It is the primary duty of our system to create a passageway for sewages and wastewater and convey them to their designated destinations away from our homes. We all know that they are oftentimes naturally composed of manholes for inspectors and workers to easily access the system, drains from various households, screening chambers and we might have seen these things while walking on pavements. But the various types and sorts of sewer systems are not very known to many homeowners. Yes, indeed there are many kinds of sewer system used in many residences and industries and each of them differs from each other. Here are the five major sorts of sewer system.

 

  • Storm sewer or drain system

Storm sewer system is specifically created to drain excess amount of rainwater artificial structures which includes parking lots, pavements and streets. This may vary in designs and can have different forms or construction from residential to larger areas.

  • Combined sewer system

This sewer system is specifically created to convey water run-off. This is oftentimes composed of various pipes intended to gather these run-offs. Surface runoff is the circulation of water that happens when excess rainwater flows to the earth’s surface. This often happens when the soil is soaked off to its full capacity which is the primary reason for soil erosion occurrences.

When this sewer system was first introduced to the public, it has been adored because of how it helped the society. But when the heavy rain arrived, its advantage has been revealed. This water system tends to overflow when too much storm water has been gathered and has exceeded the sewage plant capacity which can greatly cause contamination and earnest water pollution to many water course where it is supposed to be discharged. This causes many residence areas to not opt for this system because of its disadvantage.

  • Effluent sewer system

This type of sewer system is oftentimes called STED (Septic Tank Effluent Drainage) or SFS (Solid-Free Sewer). This sewer system is composed of a septic tank that gathers the wastes materials from industrial and residential areas. The gathered wastes will then be dispatched or conveyed to their designated destinations, either the distributed treatment or the sewage treatment plants.

It is termed solid-free because the solid is taken out by the tank. The plant being utilised in this system can be smaller compared to the usual tank. Because of that, because of the huge reduction of solid particles, another alternative used when conveying these wastes could be a pumping system.

  • Sanitary sewer or foul sewer

From the name it suggests, this sewer system is expected to convey and transport sewages and sewages from residential and industrial buildings. After gathering these wastes, they will either be disposed or treated.

When the sewages are to be treated, it will undergo a certain process that would take out the contaminants from the sewage. This involves the chemical, physical and biological process. The sewage would undergo these stages for it to be completely treated. After treating them, the water will be either discharged into a water course or used in irrigation systems.

  • Simplified sewerage

Simplified sewerage gathers wastewater from households and industries and these waste waters can be either black or grey. Grey water refers to those without the mixture of human waste. They can be from bathtubs, showers, sinks, and the water from washing machines. They are safer and easier to handle compared to black water which contains human wastes, specifically the wastewater coming from your toilets.
