The Cost of Water Treatment by Coagulation, Sedimentation, and Rapid Sand Filtration
This paper presents the results of comparative cost engineering audits made on 30 water treatment plants in 1965. The term “cost engineering audit” refers to a detailed investigation and analysis of the physical characteristics, the operating data, and the costs of a plant or other operating installation, and the presentation of these in a standardized manner so that internal and external comparisons can be made. The objectives of the study were to: determine which elements, differentiable from the available plant data, make up the cost of water treatment; determine the relative magnitude of the contribution of each differentiable element; determine the unit consumptions or unit utilizations and the pertinent design factors and operating ratios for the plants studied; determine the unit investment and unit prices paid for materials and services; obtain the unit costs of selected cost elements, or, their contribution to the total cost of treatment; determine the distributions of these operating ratios, design factors unit prices, unit consumptions, and unit costs among all plants in the study; determine the effect of plant size on certain of these ratios such as unit prices and unit investment; determine the effect of climatic, geographic, or administrative factors on certain of these ratios; and, determine the effect that water quality parameters have on the components of water treatment costs on the total cost of water treatment and on the various operating ratios.
