運用大數據協助提昇水安全計畫執行效能

台水為確保從水源至用戶水質安全，於107年9月參考世衛組織（World Health Organization, WHO）2004年水安全計畫手冊、WHO飲用水水質準則及國際自來水協會（International Water Association, IWA）波昂安全飲用水憲章，開始推動水安全計畫（Water Safety Plan, WSP），取水質預警系統（Alarm Data Transfer System, ADTS）及1910客服系統大數據，計算供水系統水質總風險，接續評估因應策略及以坪頂給水廠供水系統做為模擬案例，導入專家系統修訂推動架構，透過小組腦力激盪（Brainstorming Technique, BT），循序漸進、抽絲剝繭並持續檢討改善。試辦證實運用大數據計算水質風險優於手工統計分析水質風險，對節省人力及預防水質超標具正面效益，台水目前已全面推動。

A methodology to prioritize the water supply system (WSS) upgraded by water safety plan (WSP) is described. It is based on the risk management and water quality testing to assess safe water supply strategy. The main aim of this study tries to effectively improve the phenomenon of water safety in Taiwan. Pingding, the south-western WSS in Taiwan, was chosen as the case study because the granule of aluminum of source water in this area were easily beyond the regulation threshold. Besides, this district was frequently hit by high turbidity events during raining seasons that always result in overloading for water treatment processes and then occasionally run customer to doubt or complaint the tap water quality. Compared with the traditional way of World Health Organization (WHO), the methods in this research attempted to simplify the complication of risk matrix by deriving big data from ＂Customer Service System (CSS)＂ and ＂Alarm Data Transfer System (ADTS)＂. The methodology developed in this research not only provides the systematic model to follow but also reduces the cost of labor and time effectively. In fact, it has made a valuable contribution to the practical tasks. The original Total Risk Score (TRS) was reduced from 47 to 33 by conducting Taiwan Water Corporation (TWC) WSP. The WSP ten-step guideline shows that the WSP has achieved considerable results. It is worthwhile to follow the case study as the main body and promote it to the whole company in TWC.
