摘要

Different types of failures of urban storm drainage and combined sewer systems need to be distinguished: structural, hydraulic and environmental. The respective failure diagnoses are based on sewer surveys and on analysis with a simulation model, such as SWMM, to evaluate the flooding and pollution load discharged into receiving waters. Rehabilitation may include repair, reinforcement, replacement, flow attenuation or reduction, overflow management, treatment, etc. The U.S. Environmental Protection Agency has established requirements for good management and rehabilitation of drainage systems.
