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:
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.
