- Abstract:
[Extract from Chapter 1] The problem of this dissertation arises from the need of reliable unit cost estimates for construction of plants of major treatment categories. Present cost estimating data, though numerous, vary widely in format from author to author. Much of this data is reported without sufficient and representative cost information. Many authors did not take into account regional differences. Very few considered unit construction cost in terms of population equivalency [PE]. Most authors estimated unit construction costs in terms of population or flow. An intensive search of past and present literature failed to find a single article or paper which considered all the significant factors or variables with enough data to develop a reasonable mathematical model for estimating the cost of municipal sewage treatment plants. The terms "enough” and “reasonable" as used herein are meant in a practical and statistical sense. Reliable input data for use in the models is needed to make them workable or to get a better output. The authenticity of any cost estimation data is dependent upon the number of projects involved in establishing criteria, the inclusiveness of the types of projects, and local conditions under which the projects have been constructed. A few mathematical models for maximizing net benefit in the development of a water resources region have been proposed. A reliable estimate of the cost of waste treatment is one of the variables which is needed to make a mathematical model operable. Objective: The purpose of this study is to provide estimates of the cost of treating municipal and industrial wastes. The study will use statistical tools to establish a model for estimating the cost of municipal waste treatment plants. In the case of industrial wastes many statistical procedures could not be followed because of the lack of data on various types of industrial wastes. By application of the data obtained as a result of the mail survey a mathematical model will be developed to provide means for estimating the construction cost of waste treatment as a function of several variables such as, population equivalency, degree of treatment, types of processes, and flow. The model is to be simple and future independent variables reasonably easy to observe so that it can be readily applied to any region, for any major process, and at any scale, considered in the study.
