西部小城镇供水厂站制水成本分析

在参考现有的国内供水厂站费用指标及国内外费用指标费用模型的基础上,结合重庆市城镇的人工和材料价格,得出重庆市小城镇给水取水工程和净水工程的造价指标值和造价公式,再根据西部其他地区的设备运杂费费率及调整系数即得到适用于西部小城镇的供水厂站投资估算指标.最后,在分析成本构成的基础上,结合投资指标费用模型,对西部小城镇供水厂站的制水成本进行了分析,得到了西部小城镇供水厂站的单位制水成本.

Cost analysis of water-supply plants in small towns in western China

We derived the cost index value and cost formula of water-supply and water purification in small towns in Chongqing,P.R.China,based on the economic index of domestic water-supply plants,the cost model of domestic and overseas economic indices,and local labor and materials prices.Investment estimation indices for water supply plants in western small towns subsequently were obtained according to the equipment transportation rate and adjustment coefficients in other areas of western China.We analyzed the cost of producing water in water-supply plants in small western towns based on the cost structure analysis and the cost model of investment index,and subsequently derived the unit cost for producing water.
