  • Seoul Introduces AI-based Automated Sewage Treatment into Water Reuse Centers by 2030

  • Press Releases SMG 191
    • AI will analyze big data from Water Reuse Centers in real time and make predictions to secure the best water quality
    • Seoul plans to establish an integrated database, central surveillance system, and remote monitoring system by August 2022
    • The new system will guarantee stable management even in the absence of human managers and reduce energy consumption by stopping the unnecessary operation of machines

    SEOUL, SOUTH KOREA, August 18, 2021 – Seoul announced its plan to transform four Water Reuse Centers into AI-based “Intelligent Water Reuse Centers.” To this end, the city will introduce an automated sewage treatment system by 2030. Key data that affects the sewage treatment process will be collected to set up big data so that the AI can analyze the data in real time and automatically manage the water quality. So far, human officials have had to manage the water quality after analyzing the data one by one by themselves. From now on, however, even the monitoring work can be done remotely without worrying about the location.

    To create intelligent Water Reuse Centers, the Seoul Metropolitan Government (SMG) will establish related smart infrastructures in three steps, starting from this year. In step 1 (June 2021 – August 2022), the SMG will construct the “integrated database infrastructure,” “central surveillance system,” and “remote monitoring system.”

    The “integrated database infrastructure” is a server that collects and saves necessary data for the surveillance and management of the whole sewage treatment process. The “central surveillance system” gathers the data collected from the four Water Reuse Centers and keeps a watch on it in one place. Up until now, it was difficult to compare the entire data as each Water Reuse Center operated a disconnected control system. Lastly, the “remote monitoring system” will allow officials to grasp and manage the sewage treatment status through tablet PCs and smartphones regardless of where they are.

    The SMG will advance the system in the second stage (2023 to 2027) and complete building the intelligent Water Reuse Centers by developing an application program in the third stage (2028 to 2030).

    Seoul anticipates that once the system is automated, the efficiency and transparency of the sewage treatment will be maximized, bringing about more systemized quality control. What is notable is that in emergencies—the absence of a person in charge due to the Covid-19 pandemic, for example—there will be no management vacuum in the sewage treatment process.

    Also, the new system is expected to reduce energy consumption and minimize greenhouse gas emissions by cutting down unnecessary operations of machines.

    “By adopting the Ai-based automated system in four Water Reuse Centers in Seoul, we aim to take a leap towards a city with intelligent centers,” said Han Yu-Seok, Director General of Water Circulation Safety Bureau. “We are looking forward to optimized quality control with the maximized efficiency of sewage treatment operations.”
