Outhouses in Brisbane, Australia, around 1950. A significant development was the construction of a network of sewers to collect wastewater. In some cities, including Rome, Istanbul (Constantinople) and Fustat, networked ancient sewer systems continue to function today as collection systems for those cities' modernized sewer systems. Instead 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 .
An example of a wastewater treatment system. Sanitary engineering, also known as public health engineering or wastewater engineering, is the application of engineering methods to improve sanitation of human communities, primarily by providing the removal and disposal of human waste, and in addition to the supply of safe potable water.
Access to the sewer systems, as well as having plumbing and other water-based luxuries, was seen as a sign of status in Roman society. Access was only granted to those who paid for it. Additionally, archaeological sites and ancient texts show evidence of the first European waste management labor force. [ 6 ]
The Washington Suburban Sanitary Commission (WSSC) was established in Maryland in 1918 and operated sewer systems in portions of Montgomery and Prince George's Counties. The commission began to install sewer connections from its service area to the Blue Plains plant in the late 1930s and 1940s.
Map of London sewer network, late 19th century. Sewerage (or sewage system) is the infrastructure that conveys sewage or surface runoff (stormwater, meltwater, rainwater) using sewers.

The mill store was greatly expanded the same year, incorporating the old frame structure and adding a gymnasium, theater, two community rooms, and other amenities. Beginning in 1922, the village houses were wired for electricity, and sidewalks and a sanitary sewer system were added. Further houses were built, bringing the total to 279 by 1925.
As more iron moves into solution, the result is a loss of pipe structure over time potentially affecting pipe integrity. In storm and sanitary sewer systems, the creation of acidic gases (such as hydrogen sulfide) by microbial action can further corrode internal pipe walls but is most pronounced on the inside ‘ceiling’ of the pipe.
