ELDERLY Tai O residents are opposing moves to rehouse them in a modern estate because they do not want to deal with flush toilets and lifts. They also face a massive rent increase. Their wooden huts on the bank of Tai O Creek, which cuts through the village on Lantau Island, are being cleared to make way for a sheltered anchorage. Residents will be rehoused in a nearby estate, Lung Tin Estate II, which will be completed by the end of the year. Leung Yau-fuk, 79, said he was worried whether he could afford the rent in the new estate. He and his wife Chan Loy-ho, 70, now pay only $7 a year for their hut. ''We have no income. How can we pay for the rent? The Government should lower the rent and give us subsidies or we would rather sleep in the street,'' he said. The Lung Tin Estate II will provide 550 flats for 2,000 residents. Rents will range from $455 to $1,510 per month for a 175-square-foot to a 580-square-foot home. Tai O fishing village is famous for its maze of stilt houses. Most are 200 square foot, single or two-storey, and equipped with televisions, fridges and telephones - but not flush toilets. The toilets are built on stilts and waste goes straight into the river. Cheung Chan But-choi, 78, said she, her father and grandfather were born in Tai O and she did not want to move. ''It is very convenient living here. I need not clear my rubbish or flush the toilet because I can just throw the waste out of my house into the river. ''Besides, neighbours here are very close. We can leave our doors open without worrying about our belongings being stolen. I wonder if we can enjoy such a natural and quiet environment in a housing estate,'' she said. Lee Chi-fung, chairman of Tai O Rural Committee, said villagers were worried because they had not been told details of the clearance and rehousing. ''All we know is that the project will be started early next year after the completion of the new housing estate. But details of how many huts will be cleared and how much villagers will be compensated are still not known. ''We will call for a meeting with various government departments in the near future to ask officials to explain to us what they are going to do here. We don't want to be kept in the dark,'' he said. The $100-million proposal was first raised in 1985 because Tai O Creek was becoming increasingly shallow, making anchoring difficult. But in 1992 the Government postponed the project until January next year because of financial constraints. With only five months to go, the Lands Department, Territory Development Department, Housing Authority and district office are still discussing how the project should be carried out. A spokesman for the Housing Authority said compensation and rehousing for the villagers had to be sorted out before clearance started. Tai O has a population of more than 3,000.
