More than one thousand tourists arrive on Phi Phi daily. This figure does not include those who arrive by chartered speedboat or yacht. Phi Phi produces about of solid waste a day, rising to during the high season and most of this waste leaves Phi Phi island into the ocean - untreated; in fact, Phi Phi Island releases 83% wastewater untreated. All tourists arriving on the island pay a 20-baht fee at Ton Sai Pier to assist in "keeping Ko Phi Phi clean". "We collect up to 20,000 baht a day from tourists at the pier. The money is then used to pay a private company to haul the rubbish from the island to the mainland in Krabi to be disposed of", Mr Pankum Kittithonkun, Ao Nang Administration Organization ("OrBorTor") President, said. The boat takes about 25 tonnes of trash from the island daily, weather permitting. "Ao Nang OrBorTor" pays 600,000 baht per month for the service. During high season, an Ao Nang "OrBorTor" boat is used to help transport the overflow of rubbish. Further aggravating Phi Phi's waste issues is sewage. "We have no wastewater management plant there. Our only hope is that hotels, restaurants and other businesses act responsibly – but I have no faith in them," Mr Pankum said. "They of course have to treat their own wastewater before releasing it into the sea, but they very well could just be turning the devices on before officers arrive to check them." The fundamental issue is that the budget allocated for Ao Nang and Phi Phi is based on its registered population, not on the number of people it hosts every year, Mr Pankum said.
