SINGAPORE - The Public Utilities Board (PUB) has found the cause of striking blue water in Bishan's canal yesterday, May 29, and has cleared up the drain.
Stomp contributor Pauline had spotted the bright artificial blue colour of the canal at Binchang Rise, and was concerned about what happened.
In response to the Stomp article "What caused this? Canal in Bishan turns into a shocking, artificial blue" dated May 29, PUB's checks have revealed that paint had tipped over into the drain at one of the factories at Jalan Pemimpin.
This is their reply in full:
"PUB detected a blue discharge in a drain at Clover Way at 5.30pm. PUB officers were mobilised to site immediately to investigate.
