About Sewage Treatment Plants

Sewage treatment plants are rapidly becoming the non-mains drainage replacement of choice for septic tank owners. This doesn't surprise us since they represent a better environmental and durable response to the challenge of not being connected to mains drainage.
Sewage Treatment Plants harness the process of aerobic digestion of bacteria - the most common form of life on the planet. As solid matter settles it gets decomposed by oxygen (hence aerobic) fed bacteria – the coarser solids need longer to be worked on and sludge of settled solids accumulates inside the plant, which will need removing at intervals (usually annually) but dependent upon the specific size and type of plant.
Largely unseen, quiet and watertight these subterranean units receive all the sewage water and waste from your home or business. They are usually made from glass reinforced plastic (GRP) so they're durable and robust. At the end of the bacterial digestion process is an effluent which is surprisingly clean and can be discharged into the ground (soakaway) or a nearby watercourse. This of course is subject to legislation and we recommend you take some time to understand the regulations that are involved.
