Sewage Treatment Plant Advice
How does a sewage treatment plant work?

Briefly:
A sewage treatment plant captures sewage and actively treats it using an aerobic biological process. Over a period of time, the sewage is neutralised to a very high standard of cleanliness… clean enough for the effluent to be discharged into a nearby watercourse, for example, subject to the necessary permissions. (Compare this with how a septic tank works.)
Like a septic tank, a sludge of settled-out solids will accumulate inside the sewage treatment plant, and it will then need emptying.
The size of the sewage treatment plants needs to be matched to suit the level of usage it will encounter, which depends on the number of occupants in the property and levels of use.
