在过去十年中，IWA水损失工作组成员开发了一种系统的实用方法，用于非收入水及其组成部分的技术管理，（自2002年以来）在这些计算中越来越多地使用95%的置信限。目前的水损失特别工作组最近为自己设定了一个目标，即开发一种快速实用的方法来计算经济干预（用于主动泄漏控制，以确定未报告的泄漏和爆裂）和短期经济泄漏水平。本文概述了一个快速和实用的方法来评估经济干预频率（和相关的预算和体积参数）的主动泄漏控制政策的基础上定期调查。计算基于三个关键参数：未报告渗漏的自然增长率、水的边际成本和干预成本。希望这将鼓励目前没有采取主动泄漏控制的公用事业公司采取持续的基本主动泄漏控制政策，该政策可以简单地证明为符合其自身情况的经济性。
During the last decade, IWA Water Losses Task Force members have developed a systematic practical approach to the technical management of non-revenue water and its components, with (since 2002) increasing use of 95% confidence limits in these calculations. The current Water Losses Task Force has recently set itself an objective to develop a quick and practical method for calculating economic intervention (for active leakage control to locate unreported leaks and bursts), and short-run economic leakage level. This paper outlines a quick and practical method for assessing economic intervention frequency (and associated budgetary and volumetric parameters) for an active leakage control policy based on regular survey. Calculations are based on three key parameters: natural rate of rise of unreported leakage, marginal cost of water, and cost of intervention. It is hoped this will encourage Utilities that do not currently undertake active leakage control to adopt an ongoing basic active leakage control policy which can be simply demonstrated as being economic for their own situation.
