商业和工业（非居民）节水正成为全美水务设施的一个主要重点领域。有四个因素导致了非住宅保护项目的增长:被要求保护的住宅客户期望商业界也尽自己的一份力量；最近几个州的保护规定要求保护项目包括所有类型的客户；非居民用水相对较小的百分比减少构成了有意义的需求和干旱管理战略； 而非居民用水节约是具有成本效益的。概述了水资源利用的一些主要领域，以及现有的最佳保护技术及其在商业、工业、政府和机构部门的应用。讨论了各州和市政府使用的项目组件，并对非住宅保护的趋势进行了检查。包括7个参考文献和表格。

Business and industrial (nonresidential) water conservation is becoming a major area of emphasis for water utilities throughout the United States. Four factors have led to the growth of nonresidential conservation programs: residential customers who have been asked to conserve expect the business community to do its share as well; recent conservation mandates in several states require that conservation programs include all customers types; a relatively small percentage reduction in nonresidential water use constitutes meaningful demand and drought management strategies; and nonresidential water conservation is cost-effective. Some of the major areas of water use and the best available conservation technologies and their applications in the business, industrial, governmental, and institutional sectors are outlined. Program components used by states and municipalities are discussed, and the trends in nonresidential conservation are examined. Includes 7 references, tables.
