Every homeowner never wishes to encounter drainage issues, but the reality is that plumbing issues are often always inevitable. Even new homes are not exactly free from drain issues. At some point, you might experience a slow-moving drain or a completely blocked sewer line. Even if it’s a minor issue, knowing what to do can save you some trouble.
It’s essential to understand how your home’s drain system works, so you know exactly how to address issues arising in the drainage. In this post, we’ll dive deeper into understanding the sewer drain system as it applies to residential and commercial buildings and how to care for and prevent drain issues in your home drainage system.
What is Sewer Drainage?
To understand sewer drainage, let’s first explain what sewer means. Sewer is
the wastewater generated by a community of people. Wastewater or Sewage is typically discharged from the plumbing of residences, commercial, institutional, and public facilities in your town or city. Sewage can be greywater or blackwater.
Sewer system or sewer drainage is a kind of drainage system drain is a network of underground pipes that carry sewage, wastewater, and surface water to a sewer. The sewage is then carried to an onsite sewage facility or a sewage or wastewater treatment facility. During sewage treatment, the wastewater is treated to remove the sewage contaminants.
This process aims to produce an effluent that can be discharged into the surrounding environment or reused in other applications. Decontamination or sewage treatment before discharge or reuse helps prevent water pollution from raw sewage discharges. Note that the generation of wastewater is proportional to the water use rate in buildings within a locality.
How Sewer Systems Work
Understanding how sewage systems work allows you to know how wastewater is generated and how it ends up in wastewater treatment plants.
The sewage system starts from residences and commercial facilities in an area. As water is used in homes — in kitchens and bathrooms — and in commercial and industrial buildings, wastewater is generated, and it flows through drain pipes, from sinks, toilets, and bathtubs, and runs underground into the sewer system leading from the buildings to the city sewer system.
The flow of sewer from buildings to the local sewer mostly depends on gravitational pull. An essential aspect of wastewater treatment is the removal of solids from the wastewater so that the sewage will separate into sludge and water. Secondly, oxygen is added to the tank to promote the growth of microorganisms which, in turn, consumes the leftover waste in the wastewater and then settles at the bottom of the tank.
After this, about 90% of the waste, including solids and chemicals, has been removed from the wastewater. The leftover sludge is further processed in sludge digesters to eliminate bacteria. The sludge is dewatered in another plant, then dried and converted into fertilizers.
What Causes Sewer Problems?
Several reasons lead to sewer blockage or sewer backup in any building. The most common sewer problems are slow-moving drains, clogged drains, sewer backup, and in some sewer cases, sewer pipes may end up broken. To prevent sewer problems, one needs to know the factors or activities that lead to specific sewer problems.
Practicing good use of your home’s drain system is a great way to save yourself from having to deal with multiple sewer issues. Here’s are a few causes of sewer problems:
Broken drain pipes: when your drain pipes become broken, you can expect to experience sewer problems, and the sooner you locate the faulty pipes and repair or replace it, the earlier you can stop the issue from deteriorating.
Grease and fat: as grease from food continues to accumulate in your sewer line, it could lead to clogged drains as well. To correct this, you can run hot water down the drain. However, if there’s a massive clog of grease, it is best to get the help of a drain specialist because the grease will simply line the drain pipe, then cool and solidify again.
Debris: all sorts of waste pass through drain pipes and sewer lines. Over time, debris, food particles, and other solid waste, including foreign wastes, will accumulate and block the sewer line.
Tree roots intrusion: tree roots extend many meters under the ground, so if you live in areas with lots of trees, you want to watch out for roots growing in your drain lines. Even if you don’t have a tree planted close to your mainline sewer line, this can also happen. In severe cases, it can become a total blockage.
Sagging sewer lines: when sewer lines begin to age, it can lead to soil shifting or formation of sinkholes, thereby leaving the wastewater from the sewer line to gather in pools in the lower parts. This causes the water not to drain correctly and eventual sewer backup.
