城市供水管网漏损控制潜力研究

在我国备城市普遍缺水的同时,城市供水管网的漏损状况却相当的严重,科学衡量漏损控制的潜力,对于控制漏损和科学地进行城市水资源规划和需求管理非常重要.从技术潜力、经济潜力、社会潜力三方面将城市供水管网漏损控制的潜力进行了分析.提出了以社会最优值作为漏损控制的目标,以社会潜力作为需求管理的依据,同时综合考虑技术潜力和经济潜力.社会最优控制水平和企业的经济漏损控制水平之间有时会存在很大差异.科学的划分政府和企业在控制漏损的义务是非常必要的,如果需要企业的漏损控制水平小于经济漏损水平时政府应该给予一定的补偿,这样才能增加企业控制管网漏损的积极性.

The Potential Leakage Control in Urban Water Supply System Status Quo and its Protection & Management Countermeasures

Many cities suffer from shortage of water,meanwhile the leakage in some distribution systems are very high.It is very im- portant to assess the potential of leakage control in urban supply system when doing water resource plan or managing water supply and de- mand management.This study analyzes technical,economical and social potential of leakage control.It recommends that the social opti- mal level is the target of leakage control and social potential is the base water supply and demand management,as well as technical and economical potential should also be considered to make a comprehensive decision.The social optimal level may be very different with the economical level,so it is important to distinguish the obligation of the government and the water company,If the leakage level is below the economical level,the govenment should compensate the water company to give motivation.
