- Abstract:
- The sewer is an important infrastructure for sewage and rainwater drainage. Unfortunately, sewers are undergoing aging and deterioration due to the rapid development of urban, increase of population density and unsuitable drainage method. The existence of structural defect, e.g. fracture and deformation, and functional defect, e.g. root and encrustation, have caused cities vulnerable to be effected by urban waterlogging, sewage overflows and ground subsidence. Sewers operation and maintenance management has been neglected for a long time, i.e. the problems caused by deteriorating drainage pipes were responded passively, resulting in high cost of emergency repairs and ill-effects. Since the implementation of the water environmental governance project and the improvement measures of quality and efficiency in sewage treatment received increasing attention, the construction of pipeline network assets will continue to increase in recent years, and the higher demand of operation and maintenance management capabilities for growing sewers was requested in China. The analysis was conducted with the problems existing in sewer operation and maintenance management and the related recommendations and countermeasures were given. The steps for implementing the improvement of quality and efficiency, aiming at solving the current problem in sewers, i.e. mixed connection of rainwater and sewage sewers, external water infiltration, long-term operating at high water level, etc., were established as well.
