Vehicles were left stranded at the junction between Chai Chee Road and New Upper Changi Road on Wednesday after the area was flooded again. This after heavy showers caused flash flooding at the same junction on Monday.

Mr Zheng Ji, a hawker at Foodhub@Chai Chee located at 26A Chai Chee Road, said he has seen the junction flood at least 10 times over the past three years. "Every time there is a heavy rain, the junction will flood," said the 54-year-old. "Sometimes, aunties will fall into the drain at the side when the water overflows."

With flood risks in mind, national water agency PUB has stepped up drainage maintenance efforts from once to three times a week. It will also inspect 100 construction sites to ensure nearby drains remain obstacle-free.
