Although it is 2.6 times greater than worlds average, water resources are less effey used because of steep slope. In additional, the greenhouse effect is affecctivelting global climate change resulting in rising of sea level and the geographical environment is vulnerable to typhoons, the lower region especially the coastal area is easily inundated. In order to improve the drainage of lower region, the government subsidizes the funds every year to improve or construct drainages, gates, pumping stations, detention pools and wetlands. However, the funds are limited and the flood problems can’t be solved in one step. It is necessary to analyze the feasibility of all strategies to achieve the highest value in lowest cost. It ought to be the key that government evaluates the methods of flooding control. Upgrading the prevention of inundation problems in village is especially the most important thing. Generally speaking, the more useful and obvious strategy of preventing village is village-surround embankment with the setting of pumping stations。This research compared the costs of different type facilities in the pumping station and concluded the most favorable equipment-configuration. The Dong-Shih pumping station was the studied sample. Through assessing the possible economic benefits from different combination of gates and pumps, the research made the conclusions and suggestions to the design and plan of a pumping station and be a reference for public and private departments.
