Yes, I think HK water is pretty safe--but it all depends on where you live. We live in an 800-year-old village and the pipes and general plumbing situation are less-than-ideal. We don't drink the tap water. I get stomach problems from drinking it but my husband can drink it without problems (he's from HK and I'm not). Also, the flavor of HK water, to me, tastes like soil. Most of HK's water comes from Guangdong Province and after living in ML China for awhile over the years, I'm not that confident in water that comes from there even though the water may be treated once it arrives in HK. However, having said that, most HK people still boil their water before they drink it--that's why most have a countertop water boiler. But, local people do drink the water with no problems--especially if its boiled. My main issue with water anywhere is chlorine and fluoride so we don't drink tap water at all. Right now we're drinking re-mineralized distilled water and are trying to decide whether to install reverse osmosis as a water filtration system or just go to full distilling.
