Function and operation
____________________________________________________________________
Start using the Septic Tank
When the installation is done the Septic Tank is almost ready to get started. First make a
quick check that it is filled with water up to the outlet pipe. If not, fill it all the way up.
During first week of usage make a few checks that sewage comes in and water goes out and
the level is intact to ensure the whole system works properly.

Emptying and refilling the Septic Tank
The Septic Tank must be emptied in time to prevent potential escape of sludge out to the
infiltration. It is very important the Septic Tank is filled up with water directly after sludge
emptying. The Septic Tank must never be empty during longer time while installed or refilled
only with sewage water.
Note:
Do not flush down any other waste than grey water.
The main task of the Septic Tank is to settle sludge from water.
Incoming water and sludge arriving via piping from e.g. a house is
moving slowly through the two chambers inside.
The two chambers are communicating via specific holes placed at a
certain height in the smaller chamber two. Thereafter the cleaned water
is leaving the Septic Tank via the outlet pipe alternatively using a pump.
Avoid discharge large amount of water in a short time from e.g. a
bathtub. Avoid oil and fat from cooking.
Do not flush down strong chemicals or toxins.
Note:
The Septic Tank does not work if it is not filled with water all the
way up to the outlet pipe. If it is not filled there is a risk the
sludge will not stay in intended chamber and later on can clog
the infiltration.
Note:
A good routine is to note the dates of emptying.
