Excerpt from Practical Treatise on Water-Supply Engineering: Relating to the Hydrology, Hydrodynamics, and Practical Construction of Water-Works, in North America, With Numerous Tables and Illustrations There is at present no sanitary subject of more general interest, or attracting more general attention, than that relating to the abundance and wholesomeness of domestic water supplies. Each citizen of a densely populated municipality must of necessity be personally interested in either its physiological or its financial bearing, or in both. Each closely settled town and city must give the subject earnest consideration early in its existence. At the close of the year 1875, fifty of the chief cities of the American Union had provided themselves with public water supplies at an aggregate cost of not less than ninety-five million dollars, and two hundred and fifty lesser cities and towns were also provided with liberal public water supplies at an aggregate cost of not less than fifty-five million dollars. The amount of capital annually invested in newly inaugurated water-works is already a large sum, and is increasing, yet the entire American literature relating to water-supply engineering exists, as yet, almost wholly in reports upon individual works, usually in pamphlet form, and accessible each to but comparatively few of those especially interested in the subject.
