for flood control purposes. For flood control purposes we want to keep the reservoir as low as possible, whereas as a storage for fresh water we want to keep it as high as possible."

PUB says if the level in the reservoir exceeded its upper limit, water will be drained out, either by operating the floodgates or the pumps.

But the Barrage may not release water every time it rains.

Mr Tan said: "Unless it is very sudden heavy rain, and we see that the water level is rising very much faster, we will as an added precaution release the water. We'll only release the water up till the lowest operating level that we have."

He also said the Barrage helped prevent severe flooding in the immediate areas downtown, though not in places further upstream, like Orchard Road.

obviously after all these incident, they should have realised that the upper limit should be readjusted.

are they plain stupid or dumb.

those limits are merely a guidelines as a tools. it should not be a redtape that causes all these unnecessary problem

toolanliao · Jul 20, 2010

only floodgate they open fast is the FT floodgate! :mad:

vamjok · Jul 20, 2010

what if the lower limit that was set by the american company was not suited for local weather?

if this incident happens in japan, the minister incharged would have commit harikiri

HTOLAS · Jul 21, 2010

I noticed the following during all three floods:

the water rose very fast, about 50cm in 30 minutes;
the water then stayed stagnant for between one (16 Jun) to nearly two hours (17 Jul) even though heavy rain had stopped;
then the water rushed out towards the Canal as if someone pulled a plug in a tub - the 50cm of water receded in less than 20mins.

This pattern is very consistent with what is alleged in this thread, i.e., someone left the gates closed, then after it became too late, opened them.

Airlib · Jul 21, 2010

Sounds like a case of cannot convince you... confuse you...
So now start blasting all sort of technical terms lah.. what upper limit, lower limit... hump bah lam limit also come out...

here they eat briyani, drink teh tarik, learn french cooking, sing uptown songs, take turns in replacing bulbs to light-up the end of the tunnel to see the oncoming mrt train betterer, scratch their balls all day, smell their fingers and think of the fat paycheck coming their way next week....sweet farkall but it's a great life to live their dreams

Marina barrage is causing Singapore flood problem. Because PAP gov. want to keep water level at certain limit to save water. as we can sea clearly that when PUB open the gate the inside Marina barrage water level is about 1m higher than sea level sea the Mediacock video. If they release water earlier such serious flood will not happen at all.
All because PUB keep water too much.
Our minister have calculate the water level wrong, they should revise the upper level limit or reduce 1m water level.

longbow · Jul 21, 2010

Must take into account time it takes to pump out water!!!

Looks like they are trying to save water. What we are experiencing is flash flood. By the time you see flooding it is too late! So you have to pump out water before it hits. In a way it is also admittance that high levels in Barrage caused some of the flooding (it creates an artificial high tide situation as canal water has no way to go).

I see a potential problem for them. To maintain a lower water left greatly reduces the water capacity.

But then since Gov is not liable for people's losses and since it can make $$$ from selling water. Then they will be biased towards saving water.

myo539 · Jul 21, 2010

Why so kancheong one? The moment it rains, must open floodgates? Even when you unzipped your trousers, you need a while before you pee.

It appears that there are either too many experts here giving unsolicited consultancy services or too many armchair critics who only know how to shoot from their mouth.

Let's us enjoy the new waterfront scenery while it last before PUB comes up with fantastic solutions. Kiasu people had to pay through their nose to enjoy waterfront scenery. Here we have water at our doorsteps. Hey, even Rebecca knows how to enjoy herself and make the best opportunity :

By the way, why no body praised HDB high and low when no report was received about housing estates getting flooded? Why so stingy in praises?

PAP IS IGNORANT. YOU SIMPLY CAN'T HAVE THE BEST OF BOTH WORLDS.

When lightning strikes merlion, people say very bad omen - the world is coming to an end. But it didn't.

When Marina Sands was built, people say very bad omen, but Sands is making money and laughing all the way to the bank.

When one tree fell by strong wind, people say bad omen. When two trees fell, people say very bad omen. When three trees fell, people say very, very bad omen.

When is omen going to be an omen? The world is coming to an end, that's for sure. But you and I won't be around for the next 1000 trillion years.

Should you have constipation or diarrhoea, it's sure is a bad omen for your body - better see a doctor.

The omens are shown way ahead of what they are warning, repeated omens hint something very strong and significant will eventually come. They are not immediately answered. And idiots will still laugh until they suddenly don't know how to cry.

PAP's evil icon logo is shown this time, Red Hot Lighting struck through The Blue Circle.

The circle of Singapore flyer icon is repeatedly damaged, It means PAP logo is smashed by heaven to be hacked apart along center line just like how the logo is drawn, The heavenly energy is red hot from the top. The effects will be very strong and very final.

if they adjust the min water level in the reservoir, taps will run dry. Fapee has put peesai in a fix after terminating the water agreement with msia.

They should revise the minister's salaries in accordance to the performances of the ministry they run, their work for the constiuents & their contribution to society...in short, in any other countries on planet earth...THEY WOULD GET A MARCHING ORDER...for the fiasco caused.

No need to explain, play taichi...or even berate the voters...such arrogance! :mad:

So what is the capacity of the pumps? How many litres/min? Does it pump out water as fast as the as when the flood gates are open?

Those engineers in PUB and SPower had cock ups before. Remember the big island wide black out we had in 2004? The gas valve (one and nly) that controls the flow of gas from Indonesia broke down and the redundant generators couldn't kick in on time. Billions were lost. The fat cats of course got away. Uniquely Singapore!!

They will get a MARCHING ORDER yes perhaps. But some will be given cushy retirement jobs in the GLCs. Ex Acting Minister Peter Lim went to NOL. Ex MP Goh Chee Hwee took charge of NTUC comfort to draw S$1.4M bonus while taxi drivers struggle for a living. Some will still fark up the GLCs.

If Yakult doesn't make it to full minister he could still be chairman of the Zoo, and but should fed to the lions if he farks up further.

The best thing we can do for the country is to vote some of these IDIOTS out. DO YOUR JOB if you love your country.

Solve flood = singapore no more water to drink??

PUB please wake up your idea.

Unfortunately it is not a straw man argument. A heavy rainy period is usually followed by a dry period.

We are running into these problems because of our population growth. The rapid population growth has naturally increased the amount of water that we need. Unfortunately we do not have the space to build new reservoirs. So exisiting reservoirs have to maintain a level of reserves that is higher than what was originally planned for. Due to the high level of reserves, the repeated system failures show that the system is unable to discharge the surplus water when there is rainfall of more than 170 mm.

PUB Admitted Delay in Opening Marina Barrage Floodgates!
