Sewer vs Septic Drainage System Comparison


Drainage systems are designed to dispose of wastewater whenever a toilet is flushed, the washing machine is working, or when someone washes their hands. No matter if we are talking about residential or commercial houses or building, drainage is important. The choice narrows down to sewer and septic drainage system, so which one is better?

At the moment, sewer systems are a standard because they are provided and maintained by the government. However, more and more households are starting to use septic systems, as they are affordable, they protect the environment, and they give owners better control of their drainage system.


Even though most people think that septic systems cost more due to the emergency septic tank service, installation, and maintenance, this isn’t quite true. First of all, sewer systems come with similar costs, as homeowners can often be forced to pay large fees for repairs and installation.

A lot of communities also have to pay Sewer Betterment fees and get higher costs as the pumping stations expand. On the other hand, septic system costs mainly revolve around pumping, which needs to be done every 3 to 5 years and the costs can go up to $300.

Effects on the environment

As more and more people are starting to care about the environment, there are more households that are using septic tanks because they are eco-friendly. Sewer systems require chemicals and energy to pump the water and in case of large water surges, treatment plants have difficulties with cleaning the water.

When it comes to septic systems, these problems are not present as the water is pumped without spending any chemicals or energy. All the used water goes back into the aquifer that can never be overflowed if it is maintained properly. At the same time, the system can’t be overworked, as it is designed for the needs of a single household.

Most notable differences

A septic system is very appealing because it can be set up anywhere where there is healthy soil. For example, if someone buys a house in a remote area that is far away from urban neighborhoods, it can be difficult and costly to install a sewer system, while septic tanks can be implemented quickly and at an affordable price.

This is why septic systems are a worthwhile alternative. On the other hand, once installed, there is no need to worry about infrastructure, renovation, repairs, or pumping stations, as you’ll be completely independent.


Septic systems are a worthy alternative that isn’t expensive and is, in fact, often cheaper. The important thing is to maintain your tank properly, use dosing pots and it will serve you well for a long time.
