The other thread was spotted with criticisms on the local govt as such is closed. Wow, this sgf cannot tolerate people criticise govt, so petty, narrow minded, or is it just one person that is against it, hahahah.

More buildings means less water will return to the water table underground, means there will be more run offs to the drains.

If the capacity of the drains are not increased it usually leads to flooding.

Goes to show that PAP is more a feedback system than a feedforward system.

When it rains, water from most urban buildings and hard surfaces is directed through downpipes, drains and gullies into the drainage system. Some downpipes from the roofs of domestic properties are directed into a soak-away and so return to the water table naturally but in urban areas, or from large buildings the water is whisked away into drainage systems.

it takes time....give'em a break...

but the idea of strainers or meshed gratings was such a primitive used in many estates were now adopted by govt? strange......perhaps in terms of costs, it is the cheapest....

no doubt a temporary measure.....more high tech methods should be explored than just relying on meshes or strainers....bio-degradable is still costly

Maybe old man wore red underwear today, that's why it rained.

But seriously, the rainfall from the 16th and 25th of June would hardly qualify as heavy rainfall, we have seen higher rainfalls than that but the drainage system did not cause any floods then.

Urban floods are when land is converted from fields or woodlands to roads and parking lots; it loses it ability to absorb rainfall. Urbanization increases runoff two to six times over what would occur in natural terrain. During urban flooding, streets can become swift moving rivers, while basements can become deadly as they fill with water. (Flooding Takes Many Forms: NWSFO) (Flood and Flash Flood Occurrence)
