本幻灯片概述了奥兰多公用事业委员会（Orlando Utilities Commission）的一个项目的信息，该项目有以下目标:执行和学习国际水协会/美国水务工程协会（IWA/AWWA）推荐的新水审计方法；利用新的独立审计帮助支持对媒体和水管理区的回应；以及确定泄漏调查的必要性。项目范围包括:AWWA/IWA推荐的方法；系统输入流量测试（WTP仪表）；用户仪表精度分析；分析任何账单数据处理错误；评估各种未测量用途； 确定绩效指标（实际损失和表观损失）；“自下而上”夜间流量分析和压力阶跃试验；以及，中断和背景估计（BABE）成分分析。

This slide presentation outlines information on a project by the Orlando Utilities Commission that had the following objectives: to perform and learn the new International Water Association/American Water Works Association (IWA/AWWA) recommended water audit methodology; to use the new independent audit to help support responses to media and water management districts; and, to determine the need for a leak survey. The project scope includes: AWWA/IWA recommended methodology; flow testing of system inputs (WTP meters); analysis of customer meter accuracy; analysis of any billing data handling errors; assessment of various unmeasured uses; determination of performance indicators (real and apparent losses); "bottom-up" night flow analysis and pressure step test; and, Break and Background Estimates (BABE) component analysis.
