由ASCE环境和水资源研究所标准发展委员会城市排水标准委员会编制。这套由三个标准组成的单卷标准为城市地下排水系统的设计、安装、运行和维护制定了指南。ANSI/ASCE/EWRI 12-13提供了这些系统的设计指南，包括现场分析、系统配置、排水包壳、水力学和水文学、结构考虑和材料。ANSI/ASCE/EWRI 13-13侧重于安装，并检查现场调查、安装程序和检查。ANSI/ASCE/EWRI 14-13提供了城市地下排水的运行和维护（O&M）指南，包括运行和维护计划、安全、水质、检查、维护和修复。这个新版包含了主要的州- 关于不同类型排水沟（包括排水管、集料排水沟、土工织物排水沟、土工网和土工复合排水沟）水力的最新标准12。在这些标准中，添加并更新了参考文献。这三个标准共同为工业、商业、住宅和娱乐区地下排水的收集和输送，以及机场、道路和其他交通系统等应用提供了全面的指导。从事地下排水系统工作的工程师，以及此类系统的所有者，将发现这些更新的标准是一种宝贵的资源。

Prepared by the Urban Drainage Standards Committee of the Standards Development Council of the Environmental and Water Resources Institute of ASCE.This single-volume set of three Standards establishes guidelines for design, installation, and operation and maintenance of urban subsurface drainage systems. ANSI/ASCE/EWRI 12-13 provides guidelines for the design of these systems and covers site analysis, system configuration, drain envelopes, hydraulics and hydrology, structural considerations, and materials. ANSI/ASCE/EWRI 13-13 focuses on installation and examines site investigation, installation procedures, and inspection. ANSI/ASCE/EWRI 14-13 provides guidelines for operation and maintenance (O&M) of urban subsurface drainage, including O&M plans, safety, water quality, inspection, maintenance, and rehabilitation. This new edition contains major state-of-the-art updates to Standard 12 regarding the hydraulics of different types of drains, including drain pipes, aggregate drains, geotextile drains, and geonets and geocomposite drains. Throughout these Standards, references have been added and updated.Together, the three Standards offer comprehensive guidance for the collection and conveyance of subsurface drainage waters in industrial, commercial, residential, and recreational areas, as well as for applications such as airports, roads, and other transportation systems. Engineers working with subsurface drainage systems, along with the owners of such systems, will find these updated standards to be a valuable resource.
