Septic Tanks & Sewage Plants - What's The Difference?

What Is A Septic Tank?
multiple chambers. Wastewater enters one end of the septic tank, before being separated into solids (sludge) and oils (scum). The separated wastewater (effluent) then leaves the septic tank via an outlet and goes into a drainage field.
through the ground to remove bacteria, before being dispersed and rejoining watercourses.

How Does A Sewage Treatment Plant Work?
way. Rather than just separating the sludge and scum from the wastewater, a sewage treatment plant uses a pump to aerate the chamber. This process encourages the growth of 'good' bacteria that will help to break down the harmful bacteria that's in the wastewater. Once this process has been completed, the liquid water can be released from the plant directly into watercourses, such as streams.
Key Differences
Aside from the cleanliness of the effluent, there are also a number of other differences.
* Sewage treatment plants require electricity to run the air pump, however septic tanks can run power-free
* Septic tanks don't require servicing (although they do require emptying), whereas sewage treatment plants require servicing and emptying
* Septic tanks generally require emptying more frequently than sewage treatment plants
