Sanitary Engineery

Sanitary engineering is the application of scientific or mathematical principles with to the field of sanitation, especially in regards to its effect on public health.
The term sanitary engineering is sometimes viewed as an obsolete term for environmental engineering. It is, however, more limited in its scope and is not concerned with environmental factors that do not have an immediate and clearly understood effect on public health. Areas outside the purview of sanitary engineering include traffic management, concerns about noise pollution or light pollution, aesthetic concerns such as landscaping, traffic management, and environmental conservation as it pertains to plants and animals.
Although sometimes considered synonymous with sanitary science, the phrase sanitary engineering refers specifically to an applied science in which engineering principles are utilized rather than just studied or improved.Skills within this field are usually employed for the primary goal of disease prevention within human beings by assuring a supply of healthy drinking water removing garbage from inhabited areas, and so on.
Compared to (for example) electrical engineering or mechanical engineering which are concerned primarily with closed systems, sanitary engineering is a very interdisciplinary field which may involve such elements as hydraulics, constructive modelling, information technology, project design, microbiology, pathology and the many divisions within environmental science and environmental technology. In some cases, considerations that fall within the field of social sciences must be factored in as well.
