Bangkok's drainage systems are under scrutiny as heavy rain is forecasted to continue in the Thai capital. The assurance of their efficacy comes amid reports of flooding in several low-lying areas after recent intense rainfall.

 

The Bangkok Metropolitan Administration (BMA) has emphatically stated that the city's drainage infrastructure can handle the surge in rainwater. Over the weekend, significant rainfall saw about 14.05 million cubic metres of water descend onto the city. This caused widespread concern among residents fearful of potential flooding.

 

According to Aekvarunyoo Amrapala, a BMA spokesperson, the systems are prepared for such challenges. Nonetheless, the past days have witnessed exceptionally heavy showers, sparking anxiety about the city's ability to stay dry.

 

Typically, September in Bangkok sees its fair share of rain, but recent downpours have been particularly severe. Jetsada Juntaraprapha, director of the BMA's Drainage and Sewerage Department, noted that the heaviest rainfall occurred on Friday, with an astonishing 130 millimetres measured across the city. Thawi Watthana district recorded the most significant deluge at 157mm.

 

Mr Jetsada attributed this extreme weather pattern, at least in part, to climate change, a global phenomenon impacting local weather systems and exacerbating heavy rainfall.

 

On Monday, around 80% of Bangkok experienced moderate to heavy rain, with water levels reaching 0.46 metres above sea level at the Lat Krabang water gate, surpassing the critical threshold of 0.35 metres.

 

Specific areas have been particularly affected—Khlong Prawet-Ruam Phattana Road registered some 94mm of rain in just 24 hours. Similarly, Khlong Bang Na-Sri Nakarin in Bang Na recorded 84.5mm, while Khlong Sanam Chai-Khlong Bang Khun Tien in Chom Thong district saw 57.5mm.

 

The sheer volume of rainwater has inundated some of Bangkok's minor canals, triggering minor flooding in low-lying districts. This challenge underscores the importance of maintaining a clear and efficient drainage system.

 

Officials have highlighted the importance of public cooperation in ensuring the drains function optimally. Mr Jetsada emphasised the need for residents to avoid dumping waste in sewers, which hinders water flow and accentuates flooding risks.

 

As more rain is expected in the coming days, the spotlight remains firmly on Bangkok's drainage and emergency response strategies. The city's preparation and management of its water systems are critical in weathering this meteorological storm.

 

For now, residents are urged to stay vigilant and take necessary precautions, as the BMA coordinates with relevant agencies to manage water flow efficiently and mitigate further risks.

 

The events in Bangkok point to broader issues of urban flooding and climate adaptation. As cities worldwide face similar weather extremes, innovative infrastructural solutions are needed to protect urban environments and their inhabitants from the evolving challenges posed by climate change.

 

In conclusion, while Bangkok’s drainage systems are reportedly up to the task, the unfolding situation serves as a stark reminder of the urgent need to address the impacts of our changing climate.

When the sponge is full of water where can it go ?

Not long now before Bangkok sinks into the sea!

 

 

 

Facts to consider: The city sits only 1.5 meters above sea level. By 2030, flooding frequency and intensity are expected to surge. By 2050, without large-scale interventions, Bangkok could be entirely submerged. (Google)

How does one calculate 14.05 million cubic metres to have fallen, I am no scientist or mathematical genius but this seems a for an impossible task for anyone.

Thanks to the heavy rainfall throughout this kingdom,

I predict the price of gluteneous rice(Khao Niao) remain stable and affordable to anyone(23-30/kg) continues on.

 

Several years ago, its price hiked significantly due to rainfall shortage(50b/kg).
