Up to 20 fire engines were dispatched to put out the blaze at the 32-rai dumpster in tambon Ban Pom, which is about 2 kilometres from the city area. The fire was still raging at the time of press.
Deputy mayor Preecha Khanthapaisri said the dumpster caught fire at around 2pm near a rice field and the flames ravaged a 7-metre high pile of trash.
The informed source said the fire also resulted in black smoke, which was visible from afar, and that firefighters and backhoes took two hours to limit the fire.
Preecha said the dumpster was being temporarily used to store garbage while the city's incineration facility construction is still being planned.
He cited an official's report that some farmers were burning farm wastes in the area east to the dumpster and strong winds had sent sparks to the garbage pile, setting it on fire.
