Step 4 – Initial backfill
•
Backfill until you reach the tank shoulder (water level inside the
septic tank).
•
It is important that the backfill material be deposited, not dumped.
Using a bulldozer for this step is not recommended.
•
Backfill material should be free of organic matter and impermeable
soil, rock, debris or particles larger than 20 mm (¾") or any object
that could damage the septic tank.
Note: It is essential to backfill evenly each side of the septic tank.
Step 5 – Riser installation
When risers are required, proceed as follows:
•
Clean the rim of the septic tank access (where the 4 holes are
located for the lag screws).
•
Place the rubber seal on the access rim.
•
Put the the riser in place, aligning the holes in the base of the riser
with the holes of the access rim.
•
Tighten the riser in place by using the 4 lag screws and washers
provided for this purpose.
Step 6 – Final backfill of the septic tank
•
When the septic tank is full of water, backfill up to the
desired height.
•
The thickness of the backfill over the septic tank must
not exceed 90 cm (36").
•
If necessary, use PSR-060 or PSR-140 risers.
•
Secure the lids on the septic tank or the risers with the
supplied lag screws.
6. Maintenance
6.1 Maintenance of the septic tank
The septic tank should be inspected and emptied regularly. For example, in Québec, the septic tanks must be emptied every two (2)
years for principal residences and every four (4) years for secondary residences. However, a by-law governing the septic tank emptying
might have been adopted by a municipality or county, therefore, it is important to consult your local regulations for prescribed
inspection and emptying frequency. It is also possible that the septic tank has to be emptied according to the scum or sludge level in
the system. Once the septic tank is emptied and the effluent filter has been cleaned (if required), fill the septic tank with water.
Note: If your home is equipped with a garbage disposal or a sewage pump, we strongly recommend emptying your septic tank more
frequently. The use of this kind of equipment increases the amount of sludge in the septic tank.
