Our campus, which occupies an area of 138 hectares, over 60% of which is covered in vegetation, is both the largest and greenest university campus in Hong Kong.\u00a0 Protecting such a large area is not easy.\u00a0 Irrigation alone is a significant challenge.\u00a0 Nevertheless, it is a challenge which the University is determined to meet fully.<\/span><\/p>\n

CUHK has been monitoring its water use since 2005.\u00a0 Between 2005\/06 and 2024\/25, per-capita consumption of potable water declined by 29%.<\/span><\/p>\n

Water is used on campus for irrigation, for cleaning, for washing and showering, for cooking and preparing drinks, and to fill the University’s swimming pool.\u00a0 CUHK has implemented a range of strategies to conserve potable water in its operations.<\/span><\/p>\n

As always, these efforts are not limited to operational practices and infrastructural improvements.\u00a0 High emphasis is placed on raising the awareness of the university community, through annual hostel water-saving competitions organised by colleges, and events and seminars by student groups.<\/p>\n

\"\"<\/td>\nThe completion of a water treatment plant in 2012 enables the lake to supply the University’s water needs beyond irrigation.\u00a0 The lake can supply up to 1,100 cubic metres of water each day (after treatment) for campus irrigation, cleaning and cooling systems.<\/span><\/p>\n

Weiyuan Lake is now more than just a scenic campus attraction.\u00a0 It is also part of the University’s life support system, and we are committed to taking good care of it.<\/td>\n<\/tr>\n
