本文讨论了国际开发署资助的拉丁美洲农村供水项目的若干技术问题。它专注于重力系统水项目，无需过滤或抽水。绝大多数援助项目提供塑料管、重力流系统，并将其分配到家庭庭院水龙头，以及用于处理生活垃圾的厕所。涵盖的主题包括供水来源、水质、重力系统技术、成本、施工质量和系统性能，以及规模和可持续性。尽管报告的数据来自援助项目，但讨论的技术与其他机构资助的类似规模的项目几乎没有什么不同。

This paper discusses selected technology issues of Agency for International Development funded rural water supply projects in Latin America. It focuses on gravity-system water projects without filtration or pumping. The great majority of AID projects provide for plastic pipe, gravity flow systems with distribution to household yard taps, and with latrines for sanitary waste disposal. Topics covered include water supply sources, water quality, gravity system techniques, costs, construction quality and system performance, and sizing and sustainability. Although the data reported come from AID projects, the technologies discussed differ little from projects of similar size funded by other agencies.
