This publication, ""Standard Guidelines for the Design of Urban Subsurface Drainage, Standard Guidelines for Installation of Urban Subsurface Drainage, Standard Guidelines for Operation and Maintenance of Urban Subsurface Drainage"", contains three standards that are independent documents intended to complement the ""ASCE Urban Subsurface Drainage Manual."" The first standard (ASCE 12-92) provides guidelines for design of urban subsurface drainage and covers such topics as site analysis, system configuration, filters and envelopes, hydraulics and hydrology, structural considerations, and materials. The next standard (ASCE 13-93) presents guidelines for installation of urban subsurface drainage and covers such subjects as site inspection, soil erosion, excavation, foundation preparation, and inspection of materials, equipment, and construction. The final standard (ASCE 14-93) provides guidelines for operation and maintenance of urban subsurface drainage and covers such topics as design criteria, maintenance procedures, safety, water quality, inspection, and rehabilitation.
