CHIANG MAI – As the sun rose over Chiang Mai this Tuesday, April 14, residents were met with a sight that stood in stark contrast to the festive spirit of Songkran. While the city remains in the grip of the world-famous water festival, a wave of public outrage has hit social media following reports of massive littering at one of the city’s busiest intersections.
The aftermath of a large-scale concert and water-splashing event at the Rin Kham Intersection has left a trail of waste stretching over a kilometer, sparking a heated debate about corporate responsibility and civic duty during Thailand’s most celebrated holiday.
According to reports from Manager Online, the event—which drew tens of thousands of revelers—transformed the area around a well-known shopping mall into a sea of plastic bags, water buckets, food containers, and discarded raincoats.
What has particularly incensed locals is the disparity in cleanliness between private and public spaces. Eyewitnesses noted that while the mall’s immediate perimeter was cleaned to a “spotless” finish shortly after the music stopped, the surrounding public roads and sidewalks remained buried under debris.
“It’s disappointing to see,” said one resident who shared photos of the mess online. “They made a lot of money from the crowds, but they left the mess for the city to clean up. It’s like they care about their own doorstep but don’t care about the community.”

The Scope of the Problem
The littering issue wasn’t just a minor inconvenience; it posed actual risks to the city’s infrastructure and safety:
- Traffic Hazards: The scattered plastic and debris became a slipping hazard for motorcyclists navigating the intersection.
- Drainage Concerns: With Chiang Mai facing occasional summer storms, residents worry that the plastic waste will clog city drains, leading to flash flooding.
- Environmental Impact: Much of the waste consisted of single-use plastics, which are notoriously difficult to manage during large-scale festivals.
In Thailand, the responsibility for post-event cleanup is often a grey area between private organizers and local municipalities. However, the sheer volume of trash left behind at the Rin Kham Intersection has led many to call for stricter enforcement of “clean as you go” policies for event organizers.
Under Thai Public Cleansing Laws, businesses and organizers are generally expected to ensure that their activities do not negatively impact public hygiene. In this case, the lack of a coordinated cleanup plan has left the Chiang Mai Municipality and the Highways Department to pick up the pieces—and the bill.

A Growing Call for “Sustainable Songkran”
This incident has reignited a broader conversation about how Chiang Mai handles its massive influx of tourists. While the economic benefits of Songkran are undeniable, the environmental cost is becoming harder for locals to ignore.
Tourism experts suggest that for Chiang Mai to maintain its status as a top global destination, future events must prioritize:
- Waste Management Systems: Placing high-capacity bins every few meters in high-traffic zones.
- Real-Time Cleanup: Hiring dedicated teams to clear debris throughout the event, rather than waiting for the following morning.
- Corporate Accountability: Requiring organizers to post a “cleanup bond” that is only returned if the area is restored to its original state.
With two days left in the Songkran festival, the eyes of the public are now firmly on the event organizers and local authorities. There is a strong demand for a more proactive approach to ensure that the final days of the Thai New Year are remembered for their joy and tradition, rather than their trash.
As the city prepares for the final “water wars,” the message from Chiang Mai residents is clear: celebrate as much as you like, but respect the city that hosts you.
