Systems that were traditionally used to collect municipal wastewater in gravity sewers and convey it to a central primary or secondary treatment plant, before discharge on receiving surface waters. Conventional sewer systems are highly advanced networks of underground pipelines that transport greywater, blackwater, and in most cases, stormwater from homes to treatment facilities, utilizing gravitational forces (including pumps). As pumps are used in an increasing manner, different landscapes are being depended upon such as urban areas, hills, or flat regions.
