Flash flooding is not a new phenomenon in every country. Flash floods result from intense rainfall. Like the usual floods you all know, they are caused by heavy rainfalls as well as broken dams and overflowing lakes. It spreads rapidly to roads, homes, buildings, and other places that contain water.
Singapore has recently experienced a major overflow of water. Continual heavy rainfall forced them to close other roads and caused severe traffic jams. Even Bukit Timah Plaza in Singapore was affected. It was the month’s second strongest rainfall. Additionally, the rainfall recorded on Bukit Panjang Road was Singapore’s highest rainfall recorded in a single day since 1981.
In many countries, every rainy season brings floods and flash floods that affect every resident. No matter where they live, whether rich or poor, floods affect everyone. There is nothing anyone can do to stop or prevent them.
Flash flood is basically from the word “flash”, the quick response of heavy rainfall. In a short period, the water can increase up to inches depending on the situation. Whether it might be an overflow of lakes or dams, clogged rivers, and water canals, or any water passage that cannot accommodate more water.
The recent flash flood incident in Singapore was caused by a clash of winds blowing from the north and south. There has been a heavy downpour due to too much moisture and pressure added to the clouds. In the constant flow of water to the ground, there is not enough room for water to circulate and flow in other areas, resulting in high flood levels.
According to Koh Tieh Yong, a weather and climate scientist at Singapore University of Social Sciences (SUSS), some air is forced upwards when two strong winds cross each other. Rain clouds form as a result of this force of air, causing heavy rainfalls.
In addition to sewer flooding, flash floods can also occur. Several factors can cause sewer flooding, including clogged or blocked pipes and heavy rainfall. Floods are often caused by some people flushing their personal items down both public sewers and home drainage pipes that are not supposed to be flushed. Common items such as feminine napkins, tissue, and baby wipes or newspapers. It stacks together on drainage pipes causing blockages, and flooding.

Singaporeans have posted on social media different angles of why there was heavy rain in Bukit Timah plaza. The videos showed water dripping from the ceiling and wet floors throughout the mall.
According to a news article by CNA, tenants of the mall’s shops were using blowers to dry the wet floors. The heavy rain that began around 10:30 am, non-stop, soaked some areas of the mall with carpet floors as well.

One of the employees from the plaza also mentioned that one of the ceilings below the escalators had collapsed the same morning. The plaza’s management also decided to stop the escalator from operating due to the damage caused by the flood.
The flood has started to enter the Bukit Timah plaza from the pedestrian walkway nearby. It gradually started from the ceiling of the mall until it eventually collapsed, which had led to more area for water to get inside the mall’s vicinity.
Because of the incident, the National water agency PUB issued flood risk warnings to cover four different locations where water levels in local drains and canals had peaked up to 90 percent. These areas include Upper Bukit Timah Road from Hazel Park Terrace to Chestnut Drive, Kranji Expressway at Woodlands Road exit, Sime Darby Centre, and Sunset Drive/Sunset Way.
Even if you don’t live in a space as big as Bukit Timah Plaza or your drainage system is not as wide as the country’s, you should still protect your interior from flooding. By doing so, you prevent leaks in the interior. Even, let’s say, you live in a high-rise building, water leakage can cause as great damage as floods.
Water leakage is hard to prevent from houses because there are so many possible passages where water can get through. It can get through walls, floors, and roofs. However, you may think that as of now, there is not much moisture or water penetrating through these places, but take note, that these small amounts of water may be the start to cause bigger damages. This includes molds and structural damages.
