1) Vacuum sewerage systems is an alternative method of waste water collection that uses differential air pressure rather than gravity.
2) The system has three main components - collection chambers at each house, vacuum lines that transport sewage in a saw-tooth profile, and a vacuum station that maintains the negative pressure and pumps the sewage.
3) Vacuum sewerage systems provide advantages over traditional systems such as lower costs, flexibility in pipe layout, and ability to operate in difficult terrain. They are particularly suitable for rural and low-density areas.
