一、前言本文就自来水系统规划的决策问题,以自来水设施改良的必要性为依据,介绍自来水系统的可靠性分析方法以及克罗拉多州Bouldel市供水行业对该方法的运用实例。二、自来水设施规划决策中对供水可靠性的设想自来水系统的供水可靠性是供水者向用户提供服务的具体指标。这种可靠性若从水源设施上来看,主要是受水文条件稳定性以及水资源利用与开发的影响;若从引水、净水、配水设施上看,主要是受各种设施发生正常运行或破损的影响。另外,从供水可靠性看,它是以用户对供水设施的可靠性为依据的,由供水者各自
I. INTRODUCTION This paper describes the decision-making of tap water system planning based on the necessity of improved tap water facilities and introduces the reliability analysis of tap water systems and the use of this method by the water supply industry in Bouldel, Colorado. Second, water facilities planning and decision-making on the reliability of water supply water system water supply reliability is the water supply to provide users with specific indicators. This reliability is mainly affected by the stability of hydrological conditions and the utilization and development of water resources when viewed from the water source facilities. If the water diversion, clean water and water distribution facilities are concerned, the reliability is mainly caused by the normal operation or damage of various facilities Impact. In addition, from the reliability of water supply, it is based on the reliability of users of water supply facilities as the basis, by the water supply their
