Septic tank
Effluent filter
Upon the maintenance visit, the Bionest authorized representative will clean the effluent filter.
Cleaning of the effluent filter is normally required twice a year, but may require additional
cleaning, should an important deposit be noticed on the effluent filter.
Emptying
For a system serving a six (6) bedroom or less dwelling or a building with a daily flow rate less
than or equal to 3,240 L/day, you have a legal obligation to comply with the Q-2, r. 22 Regulation
respecting wastewater disposal systems for isolated dwellings which states that, for a building or
residence used on a regular basis, the septic tank must be emptied at least once every other year
and, for a building or residence used on a seasonal basis, the septic tank must be emptied at least
once every four (4) years or when sludge accumulation is equal to or exceeds 30 cm or when the
foam layer thickness is equal to or exceeds 12 cm. Your municipal authorities may have adopted
a specific by-law regarding the cleaning of septic tanks which involves their annual inspection.
MDDELCC regulation http://www.mddelcc.gouv.qc.ca/eau/eaux-usees/domestique/chap3.pdf,
(French) section 3.4.7, states that, pumping the septic tank of a system which treats over 3,240
liters per day must be done when needed, when the total measured sludge and foam accumulation
exceeds 40% of the liquid height. If no measurement, a yearly emptying of the septic tank is
recommended for those buildings operating year round and every other year for those buildings
4
operating on a seasonal basis.
Pumping of any septic tank must be performed by a specialized firm.
WHEN EMPTYING OF THE SEPTIC TANK, PLEASE DISCONNECT THE BIOLARM®
POWER SUPPLY; THIS WILL STOP THE RECIRCULATION PUMP AND ALARMS. ONCE
THE EMPTYING IS COMPLETE AND BEFORE RECONNECTING THE BIOLARM®, MAKE
SURE THE SEPTIC TANK IS COMPLETELY FILLED WITH CLEAR WATER.
