本文的主题是2001年11月完成的一项市场渗透研究。总体而言，这项研究实现了四个主要目标:从居民客户那里收集有关节水相关态度和行为的数据；量化住宅和选定非住宅市场部门使用硬件和设备的水的类型和饱和度；将研究结果与之前两项研究的结果联系起来，以估算标准效率固定装置与高效固定装置的更换率；此外，评估与夹具和器具更换相关的剩余保护潜力。 这些目标是通过电话和现场调查、收集数据的统计分析以及其他来源的相关数据分析来实现的。EBMUD保留了水资源工程公司（WRE）的服务来设计和实施该研究，并提供了客户信息数据库和EBMUD人员进行数据收集。项目任务包括准备研究设计、培训项目人员进行数据收集、开发数据收集系统和客户外联材料、通过电话和现场调查进行数据收集，以及准备一份研究报告，展示研究结果和推论。 2001年水资源保护市场渗透研究的综合研究报告包括研究设计说明、调查结果列表，以及对固定装置更换率和保护潜力的分析。本文不是总结研究报告，而是描述了设计和实施研究的过程，同时强调了后勤问题和经验教训，并描述了关键发现和分析，以及对保护项目设计和评估的影响。包括表格、数字。

The subject of this paper is a market penetration study completed in November of 2001. The study, by and large, achieved four major objectives: collect data from residential customers regarding water conservation related attitudes and behavior; quantify the types and saturation of water-using hardware and appliances in residential and selected non-residential market sectors; relate study findings to those of two previous studies in order to develop estimates of the rate of replacement of standard efficiency fixtures with high efficiency fixtures; and, assess the remaining conservation potential associated with the fixture and appliance replacement. These objectives were accomplished through telephone and site surveys, statistical analysis of collected data, and analysis of pertinent data from other sources. EBMUD retained the services of Water Resources Engineering, Inc. (WRE) to design and implement the study and provided a database of customer information and EBMUD personnel to conduct data collection. Project tasks included preparing a study design, training of project personnel for data collection, developing data collection systems and customer outreach materials, conducting data collection through telephone and site surveys, and preparing a study report presenting findings and inferences. A comprehensive study report on the 2001 Water Conservation Market Penetration Study contains a description of the study design, tabulations of findings, and an analysis of fixture replacement rates and conservation potential. Rather than summarize the study report, this paper describes the process of designing and implementing the study, while highlighting logistical problems and lessons learned, and describes key findings and analysis with implications for conservation program design and evaluation. Includes tables, figures.
