住宅用户在哪里用水？如何在高度可变的背景用水情况下准确测量住宅节水项目的微妙影响？这些问题对水供应商和规划者至关重要，他们经常被要求预测水需求、系统可靠性，并确定满足这些需求所需的大规模资本项目的要求。科罗拉多州博尔德市开发了一种新的数据收集技术，使供水商不仅可以精确测量居民用水，还可以量化任何保护计划所带来的实际节水。 本文描述了在博尔德郊区社区进行的一项试点研究，该研究使用一个连接在住宅水表上的数据记录器生成分类数据。本研究确定了九种不同的住宅用水类别:厕所、淋浴、浴缸、洗碗机、洗衣机、灌溉、水龙头、漏水和游泳池。还创建了一个计算机化的客户信息系统（CIS），以帮助选择研究小组。

Where are residential customers using their water? How can subtle effects of residential water conservation programs be accurately measured against highly variable background water use? These questions are of critical importance to water providers and planners who are routinely called upon to project water demands, system reliability and determine the requirements for massive capital projects needed to meet these demands. A new data collection technique developed in Boulder, Colorado, makes it possible for water providers to not only precisely measure residential water use, but also to quantify the actual water savings effected by any conservation program. This paper describes a pilot study conducted in a suburban community in Boulder that uses a single data logger attached to residential water meters to produce disaggregated data. Nine distinct residential water use categories were identified for this study: toilets, showers, bathtubs, dish washers, clothes washers, irrigation, faucets, leaks, and swimming pools. A computerized customer information system (CIS) was also created to aid in the selection of the study group.
