Mayor Park Heong-joon: “Make Busan’s Water Supply the National Standard for Public Service Innovation” — Busan Water Authority Hosts AI Transformation (AX) Strategy Forum

내용

The Busan Metropolitan City Water Authority (hereinafter referred to as “the Authority”) announced that it will unveil “Sangsu iN (tentative name),” an AI Agent developed in-house based on water supply operational data, and disclose its direction for AI transformation (AX) in the water supply sector.

An AI Agent refers to an artificial intelligence system that works autonomously and assists with tasks.

The announcement was made at the “Busan Water Authority AI Transformation (AX) Strategy Forum,” held today (February 27) at 9:30 a.m. in the main conference hall on the 10th floor of the Authority’s headquarters.

The forum was organized to share AI transformation (AX) strategies in the water supply sector and to discuss the structure and applicability of the self-developed AI Agent. The program proceeded in the following order: ▲ introduction of the Data Analysis Task Force (TF) ▲ introduction of the AI Agent “Sangsu iN” ▲ presentation of the AI transformation roadmap.

“Sangsu iN,” unveiled at this forum, is the first case in the nation in which a local government independently designed and developed the structure of an AI Agent and applied it directly to water supply operations.

Unlike existing administrative support cases based on large language models (LLMs), this system is distinguished by its implementation of an agent architecture centered on the operational context and practical experience of water supply services.

Through this forum, the Authority announced its strategy to foster the water supply sector as a leading hub for public AI transformation (AX). AI transformation (AX) goes beyond simply introducing AI technologies; it is a strategy to systematically connect operational data and work systems in the water supply sector in order to enhance efficiency and responsiveness.

To support this initiative, the Authority launched an internal dedicated organization, the Data Analysis Task Force (TF), in January of this year.

The AI Agent “Sangsu iN” introduced at the forum is based on Retrieval-Augmented Generation (RAG), which links internal water supply documents and operational data. Rather than serving merely as a document-generation or question-and-answer system, it is designed as a participatory AI system directly utilized within the workflow of water supply operations. Its key feature is a structure that assists and supports water supply tasks.

The Water Authority operates 24 hours a day as a core urban infrastructure and represents a data-driven administrative field where real-time data and facility histories are continuously accumulated.

The Authority has presented the following as the core directions of its AI transformation (AX) initiative: ▲ systematizing field operational experience ▲ strengthening data-based work support ▲ automating and standardizing repetitive tasks ▲ advancing AI capabilities centered on internal expertise. Through these efforts, it aims to establish a “work-centered AI” model rather than a technology-centered one.

Mayor Park Heong-joon stated, “The water supply system is a core urban infrastructure that cannot stop for even a single moment and is the most fundamental public service directly connected to citizens’ daily lives.” He added, “The introduction of this AI Agent goes beyond the application of a new technology; it marks a starting point for fundamentally innovating water supply administration by intelligent utilization of accumulated operational data and field experience.”

He further emphasized, “By systematically connecting the vast data and know-how accumulated in the field, we will support faster and more accurate decision-making, cultivate the water supply system as a leading model for public AI transformation (AX), and lay the foundation to drive innovation in public services nationwide.”
