Sewer Classifications and their Advantages and Disadvantages
Both commercial and residential areas have their unique sewer system. There are various classifications of sewers types and each of these has its own features, benefits, and certain drawbacks. Using the right sewer system for your property will not only optimise waste disposal but also save you from debilitated sewer pipes and a flawed sewage outlet. Below are some sewer classifications as well as a short summary of their advantages and disadvantages.
Combined Sewer Types
As what its name implies, this sewer type is a combination of drain pipes that are from industrial waste, sewage waste, and stormwater. Basically all the waste from these three major pipelines are centralised into one pipe which then leads to the nearest treatment facility near the area. It certainly has a lot of advantages, and one of which is the convenience for the property owner since little involvement is required, and both stormwater and wastewater are processed at the same time. Also, it’s completely a sanitary sewer type system and you won’t smell any sewage odours or have your house swarmed by sewer pests. The costs for running and maintaining the sewer system are also not too expensive.
Combined sewer types have a bit of drawbacks that hinder it from being a perfect system. The primary shortcomings are the high initial costs of installing the sewage system as well as the complications in setting it up in high-volume areas. Maintaining combined sewers many not be too expensive but you’ll be unable to fix anything on your own since professional engineers and operators are needed for such work since it’s really more complex than people imagine it to be.
Separate Sewer Types
Contrary to combined sewer system, the wastewater and stormwater drain pipes in separate sewers are independent and don’t share the same treatment outlet as its name would suggest. This sewer type is more suitable for locations that experience heavy and frequent rainfall throughout the year. The dedicated stormwater pipe will be able to effectively discharge the excess floodwater. This rainwater can actually be used for agricultural and landscaping purposes. Combined sewer types on the other hand may have difficulty in dealing with constant stormwater since the pipe system will be stressed. It has to process both the sewage waste and the excessive stormwater. Separate sewers have little to no chance of having a sewer overflow, and have less risk of having sewer leaks and sewer pest outbreak. The operating cost is also not too expenstify;”>It shares the same disadvantages with combined sewer systems like the requirement of skilled workers for maintaining the sewer and the difficulty in installing in areas that are densely populated. Separate sewer systems are actually more expensive than the combined version in terms of initial operating and installation cost. There will also come a time when obstructions and equipment malfunction will occur and you won’t be able to fix it on your own or do major precautionary repairs since sewer system experts are needed.
