The authorities have taken action against two restaurants in the popular tourist destination of Krabi for releasing wastewater into a canal that drains into the sea.

Tourists in the area have complained about the foul odour from the waste, and authorities say it has adversely affected tourism.

“We will inspect all businesses along the Chak Canal that drains into Ao Nang and punish all who release untreated wastewater,” Deputy Krabi Governor Somkuan Khan-ngern said on Sunday.

There are many restaurants and resorts along the canal, though so far, only two restaurants – Thailandia and Taj Palace – have been caught releasing untreated wastewater. Owners of the restaurants have been fined Bt10,000 each for violating the law governing cleanliness in public places.

Somkuan added that the authorities will also work urgently on improving water quality in the area.

“We will use several measures,” he said, adding that in the long run, he will also seek a budget to develop a comprehensive wastewater treatment system.
