Synopsis
Excerpt from Sewerage and Sewage Disposal a Textbook
Since the three volumes of American Sewerage Practice were published in 1914 — 1915, the authors have been urged to prepare a single-volume abridgment of them for class use in engineering schools. The authors were reluctant to do this, because of two conditions. The first is the great variation in the time devoted to sewerage engineering in different schools. This has the result that a textbook so brief as to verge on the super ficial from the viewpoint of one class may be too detailed for another. The second condition is the fact that some of those features of sewerage engineering which in practice it 18 most important to master are apparently held by those laying out college courses to deserve little attention from students. For example, a wise estimate of the quantities of sewage and storm water to be handled is the basis of design of a sewerage system, yet the methods of preparing such estimates and actual practice in their use receive relatively little attention in college courses. Furthermore, the best arrangement of the main sewers in a sewerage plan may depend largely upon the treatment, if any, that the sewage must receive before disposal and upon the place of disposal, subjects involving a knowledge of the nature of sewage and the changes which it undergoes under natural con ditions or those involved in specific methods of treatment. Yet some college classes in sewerage engineering receive no instruo tion in sewage treatment. As the requests for a textbook continued, the authors finally decided to prepare a book giving the information which they consider it desirable for the young student to acquire before taking up work in this field. In a sense, they have felt under obligations as professional engineering specialists to do their part in smoothing the way for the first steps taken by engineering students in this branch of engineering.
Présentation de l'éditeur
This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.
