An advantage of sanitary sewer systems is that they avoid combined sewer overflows. Sanitary sewers are typically much smaller in diameter than combined sewers which also transport urban runoff . Backups of raw sewage can occur if excessive stormwater inflow or groundwater infiltration occurs due to leaking joints, defective pipes etc. in aging ...
A sanitary landfill is where waste is disposed of in thin layers little by little; each layer is covered and compacted with soil to prevent foul odors and wind blown litter.

Effluent sewer systems are a much less common sewage disposal method than gravity sewer systems that use gravity, as well as pumping where needed, to send raw sewage and other wastewater straight from consumers to a sewage treatment plant. There are two main types of gravity sewers, sanitary and combined. Sanitary sewers only treat the ...
Incineration is a disposal method in which solid organic wastes are subjected to combustion so as to convert them into residue and gaseous products. This method is useful for the disposal of both municipal solid waste and solid residue from wastewater treatment. This process reduces the volume of solid waste by 80 to 95 percent. [42]
Sewer systems are usually administered on the local level, usually citywide, and usually by the city itself. These systems, which may operate independently or as a subdivision of a city or other municipal agency, are typically operated as Enterprises , meaning that they produce enough revenues to fund their own activities.
