Sewers: Sewers are the pipes that carry the wastewaters from various sources to water reclamation centers where they are treated.The three main components of a sewer system are – sewers, pumping stations and water reclamation centers.
What are the Components of a Sewer System? Outfall Sewer: This receives the total discharge coming out from all sewer systems and moves it forward for final disposal.Main Sewer: Main sewer receives the discharge from more than one sub-main sewers.Sub-Main Sewers: These sewers carry sewages from more than one lateral sewers.Lateral Sewers: These sewers carry sanitary sewages from more than one house sewer.House Sewer: This the sewer system which is most commonly found in domestic houses where the plumbing system in a house is connected to the municipal sewers to carry out sanitary sewage.Combined Sewers: These sewers carry sanitary sewage (domestic and industrial wastewater) and storm sewage.Storm Sewers: These sewers carry storm sewage including street wash and surface runoff.Sanitary Sewers: As the name suggests, these sewers carry sanitary sewage i.e., wastewater from municipal sources – domestic and industrial wastewater.There are several types of sewers that are found today. This type is also prevalent in cases where streets are very narrow for laying out separate sewers.Ĭheck out this article on Sewage and its types here. Combined sewer systems are preferred in cases where sewage wastewater does not require any treatment or when each one requires treatment. Combined Sewer System: In this system, there are no separate sewers but one sewer which carries storm water, industrial water, and domestic water.This is preferable in cases where there is an immediate requirement to collect domestic and industrial wastewater and not storm water and also when storm water does not require any treatment, but the sanitary sewage does. The storm water is separately drained out. Separate Sewer System: In this system, there are two separate sewers – one for domestic and industrial wastewater and the other for stormwater.There are generally two types of sewer systems that functions today in most countries – What are the Different Types of Sewer Systems?
