5 Various Types of Sewage Systems

types sewer system

Most of us probably have a notion that sewage system is made up of one type and has a sole purpose that is to carry sewage and wastewater. However, the former notion is incorrect.  There is various sewage system that can be utilised in industrial and domestic establishments with various features for different purposes.

Here are some common types of sewage system:


Combined sewers

Similar to other sewage system, this type carries and transports industrial sewage and domestic wastes.  Combined sewers are connections that are installed below ground. All connections have one single centralised pipe that connects straight to the treatment plant.

Since its purpose carried sewage and wastewater, it is created to keep a self-cleaning velocity. Each sewage has a specific velocity so that particles won’t stay within the pipe’s interior. Its velocity can be maintained through an uninterrupted downhill declivity. On the other hand, if it failed to keep, pumping utility mustn’t be installed. This should be followed to make sure that the community’s hygiene and comfort in using the system as well as getting its environmental benefits are maintained. Like any sewage, its common setback is that its installation process is complex and its cost is big-ticket.


Separate sewers

Apparently, this sewage conveys stormwater and wastewater separately. In contrast to stormwater sewers, sanitary sewers convey and gather domestic wastewater. Similar to combined sewers, its cost of labour is expensive, however, homeowners are guaranteed that it provides satisfactory service pertinent to comfort and hygiene. To stave of overflow issues separates pipes that carry both stormwater and wastewater are hooked up directly to the treatment plant.


Simplified sewers

Simplified sewers are constructed and settled down with lesser declivity and has lesser diameter compared to others. Aside from its advanced modified features, simplified sewer are likely similar to conventional sewers. Few of its modified features includes tailing off its cover and diameter, choosing comprehensible inspection chambers, sewer’s path choice and lastly, determining the slope though a concept known as tractive force.

Unlike other sewage system, its installation procedure doesn’t involve in complex techniques since the sewage can be settled on a shallower depth thus, excavation procedure is no longer necessary. Furthermore, its installation cost is us low as 50-80% cheaper than conventional sewage.


Solid sewers

This type of sewer is removed solid particles before it enters the system. In contrast to another system, solid sewer is immensely different. In the system, inspection chamber is installed to get rid of the solid particles coming from the wastewater to keep the efficiency of the system. Most of the time, solid sewers are installed in areas which are high populated with lesser are for a sewer system.


Pressurised sewers

Apparently, this system utilises pressure rather than gravity to carry wastewater. The process can be made possible through pump installation. Moreover, effluents are ground before transporting to the pump system.

Pressurised sewers are reliable yet it’s quite expensive when it comes to its installation cost that becomes a factor to homeowners why they don’t want to opt for the system.
