AN epidemic could break out at Rennie's Mill as residents stand their ground surrounded by rotting refuse, health experts warn. Doctors warn of the threat of gastric illness and advise residents they should not drink well water. Hygiene has been deteriorating as residents move out in the leadup to Tuesday's eviction deadline. Some have dumped rubbish outside their huts while others have piled it in the alleys. Squatters have condemned frequent disruptions of water supply as a Housing Department tactic to force them out. Supply was suspended for about eight hours last Monday. Notices said there were 'works in progress'. Democratic Party legislator Dr Huang Chen-ya warned of an outbreak of gastroenteritis - inflammation of the stomach and intestines - if residents drank well water. 'The Government should not shut off water supply in whatever situation or there could be an epidemic. Public health should always be the utmost concern,' he said. A Housing Department spokesman said it would shut off water and electricity to empty huts to discourage trespassers. The spokesman said officers would continue managing the cottage area until all residents had been moved. Up to Friday, 22 families targeted by Tuesday's clearance had not yet accepted government offers. Resident Lee Ho Yuk, 68, vowed not to concede. 'The Housing Department dares not turn off our electricity or water supply. They want to crucify us but I have to warn them that they will be in great trouble if they do so,' Mrs Lee said. Her family had been offered $500,000 for their three-storey brick house and a public rental unit in Junk Bay, she said. But Mrs Lee wants two flats - one for herself and her husband and the other for their son - and at least $1 million in cash. They were in the first batch of Nationalist refugees to settle in the area 40 years ago. 'Life was primitive when we first moved here. The Government did not even give us a dry crust to eat. We built the paths, huts, and almost everything here on our own,' Mrs Lee said. 'We shall definitely fight to the end if the Government wants to remove us without satisfying our demands.'
