Design and Construction of Urban Stormwater Management Systems - MOP FD-20

This Manual of Practice for the Design and Construction of Urban Stormwater Management Systems updates relevant portions of ASCE/WEF Manual of Practice No. 37, "Design and Construction of Sanitary and Storm Sewers," published in 1969. This update was undertaken by the Urban Water Resources Council of ASCE for several reasons:

  1. ASCE and WEF published, in 1982, a revised Manual of Practice (No. 60) on "Gravity Sanitary Sewer Design and Construction," which did not address storm drainage.

  2. There have been a number of changes in the field of urban storm drainage, including (1) the virtually universal use of the microcomputer for data organization and analysis, and (2) the increasing importance of designing urban storm drainage systems for the control of runoff quality as well as quantity.

This Manual is intended to aid the practicing engineer by presenting a brief summary of currently accepted procedures. It is not intended to substitute for engineering experience and judgment, nor is it a replacement for more detailed standard texts and references in the field.

The Manual recognizes that the practice of urban storm drainage is dynamic and rapidly changing, with new techniques, materials, and equipment continuously being introduced, and emphasizes that practitioners in the field must constantly be aware of new developments and modify their practice accordingly. The UWRRC invites comments and recommendations for improvement for possible inclusion in future editions.
