ICYMI: Flash Floods in Singapore on Last Week
Heavy rain can cause floods, but it will increase due to clogged drainage, especially in lower areas.
Last 9 November, the Public Utility Board, Singapore's National Water Agency, informed that the heavy rain might cause flash floods at several ranges, including northern, western, and central areas. After a few minutes, they updated and announced that some of the water levels in drainage canals were at 90%.
King's Road in Bukit Timah is one of the areas affected by the flash floods. In a video uploaded by the SG Road Vigilante on YouTube, flash floods soaked parked cars and houses. There is also debris and rubbish floating around.
According to the PUB's spokesperson, the clogged drainage worsened the effect of the heavy rains at King's Road.
"PUB received feedback from residents at around 3:30 pm on flooding that occurred along a 50m stretch of King's Road in the Bukit Timah area, which is not a flood hotspot." PUB added.
Because of a flash flood risk, the PUB created a Telegram channel updated into the concerned areas. Thankfully, the flood submerged after a few hours.
The following day, workers cleaned the drainage at the King's Road and got ten bags of slit along with leaves that clogged the water drainage. The PUB made their post-flood investigation and found that grass clippings clogged King's and Price Road's inlet chambers.
According to the PUB, "These inlet chambers are meant to channel rainwater runoff from the road into the drainage system and must not be blocked. We assessed that this blockage was the cause of the flooding,"
"After the debris in the inlet chambers had been cleared, Public Utility Board checked the recent activities in the area and learned that there were grass cutting works done in the morning on the same day. We are reaching out to the relevant parties to follow up."
On the other hand, some construction workers at the Thompson Road, Novena, moved the road barriers that we're slowly drifting away due to the floodwaters on Tuesday. Tiktok user Teriruim uploaded a video of the three construction workers managing the barriers to help drivers get through safely.
Based on the report of the Meteorological Service of Singapore that this month will have more rainy days. It is essential to throw rubbish properly to limit these floods from reoccurring. Clogged drainage allows the rise of the water levels and results in flooding, especially in prone areas.
