北京属资源型重度缺水地区,截至2015年底,北京的汽车保有量已经突破了570万辆,清洗一辆汽车用水约为0.16吨,若以570万辆汽车每周清洗一次计算,北京市每年的洗车用水量将突破4700万吨,相当于抽干了20余个昆明湖。为了解决日益显著的用水危机,政府希望通过价格手段控制洗车业用水量,进而通过水价杠杆撬动每吨仅1元钱的中水(再生水)的广泛利用。然而实际情况却不容乐观,
Beijing is a resource-intensive and water-scarce region. As of the end of 2015, Beijing’s car ownership has exceeded 5.7 million cars and the water used to clean a car is about 0.16 tons. If 5.7 million cars are cleaned once a week, Beijing annually Of the car wash water will exceed 47 million tons, equivalent to pumping more than 20 Kunming Lake. To address the growing water crisis, the government hopes to control the amount of water used in the carwash industry through price controls, thereby leveraging the widespread use of water (reclaimed water) at just $ 1 a tonne through price leverage. However, the actual situation is not optimistic,
