Sewerage and Land-Drainage (Classic Reprint) by George Edwin Waring Jr Pdf
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 difficulty 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 devised 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. All sanitarians are agreed that, so far as the removal of foul waste is concerned, whatever the system by which it is effected it should be immediate and complete, and that this principle Of imme diate and complete removal should relate not only to the public sewer, but equally to every element of the tributary system by which waste matters are conveyed from their place of production in the house to the sewer. This calls for the consideration Of the construction Of the appliances from which, or through which, waste refuse is carried from its point of production to the public sewer or to other means of disposal - that is, all that is included under the general head Of house-drainage. As I have discussed this subject somewhat fully in a recent work, * it will be considered here less in detail.
