UNITED NEWS INTERNATIONAL (UNI) — Philippine President Rodrigo Duterte threatened to close one of the country’s biggest tourist attractions which he described as a “sewer pool.”

Boracay Island, known for its white sand beaches brings in P56 billion, or about $1.12 billion in annual revenue.

At a business forum on Feb. 9, Duterte said local government officials created a disaster by approving construction without proper sewage, covering the island’s famous beaches with feces.

Three days later he threatened to file charges of serious neglect of duty against Boracay officials for making the island into a “sewer pool.”

One Tourism Department spokesman said many businesses drain their sewage directly into the sea and over-development has caused buildings to spill out onto beaches and roads.

Duterte said he gave Environment Minister Roy Cimatu six months to clean up the island.
