台灣地區水資源開發日益困難，為降低缺水風險，提升水資源利用效率，除持續推動自來水輸配水管線減漏技術外，如何加強簡易自來水管理業務績效及提升自來水事業淨水效能，便成為極重要的一環。 為達成前揭政策目標，本署於102-104年度辦理地方政府簡易自來水管理業務查核及管理操作示範觀摩；於104年度「提升淨水場用水效能策略之先期研究」，針對淨水場造水效能、水質處理及能耗三面向，提出操作及管理效能評估之指標。 本計畫將延續以往研究成果，除賡續辦理簡易自來水管理業務查核及維護管理技術提升外，將試辦自來水淨水場操作及管理效能指標應用於國內自來水事業之評核作業，並辦理簡易自來水之輔導與人員訓練；另有鑑於自來水輸配水管線水壓管理對於降低漏水率相當重要，因此本計畫亦將以馬祖地區為案例檢討水壓管理技術運用於自來水供水管網之降低漏水率成效，爰提本計畫。

To minimize the risk of water shortage and improve the efficiency in the use of water resources, it is necessary to enhance the operational performance of water utilities. Therefore, this study is aimed to to establish appropriate management indicators to evaluate water-use efficiency, water quality, energy efficiency in water treatment plants (WTPs) in Taiwan area. The materials in management and operation in WTP have been collected for this study, and the corresponding management indicators also have been established. Ten WTPs, including Gongguan, Longtan, Pingien, Baoshan, Hsinchu Second, Nanhua, Wushantou, Gonyuan, Linnei and Ronghu) have been chosen as demonstration sites to audit their management indicators. Evaluation of management indicators on three WTPs, including Gongguan, Longtan and Hsinchu Second, has been finished. The results have shown that averaged water productivity of WTPs with the capacity of water production more than 100,000 CMD is in the range from 87.60% to 99.68%. The quality of finished water in these WTPs completely complies with the drinking water standard, but the quality of finished water in most WTPs cannot comply with internal standard in terms of the residual turbidity and aluminum. The energy saving ratio per unit of water production is in the range from -6.77% to +28.7% for WTPs, and the ratio presents a negative value because of high percentage of overdue electromechanical appliances or extraordinary water supply to other areas. In addition, the demonstration in managing small water treatment systems as well as the training program in the operation of small water treatment plant has been conducted. This project also has periodically assisted the Water Resources Agency (WRA) in the maintenance of the membrane filtration module (also called IS Water) located at Hengshan elementary school in New Taipei City and Heping junior high school in Taichung City. During continuous operation, the effluents from two IS Water modules comply with the standard of drinking water quality without post-chlorination. On the other hand, a small water treatment plant equipped with a remote monitoring system closed to Changhu elementary school in Yunlin County has been chosen to evaluate the feasibility of remote monitoring technique and its effectiveness in managing and maintaining small water treatment plant. The remote monitoring system has been proven improving the management efficiency of small water treatment plant under periodical facility maintaining. Meanwhile, a water quantity and pressure management system in drinking water distributions in Matsu area has been established, and then the necessary field trial in Fuxing and Jieshou districts and its effectiveness have been examined. The water quantity and pressure management system has ability to real-time record the water quantity and pressure values and automatically analysis the averaged minimum flow during midnight. It can assist Matsu WTP in understanding the behavior of water consumption and water leaks in different drinking water distributions as well as real-time controling water quantity and pressure based on alarm system.
