Excerpt from Sewerage and Land-Drainage
Attention will be called to the fact that drainage-works. Past and present, are, and have always been, the outgrowth of tradition, as modified from time to time by a better knowledge Of what it is necessary or desirable to accomplish. The earliest subterranean works, as far as they are still retained in use, were Obviously intended to prevent an interference with the convenient use Of' the surface by open water-courses. Later, as inconvenience was felt from the accumulation Of surface water falling on paved and other impervious surfaces, drains were extended to relieve the diffity thence resulting. When the introduction of a public water-supply overtaxed existing facilities for the storage or removal Of household wastes. First the superabundant liquid and later the whole foul flow was delivered into the Old drains. Annoyance arising from the discharge Of organic wastes into the rough channels originally intended for surface-water, means were deed for improving the form and construction Of the conduit so as to reduce the amount Of deposit. Still more recently a com prehension Of the sanitary importance of a complete immediate removal of foul wastes led to the construction Of sewers especially for this purpose. In many cases storm-water, except that falling on back roofs and yards, was excluded. The latest step, and, as I think, a very important one, and which - in practice - originated with me. Secured the exclusion even Of this relatively small proportion of storm-water and the substitution of artificial means for keeping the sewers clean by frequent and regular flushing.

Paperback. Etat : New. Print on Demand. This book delves into the crucial subject of sanitation and its impact on public health, a topic that has been of paramount importance since the dawn of civilization. The author, a leading engineer of his time, skillfully navigates the complex history of sanitation practices, from the rudimentary methods of early communities to the more sophisticated approaches emerging in the 19th century. The book's central argument is that sewer systems, when properly designed and implemented, play a vital role in safeguarding public health by ensuring the swift and complete removal of waste materials that could otherwise breed disease. The author examines the key role that bacteria play in the decomposition of organic matter, revealing insights into the delicate balance between the bacteria that contribute to soil fertility and those that threaten human health. The book emphasizes the importance of immediate waste removal as a primary means of controlling the spread of infectious diseases like typhoid fever and cholera, and explores the merits of water carriage as a means of transportation for waste materials. This book explores the complexities of public sanitation and offers a blueprint for improving public health through effective waste management. It remains a valuable resource for understanding the scientific and historical context of sanitation practices and their impact on human well-being.
