Naklua residents near the Nok Yang canal claim local businesses are dumping sewage and chemicals into the waterway, causing stinky pollution.
Locals living near the middle of the khlong alleged the wastewater was released by hotels, car care centers and a steel factory, but offered no proof as to which ones, if any, actually did.
Nonetheless, the water is black and the middle of the canal is obstructed by both weeds, marine plants and garbage.
Residents called on city hall to dredge the middle of the canal – they said Pattaya previously only dredged the ends – and hunt down those dumping sewage.
The residents insisted no one in their neighborhood would do such a thing as they all pledged a while back to preserve the waterway which, once long ago, people could swim and fish in.
