Water supply projects, under normal circumstances, may be designed for a design period of 30 years. Industrial Water Demand 50 lpcd — Ordinary per capita consumption for industrial needs of a city is generally taken as 50 lpcd. Porosity of the soil: It is defined as maximum amount of water that can be stored in the rock. A rock which is porous, may or may not be permeable. Permeability is measured in terms of coefficient of permeability. Types of parasitic Organisms Infective to man Found in Water.

The development of sanitary engineering has paralleled and contributed to the growth of cities. Without an adequate supply of safe water, the great city could not exist, and life in it would be both unpleasant and dangerous unless human and other wastes were promptly removed. The concentration of population in relatively small areas has made the task of the sanitary engineer more complex Groundwater supplies are frequently inadequate to the huge demand and surface waters, polluted by the cities, towns, and villages on watersheds, must be treated more and more elaborately as the population density increases. Industry also demands more and better water from all available sources. The rivers receive ever — increasing amounts of sewage and industrial wastes, thus requiring more attention to sewage treatment, stream pollution, and the complicated phenomena of self — purification. The design, construction, and operation of water and sewage works are treated in this book, but the field of sanitary engineering extends beyond these limits The public looks to the sanitary engineer for assistance in such matters as the control of malaria by mosquito control, the eradication of other dangerous insects, rodent control, collection and disposal of municipal refuse, industrial hygiene, and sanitation of housing and swimming pools. The activities just given, which are likely to be controlled by local or state health departments, are sometimes known as public health or environmental engineering, terms which, while descriptive, are not accepted by all engineers.

Since the dawn of civilization, humans have transformed the environment to accommodate and satisfy their needs. Advances in agriculture, mining, manufacturing, transportation, and energy production, for example, have dramatically improved standards of living over the centuries. Human impacts on the environment accelerated with the advent of the Industrial Age and the subsequent rapid growth of the human population, creating significant areas of friction between human societies and the environment.
