Singapore — A member of the public shared a video in which alarmingly red water could be seen flowing down a drain on Reddit, a popular social news website and forum.

She shared the video to a subreddit known as “r/singapore” to remark on the sight.

According to the netizen, the strange sight occurred in one of Marsiling’s drains. In her caption, she questioned what could have happened to lead to such a strange phenomenon.

“What is going on? Why is the water RED?????” the netizen asked.

Other netizens took to the comments section to share their views and jokes about the sight.

Some netizens remarked that the colour was somewhat similar to that of Bandung, a popular drink in Southeast Asia.

A few other netizens joked that this could perhaps be part of a publicity stunt to commemorate the nation’s upcoming 56th birthday.

Another netizen cleverly quipped that this was part of the process where the red lines for MRT journeys are drawn out on Google Maps.

A few netizens also urged the poster to bring up the matter to the relevant authorities, such as the National Environment Agency (NEA) or the Public Utilities Board (PUB).

Another netizen suggested that the colouring could have been the result of a red algae bloom, but yet another netizen said that the colour was far too vivid and was more likely caused by man-made reasons instead.

Five years ago, a similar incident occurred in which water in a canal at Jurong West Street 62 turned crimson during an afternoon, shocking residents in the vicinity since there were no factories nearby. However, the colour of the water in the canal then looks vastly different from the one filmed in the Reddit post above.
