What is a Sewage Treatment Plant?

A Sewage Treatment Plant is an off mains drainage system. It collects the water which then passes through an air diffuser which cleans the water which is then discarded to a watercourse.

Why should I use one?

As of 2020, it is illegal to use a Septic Tank to diffuse water, the water that passes through a Sewage Treatment Plant is also more cleaner which is better for the environment.
