Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.
The main part of such a system is made up of large pipes (i.e. the sewers, or "sanitary sewers") that convey the sewage from the point of production to the point of treatment or discharge. Sewers under construction in Ystad, Sweden. Types of sanitary sewer systems that all usually are gravity sewers include: Combined sewer; Simplified sewerage ...
