Ebook Sewerage

During the twenty years since the first edition of "Sewerage" was published effort has been made to keep it up-to-date by revising it from time to time, six such revisions having been made. Developments in the science and art, however, seem to call for a more general revision of the entire arrangement of the work and a change in typography and illustration to bring it more into keeping with recent practice. The author has consequently rewritten the entire book, making very considerable changes in the portions dealing with sewerage systems, but only minor ones in those treating of sewage disposal, which was rewritten about two years ago.

Among the more important changes are the devoting of more space to the calculating of the sizes of sewers, especially storm sewers, and to pumping sewage; the condensing of Part II - Construction, and Part III - Maintenance, each to one chapter; and the use of many more illustrations, only a few of those in the previous editions being used.

The aim throughout has been to cover thoroughly the fundamental principles and approved practices of both sewerage and sewage treatment, giving the latest developments in each but using caution in crediting enthusiastic claims, even of experts, until fully substantiated by practical experience.
