EPIC Septic Tanks
EPIC Septic Tanks are manufactured by WTE for properties that require a Septic Tank and not a sewage treatment plant.
EPIC Tanks are compact and lightweight making installation simple.
Every EPIC Septic Tank is also fitted with a WTE Drain-X effluent filter to significantly reduce particles leaving the tank and blocking up the drainage field.

How the EPIC Septic Tank Works
Wastewater from the building enters the EPIC Septic Tank via the 110mm inlet pipe connection.
Solids are separated from water inside the EPIC septic tank by gravity. Heavy solids sink to the bottom of the tank and oils and fats rise to the surface.
The water inside the tank is filtered through a Drain-X effluent filter (see below) before flowing out of the tank and into the drainage field through the 110mm outlet pipe.
Extension Turrets
EPIC Septic Tanks can be ordered with 100mm and 200mm Extension Turrets for sites with deeper drainage pipes.
Shallow Dig Installation
Compact septic systems like EPIC are ideal for properties with no connection to mains drainage and low water tables that permit Drainage Fields.
Installation of EPIC Septic Tanks is very simple due to the low profile design. This reduces the excavation depth considerably compared to most other Septic Tanks.
Drain-X Septic Tank Effluent Filter
Like all septic tanks, the effluent from EPIC septic tanks is discharged to a drainage field or drainage mound.
EPIC septic tanks have a Drain-X filter installed in the outlet of every tank.
Drain-X septic tank effluent filters greatly prolong the life of the drainage field by trapping physical deposits and preventing them leaving the tank and blocking up the drainage field.
The filter is easily cleaned by a suction tanker when the tank is emptied.
EPIC Lightweight Septic Tank Sizing
How to size your EPIC septic tank:
The minimum size (volume) a septic tank can be is dictated by Building Regulations Section H2.
A septic tank must have a minimum working volume (volume of water) of 2,700L for up to four people. For every additional person, the volume is increased by 180L.
The number of people is determined by the number of bedrooms in the property:
1 bedroom = 2 people
2 bedrooms = 4 people
3 bedrooms = 5 people
4 bedrooms = 6 people
5 bedrooms = 7 people
6 bedrooms = 8 people
Sizing Example
4 Bedroom House = 6 people
6 = 4+2
2,700L + (2x 180L) = 3,060L
A 4 bedroom house requires a septic tank with a minimum volume of 3,060L
