A septic tank works in four basic steps.
How a septic tank works.
A septic tank consists of one or more concrete or plastic tanks of between 4000 and 7500 litres 1 000 and 2 000 gallons.
One end is connected to an inlet wastewater pipe and the other to a septic drain field generally these pipe connections are made with a t pipe allowing liquid to enter and exit without disturbing any crust on the surface.
Proper septic tanks should be fitted with an effluent filter or tank outlet filter.
Inlet baffles need to be in place to direct flow into the tank downward to allow for settling of solids to occur and to prevent the short circuiting of water and solids directly through the tank.
The inlet pipe collects the water waste in the septic tank long enough that the solid and liquid waste is separated from each other.
The tank is connected with two pipes for inlet and outlet.

A well maintained septic system is odour free and requires less emptying.
This is installed in the outlet of the tank and helps prevent anything other than liquid getting into the leach field or clogging the outlet pipe.
Septic tank outlet filter add on.
We also recommend septic tank outlet filters installed at the tank outlet tee to extend the drainfield life.
This can only be determined by looking in the tank and in some cases we have to pump the tank first in order to see inside.
