7 cities : < 2.0 low Price Wasting water 0.1 ，Water Resources Price were remain unchanged in 80％ investigated cities ， 80％的调研城市未对水资源费进行过调整

30 结论 Conclusions 北方地区的用水量已经保持在一个比较稳定的状态。
The water supply volume in northern regions has reached a stable stage. It will grows at a slower pace or even witness a decline in the coming several years. 北方地区供水能力闲置会造成比较大的资源和资金的浪费，而关闭自备井与否是影响未来投资额的一个重要因素。 The unused water supply facilities caused huge waste of resources, and shutting down the self-built wells is a key factor which will influence the future investment. 管网投资将会是未来投资的主要去向。 More and more investment will go to pipe network in the future. (To be continued)

31 结论 Conclusions 目前设计的这套供水企业绩效评价系统已经具备了中国初步应用的可能性，但是仍然存在部分指标有待修改及完善。
The designed performance benchmarking system for water utilities could be preliminarily applied in China. However, some indicators are also waiting for improvement. 绩效分析的结果显示：企业运行效率偏低，服务质量不高；仍然存在部分供水企业负债运营。 Performance analysis result shows: WSE has low operational efficiency and service quality and there are still some WSE in indebted operation. 关键问题：水源污染问题严重；地下水过度开采；水价偏低。 Key issues: water pollution is serious; groundwater is excessively exploited; tariff is low. (To be continued)

32 建议 Suggestions 科学预测需水量，避免供水规划脱离实际。
More scientific measures must be adopted to estimate water demand to avoid high prediction. 建议未来应加强自备井的管理，并适当关闭部分自备井。 In the future, the management of self-built water must be strengthened especially self-built wells, which trigger series of problems affecting the eco-environment, water quality and effective management; 建议今后应加大管网更新改造力度，改善用户端的出水水质。 Efforts should be strengthened on upgrade and replacement of pipe networks so as to improve the quality of water at the end of consumers. (To be continued)

33 建议 Suggestions 理顺政府与企业的关系。
Rationalizing the relationship between the government and enterprises. The initial step is to further transfer government functions. The second step is to improve decision-making mechanism. Third, it is also necessary to establish the external supervision system. 供水企业应提升企业管理水平。 WSE should promote their management level including improving operation efficiency, service quality and collection ratio of tariff, reducing cost and consummating statistic and management system.
