Sewage treatment (or domestic wastewater treatment, municipal wastewater treatment) is a type of wastewater treatment which aims to remove contaminants from sewage to produce an effluent that is suitable to discharge to the surrounding environment or an intended reuse application, thereby preventing water pollution from raw sewage discharges.

Sanitation refers to public health conditions related to clean drinking water and treatment and disposal of human excreta and sewage. [ 1] Preventing human contact with feces is part of sanitation, as is hand washing with soap. Sanitation systems aim to protect human health by providing a clean environment that will stop the transmission of ...
A sanitary sewer is an underground pipe or tunnel system for transporting sewage from houses and commercial buildings (but not stormwater) to a sewage treatment plant or disposal. Sanitary sewers are a type of gravity sewer and are part of an overall system called a "sewage system" or sewerage. Sanitary sewers serving industrial areas may also ...
Sanitary manhole. A sanitary manhole ( sewer manhole, [1] sanitary sewer manhole [2] or sewer maintenance hole [3]) is a manhole that is used as an access point for maintenance and inspection of an underground sanitary sewer system. Sanitary manholes are sometimes used as vents to prevent the buildup of pressurized sewage gas. [4]
Aerobic treatment system. An aerobic treatment system ( ATS ), often called an aerobic septic system, is a small scale sewage treatment system similar to a septic tank system, but which uses an aerobic process for digestion rather than just the anaerobic process used in septic systems. These systems are commonly found in rural areas where ...
Climate change is raising the risk, rate and cost of sewage failures. Floods are becoming more common, leading to backups that frequently overwhelm wastewater treatment systems.
Wastewater treatment. Wastewater treatment is a process which removes and eliminates contaminants from wastewater. It thus converts it into an effluent that can be returned to the water cycle. Once back in the water cycle, the effluent creates an acceptable impact on the environment. It is also possible to reuse it.
In most cases these will be lower compared with other wastewater treatment alternatives. [20] [4] Depending on the specific situation of the area, construction costs can increase and level up with other technologies. [citation needed] Waste stabilization ponds are one of the cheapest wastewater treatment processes in terms of operation and ...
