Description
Summary:The paper is concerned with the establishment of a mathematical model for estimating waste treatment plant construction costs in the United States. A mail survey over the 48 adjacent states was conducted. The categories of plants included were activated sludge, high-rate and standard-rate trickling filters, stabilization pond, and primary treatment. Industrial waste treatment plants were not surveyed. Replies from 563 waste treatment systems were statistically analyzed. Equations were developed to predict unit costs for construction in terms of dollars per design population equivalency (PE) and dollars per mgd (design flow). The Eng. News-Rec. Construction Cost Index and the Federal Water Pollution Control Administration Sewage Treatment Plant Construction Cost Index were used to adjust cost data from different areas to a common base. Two methods were used to develop the equations, analyzing the data of each type of plant separately, and combining the data and using dummy variable to quantify the type of treatment plant.
