We need external auditors and/or consultant to get to the root cause of the flood incidents. PUB and the govt have lost their credibililty as they have been giving lame excuses and half truth over the matter. It is easily to make sweeping statement like it has nothing to do with the barrage. Where is the supporting evidence ?
If the Marine Barrage is the cause of the flood, it will be too embarrassing for them and unlikely we will ever get wind about it. After all it is one of the latest 'show case' of our nation, costing millions.
Now our Minister is blaming it on the 'unstable' weather. Likely he has never heard of the saying : Unpredictable as the weather. What is the purpose of planning and designing for redundancy if our relatively new drainage system is found to be under capacity ? Who is the govt body approving the design of the drainage system ?
Investigation is getting to all the root causes of the matter. It is not about coming up with more excuses and trying to point fingers in another direction to distract from being accountable and responsible.
PUB will be installing more flood sensors to give early warning. But exactly how much time people have for flood preparation is not mention. What is the purpose of all these sensors if the preparation time is not sufficient ?
Besides, flood warning system is not preventive measure - it is reactive. Having more sensors may result in more false alarms. When people hear the cry of wolves too often, they may not react when the real wolves come.
It will also jack up maintenance cost. Should there be frequent false alarm, it could cause public inconvenient. Low standard of investigation done will only result in inefficiency and ineffectiveness when addressing the flood problem, as the root causes are not address.
