(Update: In an article at Today, PUB highlighted that the rain on Dec 23 "caused some parts of Stamford Canal to be full" and "At Liat Towers, rainwater that drained off from the roof and the back area of the building overflowed into the basement area from an internal drain, as the water could not be discharged into the canal, which was full".

Wrote The Straits Times,
A spokesman for the management of the shopping and office block, speaking to The Straits Times following a meeting with PUB, pinned the blame on an over-full Stamford Canal.
PUB, on the other hand, is adamant that the build-up of water came from the heavy rain and the building not pumping out the water fast enough.
Just look at the pictures. It's muddy brown water. If it's ponding water, it shouldn't be brown. Means that water came from the drains. It's backflow from the flooded canals.One has to wonder if the blame will now be on Starbucks for turning the "ponding" brown because of their coffee beans.
