Book Description
Excerpt from Sewerage and Sewage Disposal a d104book 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 superficial 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 is 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 conditions or those involved in specific methods of treatment. Yet some college classes in sewerage engineering receive no instruction 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. This book can be used in two ways. The text can be read and mastered within the time allotted to the subject even when the course is very short.
