CHONBURI — 4 July 2026, Heavy rain in Chonburi triggered environmental concerns on Saturday after black wastewater was seen flowing from a drainage pipe into the sea at Jomtien Beach in Pattaya.
The incident drew public attention after Chonburi MP Thanatharn Pramoonpong posted a video showing dark water being discharged into the sea, raising concerns over pollution and the impact on Pattaya’s tourism image.
Reporters later inspected the area near tourist boat ramp A, opposite Siam Commercial Bank on Jomtien Beach, and found black water was still flowing from the drainage pipe into the sea, although the volume had begun to decrease after the rain stopped.
Local boat operators said the problem occurs repeatedly during heavy rain and has affected their work, as runoff from the pipe has eroded part of the boat ramp, making it difficult to move boats in and out of the water.
They called on Pattaya City and relevant agencies to find a permanent solution, saying the recurring discharge not only affects operators but also damages the image of one of the city’s main tourist beaches.
The blackwater incident came as heavy rain also caused damage elsewhere in Chonburi. In Si Racha district, part of a wall at a factory under construction reportedly collapsed, allowing large amounts of foam packaging waste to spill into nearby communities.
Residents said the foam fragments were scattered through streets and drainage areas, prompting concerns over environmental damage and calls for a thorough clean-up and investigation into the construction site.
Authorities have been urged to inspect both incidents and ensure measures are taken to prevent similar problems during future heavy rain.
