Singapore Invests S$150 Million in Drainage Upgrades to Bolster Flood Resilience

Singapore Invests in Flood Resilience with Drainage Upgrades

Singapore is taking proactive steps to strengthen its flood resilience in the face of increasing climate change risks. The government has allocated approximately S$150 million (US$110.6 million) for drainage upgrading projects in the 2025 financial year.

This investment builds upon the 19 ongoing drainage improvement projects, with six more scheduled to commence in 2025. The announcement comes in response to concerns raised by Members of Parliament following two recent monsoon surges that brought prolonged rainfall to Singapore in January 2024.

During the first surge, Changi recorded over 255mm of rainfall, exceeding the average monthly rainfall for January. While most areas remained unaffected, one incident of flooding occurred along Jalan Seaview in Mountbatten. The flooding, which lasted about three hours, reached a depth of 0.3m and caused water to enter the car porch of a nearby house.

This localized flooding highlights the ongoing challenges posed by rising sea levels and tidal floods. While the roadside drains at Jalan Seaview were upgraded in 2014, some areas remain vulnerable due to road levels being slightly above the high tide level.

To address this long-term concern, the government plans to reclaim land and build Long Island. This project aims to protect the East Coast area, including Jalan Seaview, from rising sea levels and tidal floods.

The government's commitment to drainage upgrades and long-term flood mitigation strategies demonstrates its proactive approach to safeguarding Singapore's infrastructure and communities from the impacts of climate change.
