At the POTW, harmful pollutants in domestic sewage, called conventional pollutants, are removed from the sewage and then the treated effluent is discharged into a surface water body. [38] The removed solids constitute sewage sludge, which typically receive further treatment prior to final disposal on land. (See Sewage sludge treatment.) POTWs ...
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 ...
Sewage (or domestic wastewater) consists of wastewater discharged from residences and from commercial, institutional and public facilities that exist in the locality. [2]: 10 Sewage is a mixture of water (from the community's water supply), human excreta (feces and urine), used water from bathrooms, food preparation wastes, laundry wastewater, and other waste products of normal living.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

Power failure, human error, or mechanical failure may cause similar discharge of untreated or partially treated sewage from a sewage treatment plant; but this is typically regarded as a sewage treatment plant malfunction rather than a sanitary sewer overflow. Sewage treatment plants may be designed to capture overflow from malfunctioning units ...
The global 'resistome' based on sewage-based monitoring [45] Gene-sharing network between bacterial genera [45] In 2022, genomic epidemiologists reported results from a global survey of antimicrobial resistance (AMR) via genomic wastewater-based epidemiology, finding large regional variations, providing maps, and suggesting resistance genes are ...
Water pollution, environmental health, public health, sewage sludge disposal issues A shit flow diagram (also called excreta flow diagram or SFD ) is a high level technical drawing used to display how excreta moves through a location, and functions as a tool to identify where improvements are needed.

Scholars also called attention to the importance of possible UN recognition of human rights to water and sanitation at the end of the twentieth century. Two early efforts to define the human right to water came from law professor Stephen McCaffrey of the University of the Pacific in 1992 [30] and Dr. Peter Gleick in 1999. [31]
