Collection Systems

The collection systems form a part of sanitary engineering, which is a sub-branch of civil engineering. It is also known as public health engineering and wastewater engineering. It is a methodology followed to remove and properly dispose of human waste, along with creating systems to provide safe and clean usable water. These measures ensure a hygienic and disease-free community. Sanitary engineering, apart from building sewer disposal units, is also involved in plumbing, fire protection, hydraulics, life safety, environmental protection, information technology, microbiology, pathology, and so on.
