在国家科学基金会的资助下，Roy F. Weston公司开发了一个水管理（WATMAN）模型。WATMAN模型为用户提供了一个工具，根据水源和需求的组成，分析各种综合供水系统替代方案，包括再生水分配。在未来为社区或地区制定任何长期水管理计划时，水的再利用将是一个重要的考虑因素。沃特曼模型对于分析水资源再利用管理计划特别有用。

With a grant from the National Science Foundation, Roy F. Weston, Inc. has developed a water management (WATMAN) model. The WATMAN model provides the user with a tool to analyze various integrated water supply system alternatives, including reclaimed water distribution, depending on the composition of sources and demands. Water reuse would be an essential consideration in the future in developing any long-term water management plan for a community or a region. The WATMAN model is particularly useful for analyzing water reuse management plans.
