加拿大人均年径流量居世界第9位,约82665m~3,为中国人均年径流量约2282~3的36倍。有着如此丰富水量的国家,仍然从社会、经济、制度、工程、运行等各方面采取措施,加强城市用水的综合管理。加拿大城市用水管理的经济措施主要体现在水费政策方面。在传统的费率形式如统一费率、固定费率、递减费率和递增费率的基础上,加上考虑基本生活需水量(为不能支付正常费率的用水户提供最起码的生活需水量或是最少量的水)以及灵活多变的季节性费率、超额用水费率和排污附加费率。加拿大城市的平均水费在0.5-1.5加元/m~3之间,其
The per capita annual runoff of Canada ranks 9th in the world, about 82665m ~ 3, which is 36 times of the annual per capita annual runoff of about 2282 ~ 3 in China. Countries with such a large amount of water still take measures from the social, economic, institutional, engineering and operational aspects to strengthen the integrated management of urban water use. Economic measures for urban water management in Canada are mainly reflected in the water policy. Based on traditional rates such as flat rates, fixed rates, reduced rates and incremental rates, the basic living needs to be taken into account (taking into account minimum living needs of water users who can not afford normal rates) Or the minimum amount of water) as well as flexible seasonal rates, excess water rates, and sewage surcharge rates. The average water fee in Canadian cities is between 0.5-1.5 CAD / m 3
