Sewage Treatment Systems

A sewage treatment system, as the name suggests, provides full treatment of incoming sewage to a level that the treated effluent can discharge directly into a watercourse (ditch, stream, culvert etc.)

The method of treating the sewage differs slightly between different systems, but the basic processes are: sewage enters the system - bacteria inside the tank begins the treatment process - solids that cannot break down settle into a sludge - treated liquid waste rises and discharges out of the system. The settled sludge builds up over time and requires emptying from a licensed waste removal contractor. All sewage treatment systems that we supply require some form of power, either for a motor that rotates media discs, or an air blower that aerates the sewage - many systems also come with a control panel and alarm.

Please note we can only deliver sewage treatment systems to the mainland UK.
