我国水资源总量较大,但人均占有量相对较少,淡水资源人均占有量为世界人均水平的1/4,排在世界第121位,为13个最贫水国家之一。从2001年至2013年的13年时间里,水费价格从未调整,供水成本逐年上升,亏损额逐年增加。为了保证供水能力和质量,不断的加大资金投入,兴建新型水厂,对老旧的水厂及管网进行维护,提升污水处理能力,加大二次供水改造工程,诸多原因导致供水企业代政 The total amount of water resources in our country is larger, but the per capita amount is relatively small. The per capita possession of freshwater resources is 1/4 of the world average, ranking the 121st in the world and one of the 13 poorest countries. In the 13 years between 2001 and 2013, the price of water has never been adjusted. The cost of water supply has been increasing year by year, and the amount of losses has been increasing year by year. In order to ensure water supply capacity and quality, continue to increase capital investment, the construction of new water plants, the old waterworks and pipe network maintenance, improve sewage treatment capacity, increase the secondary water supply reconstruction project, many reasons lead to the generation of water supply enterprises Politics
