Conventional Gravity Sewer

Conventional gravity sewers are large networks of underground pipes that convey blackwater, greywater and, in many cases, stormwater from individual households to a (Semi-) Centralized Treatment facility, using gravity (and pumps when necessary). When blackwater and stormwater are collected in the same pipe, conventional sewers are also called combined sewers.
