Three Standards are combined in a single volume to provide guidelines for design, installation, operation, and maintenance of urban subsurface drainage systems. ASCE/EWRI 12-05 provides guidelines for the design of urban subsurface drainage systems, covering topics such as site analysis, system configuration, filters and envelopes, hydraulics and hydrology, structural considerations, and materials. ASCE/EWRI 13-05 presents guidelines for installation of urban subsurface drainage and discusses subjects such as site inspection, soil erosion, excavation, foundation preparation, and inspection of materials, equipment, and construction. ASCE/EWRI 14-05 provides guidelines for operation and maintenance of urban subsurface drainage, including design criteria, maintenance procedures, safety, water quality, inspection, and rehabilitation.
These Standards, completely revised, are intended to complement ASCE Manual of Practice 95, Urban Surface Drainage.
