作为澳洲最大的城市,悉尼仍在不断膨胀,每年吸引约5万新移民来此定居。与人口增长趋势恰恰相反,最近几年悉尼市的降水量却在逐年减少。考虑到几年来全球气候变化愈加恶劣,市政府痛下决心投资17亿美元兴建全世界最大的海水脱盐专案。据称,整个系统由堪培拉附近的风能发电场供给,处理好的淡水将进入悉尼市的供水系统,而海盐等剩余残渣则将被排进海水中。 As Australia’s largest city, Sydney is still expanding, attracting about 50,000 new immigrants each year to settle there. Contrary to the population growth trend, precipitation in Sydney has been declining year by year in recent years. Considering the worsening global climate change over the past few years, the city government has made a painful decision to invest 1.7 billion U.S. dollars to build the world’s largest seawater desalination project. Allegedly, the entire system is supplied by a wind farm near Canberra where freshwater treated will enter Sydney’s water supply system and the remaining residue such as sea salt will be discharged into the sea.
