Treatment process detail

Effluent filtration is standard for all EPIC tanks and is a key part of the design.
The integrated outlet filter traps fine solids preventing them from leaving the tank and blocking the drainage field. This increases the lifespan of the drainage field and therefore the lifespan of the complete septic system.

Shallow design

EPIC is a shallow dig septic tank making it easier and cheaper to install than conventional “onion shaped” septic tanks.
The shallow design makes it easier to install in unstable conditions such as sandy soils.


EPIC has been designed to make installation as simple, quick and low cost as possible.
Its compact design and robust construction mean that it is suitable for installation by nearly all contractors. It does not have to be installed by an approved contractor.
On dry sites, the EPIC septic tank can have a granular backfill rather than concrete.

About Septic Tanks

Septic tanks are like sewage treatment plants – just on a smaller scale.They are chambered,vary in size (typical capacities 2800-5000 litres) and are used for properties with no mains drainage connection.Septic tanks have an inlet from the waste pipe of the property and an outlet into the drainage field or soak-away. The term “septic” refers to the process of anaerobic bacteria (does not need lots of oxygen) breaking down and mineralizing waste discharged into the tank.
When waste enters the first chamber, solids settle and a surface scum forms a 'crust'. Settled solids then get digested by the bacteria and the remaining liquid waste enters the second and third chambers where more settlement of the waste happens – are you keeping up? Finally, excess water flows out via the outlet to the drainage field for further treatment from the soil. Any remaining solid waste must be removed periodically by tanker.
