Flash Floods on 8 January Morning

Flash floods occurred in nine reported locations in eastern Singapore due to intense rain on the morning of 8 January 2018. PUB officers were immediately deployed to the flooded locations to investigate and render assistance.

The areas were:

  1. Tampines Road (Opp Jalan Teliti)
  2. Tampines Ave 12 (Opp Tampines Eco Green)
  3. Arumugam Road
  4. Sims Ave/Eunos Road 8
  5. Sims Ave/Tanjong Katong Road
  6. Jalan Nipah
  7. Bedok Road/New Upper Changi Road
  8. Upper Changi Road/Bedok North Ave 4
  9. Bedok Road/Upper Changi Road East

There are ongoing drainage improvement works to improve flood protection for these locations. To read the press release, please click here.

Flood Monitoring Efforts

Upon receiving heavy rain warnings, PUB will monitor water level sensors and CCTVs from its 24-hour Operation Room. Officers from the Quick Response Team will be on ground to offer assistance and check canals/drains. Flood updates will also be shared on PUB FaceBook, Twitter and MyWaters Mobile App.

Stay Updated 

When encountering heavy rains, members of the public are advised to tune in to radio broadcast for traffic watch updates, refer to PUB’s FaceBook at www.facebook.com/PUBSg or PUB’s mobile app “MyWaters” for flood alerts and updates. In view of safety, do choose an alternate route. Read more on what to do during a flash flood.

Water Level Sensors

There are about 200 water level sensors islandwide to monitor real-time water levels in drains and canals. Members of the public can subscribe to water level sensors alerts via PUB’s mobile app “MyWaters” or check out “live” info of water level in canals here.  

Drainage Upgrading Works

Since 2012, drains and canals at about 327 locations have been upgraded. There are ongoing works at 73 locations and upcoming works at another 22 locations.

Enhancing Drains to Cope with More Rain

The day-to-day work of drainage engineers in PUB involves coming up with ingenious solutions to tackle varied challenges in drainage projects, which are often massive and complex. This includes encountering hard rock during excavation, diverting underground services, carrying out concurrent work activities within tight spaces onsite and labouring eight storeys underground. 

The media was given a glimpse of this exciting challenges at a briefing cum visit to the Bukit Timah First Diversion Canal (BTFDC). 

Drainage Improvement
Ongoing works at Bukit Timah First Diversion Canal – Phase 3 (Holland Green to Clementi Road)

Built in 1972, the BTFDC runs 3.2km long, from Bukit Timah Road near Maple Avenue to Clementi Road. Its expansion works is ongoing and when completed in 2018, will give the upper Bukit Timah catchment more flood protection. 

BTFDC runs through unique and historically-rich terrain. A section of the canal goes through Military Hill and the conventional approach of open trench digging cannot be used. Instead, C&W engineers have to use tunnelling to create two new tunnels under the hill. These new tunnels, the size of MRT tunnels, will supplement the existing tunnels in conveying more rainwater.

As part of the Bukit Timah First Diversion Canal expansion, two new tunnels were created to supplement two existing tunnels under the Military Hill. Above picture shows one of the new tunnels.

With upgrading works taking place in a “live” canal, engineers have to ensure that BTFDC continues its function of channelling stormwater away quickly, and its drainage capacity is never compromised.

Extensive Investment in Drainage Infrastructure

The Government has spent some $1.2billion on drainage improvement works islandwide since 2011 to increase flood protection for Singapore. Drainage projects at 325 locations have been completed over the past 6 years. 

PUB is preparing for more intense rainfall and the frequency of such rain events to happen more often.  In the next 2 to 3 years, the Government plans to spend a further $500 million to upgrade more drains, and the public can look forward to drainage improvement works commencing at 16 locations in the coming year. 

There are also ongoing drainage projects taking place at 75 locations. Besides BTFDC, these include Sungei Pandan Kechil, Stamford Detention Tank and Stamford Diversion Canal.

Following the Water Efficiency Awards (WEA) and Industrial Water Solutions Forum on 21 November, Ms Irene Toh (PUB) and Mr Philip Chan (Asia Square) shared the measures and initiatives on water efficiency with the audience of MediaCorp’s popular Chinese radio station Capital 95.8FM.  

Irene explained that WEA is a biennial award which recognizes the top water efficiency performers in the respective sectors. She described how the best performers are chosen based on Water Efficiency Index (WEI) by sector, or industrial plants with the highest recycling rates. She also added that PUB has complied a publication "Best Practice Guide for Water Efficiency - Buildings" and is seeking comments from the industry to further refine this document.

Asia Square Tower 2, a recipient of WEA, was represented by its Sustainability Manger Mr Philip Chan. He shared the importance of water efficiency to them and the types of water efficient fittings and appliances they have installed. In addition, he carries out checks upon receiving feedback on leakage or inefficiency in water fittings.

The Quest for Water Security

A two-page comic depicts Singapore's quest for water security through three chapters: "Early Struggles & Resolve: Local Catchments", "Across the Causeway: Imported Water", and "The Way Forward: NEWater and Desalinated water".

This comic highlights the challenges Singapore faced as a nation with little natural water resources, and how these challenges were overcome with the Four National Taps. Moving forward, R&D and technology would be key in maintaining a sustainable water supply for Singapore.
