Prepared by the Urban Drainage Standards Committee of the Water Resources Standards Council of the Codes and Standards Activities Committee of ASCE; and the Technical Activities Committee of ASCE.

Urban Subsurface Drainage provides information and direction for solving subsurface drainage problems in urban areas. It includes detailed background information to help with the planning, design, construction, and operation and maintenance of urban subsurface drainage systems. Discussion is designed to lead to sound proposals with better overall results and the prevention of expensive repair and reconstruction of infrastructure.

Topics include:

• planning;
• system configuration, including collection system components;
• hydraulics and hydrology;
• drain envelopes;
• structural design, including dead loads, live loads, and pipe behavior;
• pipe materials;
• construction issues, including contract documents, permits, and installation methods; and
• operation and maintenance

MOP 95 should be used in conjunction with the most recent edition of Standards ASCE 12, 13, and 14, which present standard guidelines for the design, installation, and operation and maintenance of urban subsurface drainage. Engineers working with subsurface drainage systems, along with the owners of such systems, will find this Manual of Practice to be a valuable reference.
