Enviro-Septic System Maintenance
Septic Tank
Maintenance
The septic tank preceding the Enviro-Septic System must be pumped out
regularly. Article 13 of the Q-2, r.22 regulation requires that it is pumped out
every two years for normal residential use or every four years for seasonal
applications. For more information on septic tank maintenance, verify the
current regulation, or get in touch with the municipal authorities.
If the septic tank is not emptied regularly, an increasingly large amount of
solids and grease in suspension will leave the septic tank and end up in the
treatment system. The septic tank will no longer function properly and in time
the performance of the Enviro-Septic System may be affected. This is why
periodic emptying of the septic tank is necessary.
At all times, a professional using the proper equipment must carry out the
pumping out of a septic tank
The owner is responsible to ensure his septic tank is pumped out
according to local regulations. This work should always be done by a
qualified person since it can be very dangerous to open a septic system
without first taking the necessary precautions.
Note: It is the home owner’s responsibility to make sure that at all times
the septic tank lids are in their proper position and securely fastened. A
lid that is not installed correctly can be harmful to the operation of the
Enviro-Septic System.
Pre-filter
(Septic tank
effluent filter)
The effluent filter is a device normally used at the exit of the septic tank
9
. It is
mandatory when a low pressure distribution system is used between the septic
tank and the Advanced Enviro-Septic
®
pipes.
The effluent filter must be cleaned according to the maintenance and
inspection procedures provided by the manufacturer.
Distribution
box and flow
equalizer
During normal use of your septic system the distribution box and the flow
equalizers do not need adjustment. The initial levelling during installation and
the self-levelling capability of the flow equalizers are generally enough to
maintain an equal distribution of water among the rows of Advanced Enviro-
Septic
®
pipe. However, a difference of more than 100 mm between the lowest
and highest water level in the piezometers for two consecutive measurements
indicates that the equalizers may need adjustment. A qualified person must
then carry out the adjustment(s).

The effluent filter is necessary whenever the septic tank is followed by a low pressure distribution system. It is also
mandatory in all BNQ certified septic tanks made since January 1
st
, 2009.
