Undeniably, a sewage treatment plant does much more than a septic tank. They are strong, durable and require far less maintenance. While a wastewater treatment system is more costly to purchase outright, it can save you a lot of time and money in the long run with less need for emptying and a decreased risk of blockage.

The winner: home sewage treatment plants

A sewage treatment plant has the upper hand over septic tanks because they actively treat the incoming wastewater by adding oxygen, accelerating the natural biological process. The biggest downside to a home sewage treatment plant is the reliance on a power source, if a power outage occurs the mechanical process within the treatment plant may fail, causing the bacteria to die off. In this instance, the tank will need to be emptied and reset with new bacteria. Home sewage treatment plants treat the water in an environmentally friendly way through making use of the naturally polluted or degraded water.

A home sewage treatment plant is a modern device that treats all wastewater that is generated through domestic dwelling. Though they have a higher upfront cost, they can be incredibly cost effective and environmentally friendly in the long run.

A home sewage treatment plant is a smaller version of commercial treatment plants used in metropolitan areas. The system consists of 3 compartments used to clear sewage from all physical waste, harmful bacteria and pollution. On the other hand, septic tanks simply separate the gunk and waste from the water, turning it into a sludge.

Sewage treatment plants and septic tanks both receive and treat the sewage and wastewater from your household dwelling. While the two types of sewage management systems perform the same task, there are key differences that impact their overall output and efficiency. Firstly, home sewage treatment plants have mechanical components, requiring a permanent electrical supply to operate.

Septic tanks are a traditional style of waste management, with a low upfront cost they are well suited to smaller households or properties. Strictly speaking, a septic tank is not a sewage treatment plant, but it can be used as part of a sewage treatment plant or system. Septic tanks require emptying at least once a year, whereas sewage treatment plants have emptying intervals between 30 to 60 months.


Septic tanks work by separating wastewater into solids, clean liquids and floating contaminates. When wastewater passes through the septic tanks, heavier solids sink to the bottom and undergo bacterial digestions. However septic tank effluent requires further processing once it has left the tank. Low quality septic tank effluent can lead to pollution of groundwater and streams.

Key differences between a septic tank and a home sewage treatment plant

Sewage management is essential for every household. While many homeowners rely on local governments to manage their sewage, in remote areas, relying on an existing sewage system is not always possible. When homeowners are making the decision between installing a septic tank or sewage treatment plant, they need to understand the key differences between the two sewage management systems.


In simple terms, septic tanks and home sewage treatment plants do the same thing. However, there is a clear difference in efficiency and effectiveness in treating wastewater. Let’s go through the pros and cons of septic tanks and sewage treatment plants to help you make the best decision for your household.
