Overflow waste problem in Koh Samui. Caused by faulty waste incinerator for more than 4 years from the end of the year 2552 (2009) and did not repair the municipality of Koh Samui. Changborisat therefore not worth claiming private incinerator job instead, but now more and more waste (2556 (2013)) odor. Waste water flowing into the public stream. Create a trouble to the locals and Koh Samui tourist attractions of the country's main push Thai.
