Debris traps for Canal
by Grace Chua
THE PUB is spending $25,000 to install five debris-trap gratings at Stamford Canal to prevent future floods. All five will be in place by Friday.
Last week, massive floods hit the prime Orchard Road shopping belt because of a clogged drain at the canal, which is meant to clear water away from Orchard Road.
After the flood, the national water agency said it would install more of these grates along Stamford Canal and step up maintenance checks at the canal to once a month, from once every three to six months.
The PUB is spending $150 million a year for the next five years to upgrade drainage infrastructure, it said last week. Gratings are placed in strategic areas picked by PUB engineers who model the water flow in canals.
The five new zig-zag gratings, which catch debris without stopping water flow, are in open drains (for easy maintenance) at Camp Road, Napier Road near Minden Road, Nassim Road, Grange Road and Tanglin Road.
They add to the Marina Reservoir catchment's 100 existing gratings and 26 float booms (to catch flotsam) at the mouths of canals.

If there's another flood at Orchard area I wonder what's the next excuse.

Maybe they wanted caterpillers to eat up all the leaves so no more leaves clogging up the drains.
Maybe.
Just maybe.

I like to see the debris traps catch some debris. At the same time I hope not to see the floods at orchard road repeat itself with no debris in the debris traps.

If the debris traps catch all the massive debris, won't it still clog up the drain?
Sorry, I am no civil engineer.

Debris traps are as good as useless if no one cleans them up. Who was supposed to clean those drains, anyway?

The debris traps will definitely require more maintenance as debris will get stuck on the traps. This will lead to increase in maintenance costs to maintain the traps to ensure the traps remain debris free or else the drains will gets clogged up anyway.
I expect an increase in bills to the public in one way or another soon because of this.
On a side note, i saw on tv earlier, heaps of soil-waste being dug up from the drains....one has to wonder where they come from. Either they are from construction worksites or soil erosion. Either of which, the question is, shouldnt the problem be nipped in the source before it reaches the drain instead of wasting money and effort in having to maintain the drains? Take note that soil can still pass through these traps.
I personally is of the opinion that we are not hearing the truth from the authorities as to the cause of the flood. I suspect the massive construction works along Orchard Road might have been the actual cause of the flood and the soil-waste.

"By Friday"? So was PUB late or were the traps useless?
