Abstract

Since the per capita loading research work of the 1900-1927 era, little has been done to continue this work or re-evaluate the wastewater design parameters that had been developed. These parameters include per capita loadings for BOD, COD, and solids, as well as per capita wastewater flow data, flow variation and wastewater temperatures. For some forty to fifty years, engineers have been content to use these loading values with little concern for their applicability. The reason for questioning the current applicability comes about because of changes in modes and standards of living, and technological advances, in addition to the innate problems of the original work. This research work has been designed so as to follow as closely as possible the basic methods of earlier researchers. However, numerous refinements of method and equipment have been utilized in an attempt to improve the reliability and quality of the data. Sampling method and location have been modified and automated, a strictly controlled research area has been used, and an accurate and thorough census has been taken. The coupled effect of the old and the new has therefore provided for continuity of thought as well as a current re-evaluation of the loading parameters.
