Most of the wastewater treatment facilities in the upstream areas of dams in Korea are small and scattered and the local governments of these areas are financially very poor as well. Owing to these characteristics, though they directly impact the quality of water resources, operations and management of these facilities have been non effective. So, in this research, Korea Water Resources Corporation (K-water) has tried to integrate operations and management (O&M) of wastewater treatment facilities in these areas to maximize operating efficiency. Although there have been some difficulties measuring effects of an integrated system, we could see many positive consequences including operating cost reduction, effluent quality and process efficiency elevation, and customer service improvement in the centralized O&M.
