| Abstract | The purpose o f this study were to collect., categorize , and analyze construction bid data and operation / maintenance cost data for waste water treatment plants nation wide with goal of providing a reference. for estimating future facility costs. To accomplish this, construction bid information was obtained from association . All facilities sampled are industrial wastewater treatment plant funded after 1973 . The 35 treatment plants construction projects were sampled , and only 25 of them were available of sufficient data for analyzing . During data analysis, it was assumed the cost of treatment plant could be viewed from three perspectives : the cost of entire plants, the sum of the cost of the individual construction unit process and the s um o f the cost of individual construction components such as steel , concrete,. .. etc. Therefore, construction cost data were categorized according to three levels of detail. Using linear regression analysist technique cost curves developed relating item cost to plant design flow for each of data . Method of estimating wastewater treatment plant based on first quarter of 1989 new Taiwan dollars using construction cost indices. In practical , several cases in sufficient data were available to develop valid relation ships for specific unit processes or construction components. In other cases a equated at a were available to define cost relations hips for individual types of plants. As more construction cost history becomes avai1able , it is expected that the current data base will be expanded and up date regularly providing a more complete series of cost estimating relation ship . Due to economical fluctuation , cost functions, actualized by using the cost indices for construction , presented in this study , preferred normally comparison used to prediction used . The fitful range scale use d in this study differed from 1 25 0 m3 /d to 30000 m3 / d , that means flowrate out of this range will be some what more un certain . 'Main treatment unit processes of wastewater treatment like pumping station , screening, preliminary treatment , equalization , sedimentation , clarifier , drylined ,... etc were considered and were compared with literature, especially with EPA functions of U. S. A. Differences were found And causes are discussed . This study supplies information for the foreign investors as well as for domestic manufacturers to estimate costs for wastewater treatment in Taiwan . |
