水利署預計於臺南市將軍區分階段興辦臺南海水淡化廠，強化水資源基礎建設，降低缺水風險，以增加區域穩定水源。由於海淡廠等水資源設施之興辦常涉及權益利害關係人之權利、受限者補償等課題，加以目前臺灣的自來水水價過低，興辦成本高於水價的海淡廠更涉及經費分攤、供水對象、使用者付費等議題，這些議題部分涉及既有法規制度，部分涉及資源分配之公平正義，仍須廣泛探討分析其合宜性，研議較妥適之方案對策。此外，在水資源設施之開發與推動工作，在地民眾及公民團體之意見與參與，更是計畫成敗之關鍵，如何增進各種權益利害關係人參與協商與溝通之意願，讓各方增加對話與理解彼此的目標與想法，進而凝聚共識，是重要的過程。為研議民眾或相關公民團體能透過多元管道，就其關切議題事先溝通，化解民眾疑慮，俾尋求共識爭取認同，爰辦理本計畫。

To cope with the impact of global climate change on water supply system, complying with oversea tendency, one of the feasible plans is to develop seawater desalination technology to diversify the development of water resources which will not be affected by climate condition. Tainan Desalination Plant is located at Cingkunshen of Jiangjun District, with area of 12 ha. The development scale is 200,000 m3 per day, adopting two-stage development (water production rate per day is 100,000 m3). In terms of water supply object and type of water supply, it is estimated that water supply to newly built distribution reservoir (incorporate into public water supply) in pump station and Tainan Science-based Industrial Park in 2-stage approach is more appropriate. The building cost of desalination plant is still higher than water price. Thus, it is advised to handle the construction and operation of desalination plant according to Government Procurement Law, and the water price is subsidized by government (same as general water price). Based on the principle of “Beneficiary pays, limited beneficiary gets paid”, Tainan desalination plant might cause some impact to neighboring citizens, and related feedback and reimbursement mechanism will serve as reference to draw up feasible plan. From the assessment of development of desalination plant on land, land is marginally affected. In relative terms, it might cause affect to fishermen’s lives. On the basis of fishery compensation criteria, the total fishery compensation amount is about 46,000,000 NTD. In term of integration with green energy, referring to overseas and domestic case, it is advised to adopt green energy indirectly to have more stability. For example, generate electricity with neighboring solar program (use after connect to electricity grid) or subscribe to renewable energy certificate to reduce the emission of greenhouse gas, these can drive the development in renewable energy industry. In current stage, the main cost of seawater desalination is the energy use. Referring to international cases, the flexibility of operation and efficiency of high-pressure pumper can be increased by adding converter plant. The adoption of pressure center design can be feasible plan to avoid peak flexible operation. The project has visited 10 community group or stakeholder visits and 49 opinion leaders or public opinion, and collected 108 opinions and responded appropriately. It also invited opinion leaders and public representatives to operating desalination plants in Penghu. After the visit, it has alleviated public concerns and improved the overall perception. The follow-up promotion strategy plan is mainly to strengthen friendly measures in neighboring townships, including strengthening communication and cooperation with fishermen groups, environmental protection around the plant area, overall cross-domain value-added and social and economic feedback. Other relevant important strategies include the use of tendering strategy to achieve energy-saving operation and provide a stable quality and excellent water supply, electricity demand combined with adjacent green power for overall planning, job preparation in response to the requirements of relevant laws and regulations, etc.
