Installing Sewage Treatment Plants

Sewage treatment plants are generally seen as the replacement for failing septic tanks. As it is becoming increasingly common for local councils to require increasing ecological standards from septic systems, sewage treatment plants are becoming the first choice for sewage treatment thanks to their eco-friendly drainage process. Sewage treatment plants purify the waste thoroughly, eventually emitting almost clean water. Therefore, they are a more environmentally friendly sewage treatment option, hence why they are fast becoming a preferred method of drainage.

Sewage Treatment Plant Installation FAQ’s

How do sewage treatment plants work?

A Sewage Treatment Plant consists of 4 main operations:

Within the tank:
Solid waste is broken down by bacteria and self-cleans
The result is filtered into the liquid waste.


  • Aeration is achieved by injecting compressed air into the liquid section, which generates bacteria.
  • This bacteria then works to clean the liquid effluent to almost drinking water standards. However, you must ingest this.

The cleanliness of the liquid sewage exiting the Sewage Treatment Plant has been approved by the Environment Agency to allow for dispersal into a running ditch, streams and lakes with flowing water. Therefore, this provides an eco-friendly alternative to filtering raw sewage through the ground. However, where any of these options are not available the clean effluent should go into a new drainage field and, in extreme cases a bore hole with the appropriate permit from the EA.

What type of sewage treatment plant do I need?

The type of Sewage Treatment Plant you need depends on a number of variables: the size of property, how many occupants, domestic or commercial, availability of dispersal medium and cost.
