ASCE 45-16, 46-16, 47-16

Prepared by the Urban Drainage Standards Committee of the Standards Development Council of the Environmental and Water Resources Institute of the American Society of Civil Engineers

This single-volume set of three standards establishes guidelines for the design, installation, and operation and maintenance of urban stormwater systems. ANSI/ASCE/EWRI 45-16 provides guidance for the design of urban stormwater systems, covering topics such as site analysis, system configuration, hydrology, hydraulic design, nonstructural considerations, structural design, and materials. ANSI/ASCE/EWRI 46-16 presents guidelines for the installation of these systems and discusses subjects such as contract documents, preconstruction site inspection, construction, and inspection. ANSI/ASCE/EWRI 47-16 provides guidelines for the operation and maintenance of these systems, including operation and maintenance plans, water quality, periodic inspection, and maintenance. In this new edition, which supersedes the 2005 standards, numerous technical details have been added, drawn from original, practical research, particularly in the areas of hydrology, hydraulic design, and structural design. Throughout these standards, new references have been added and others updated.

Standard Guidelines for the Design, Installation, and Operation and Maintenance of Urban Stormwater Systems offers comprehensive guidance for the collection and conveyance of surface stormwater. The three standards are useful in applications such as airports, roads, and other transportation systems, as well as industrial, residential, and recreational areas. Engineers and planners working with urban stormwater systems, along with the owners of such systems, will find these updated standards to be a valuable resource.
