中文摘要 <摘 要>

自來水營運成本包括水源成本及相關的處理(與供應)成本,台灣省自來水股份有限公司第六區管理處負責供應台南縣市地區並支援嘉義及高雄地區之自來水,其水源主要取自曾文水庫及南化水庫,在曾文水庫系統之原水成本遠高於相關處理成本,為提高營運績效,應採行較低成本之取水策略。由於曾文-烏山頭水庫系統現行之運用規定係由水源管理機關制定,主要依據曾文-烏山頭水庫運用規線分配各標的水量,唯若有不足時,則酌量允許超量取水,再由移用標的付給被移用標的一筆補償費。曾文-烏山頭水庫運用規線規定中分配給家用及公共給水標的之用水,依據每旬規線分配水量,南水局允許可暫存20%,或超用10%以內水量,該暫存或超用水量可於水文年度結束前互相沖銷。因此,如何善用此一特性,配合南化水庫系統的運作,以配合台南地區現地用水變動及降低營運成本,值得深入探討。

本研究因應前述暫存和超用水量可相互沖銷的規定,分就各項影響取水成本之規定,在減少取水成本支出考量下,擬訂八種不同取水策略,經由水量調度模擬,探討較經濟的豐、平、枯水年的暫存水量及超用水量時機。

研究結果顯示,不論豐、平、枯水年,在每年6月至10月豐水季期間,暫存20%分配水量於曾文水庫,在翌年1月起之枯水季再以超用10%水量方式,提取原先暫存的水量,可減少台灣省自來水股份有限公司第六區管理處一部份營運支出,也可減低枯水季的缺水風險。

英文摘要

The operating cost of metropolitan water supply includes the costs of raw water and related treatment and supply. The 6th Branch of Taiwan Water Corporation (TWC6B) is responsible for supplying water to Tainan metropolitan and supporting part of requirements of Chiayi and Kaohsiung districts. TWC6B withdrawals raw water primarily from Tsengwen-Wushantou and Nanhua reservoirs. The cost of raw water which withdrawals from Tsengwen-Wushantou reservoir system is significantly higher than its treatment cost. In order to raise the operating efficiency and benefit, the authority of TWC6B may adopt an appropriate withdrawal strategy to lower operating cost.

The operation rules of Tsengwen-Wushantou reservoir system is established by the Ministry of Economic Affairs (MOEA). Water stored in reservoir is allocated to each purpose according to the operation rule curves. If the water allocated is less than actual requirement, it allows the purpose to overtaking the insufficient amount of water from reservoir or transfer required water from other purposes. However, the transferred water should be compensated.

Tsengwen-Wushantou reservoir distributes water to domestic and public water supply according to the rule curves in every ten-day period. The Southern Region Water Resources Office of Water Resources Agency, MOEA, allows up to 20% of the allocated water to be deposited in the reservoirs or up to 10% to be overused for water supply. The deposited or overused water can be balanced off before the end of a hydrologic year. Therefore, it is worth of detailed study to lower the operation cost by taking advantage of this feature in coordinating the withdrawal strategy from Tsengwen-Wushantou and Nanhua reservoir systems to cope with the variation of water requirements.

This research devised 8 withdrawal strategies to reduce the total operating cost by considering the deposited and overused water which can be balanced off, also the compensated cost of transferred water. Through the simulation of water supply, this research investigated the most economical strategy of the proper timing and periods of depositing water and overusing water during wet, normal and dry hydrologic years. The simulated results pointed out that the most economical strategy is to deposit 20% allocated water to Tsengwen-Wushantou reservoir from June to October and overuse 10% of deposited water in the following dry season no matter in wet, normal or dry years. This strategy promised the reduction of operation expenses of TWC6B and lowered the risk of lack water during dry season.
