Septic systems
Measurement schedule
The Municipality measures the sludge and scum levels in septic tanks to ensure efficient management of pump-outs. This method allows the frequency of pump-outs to be adjusted according to actual needs, in compliance with provincial regulations.
Measuring is carried out every two years, from May to October. Even-numbered civic addresses are measured in even-numbered years, and odd-numbered civic addresses are measured in odd-numbered years.
The 2026 schedule is provided for informational purposes only. The targeted sectors will be announced gradually in our newsletter and on our Facebook page.
How do I prepare for the operator's arrival?
- Clear the 2 lids of the septic tank(s) and holding tank(s).
- Make sure that the perimeter of the lid is clear by about 8 inches, up to the level of the tank, so that the lid can be tilted without difficulty.
- If your lids are made of plastic and have one or more screws, you should unscrew them and leave two partially screwed on, so that the lid cannot be lifted, but the meter can remove them quickly.
How does a septic system work?
In a nutshell, here's how a septic system works:
- Wastewater is directed into the tank via an inlet pipe.
- Solids settle to the bottom of the septic tank (what we call wheel), while oils and greases are trapped on the surface of the liquid (what we call steam).
- After settling in the septic tank, the clear water is discharged to the purifying element.
- The clear water infiltrates into the ground, where it is purified by a natural filtration process.

Septic system management
By-law 2022-410 on the management of septic systems requires homeowners to maintain functional, non-polluting septic systems to protect the environment and public health.
Which systems are affected?
- Systems that are 35 years old or older;
- Unlisted septic systems;
- Systems consisting of a septic tank made of steel, fiberglass or unapproved plastic;
- Sumps, barrels used as septic tanks, or any other type of installation that does not contain a septic tank.
How often is certification of operation carried out?
Every five (5) years, the municipality will verify the location of the purifying element and the proper operation of the septic system serving the residence. This work will be carried out by a designated firm. Notice will be sent to those concerned prior to the required inspection.
The use of a firm designated by the municipality makes it possible to obtain a better price and consistency of analysis.
Priority is given to septic systems located near bodies of water.
What elements are validated during the certification inspection?
- Verification of water level in the tank;
- Fluorescein test (dye);
- Purifier saturation test;
- Smoke test.
What should I do if a malfunction is reported?
Proof of work planning must be provided to the Municipality within 120 days of the analysis results.
A certificate of authorization from the Municipality is required for any work on a septic system. Please note that a percolation test by a technologist is required for the permit application.

Financial Assistance
For those subject to this by-law who wish to voluntarily replace their septic system, financial assistance is available.
FAQ
My septic tank needs to be emptied. What should I do?
The Municipality will send out a contractor in the weeks following the measurement. The list of septic tanks to be emptied is sent every week. Keep your lids accessible.
Please note that emptying can take up to a few months, as this is the busiest time of the year for these contractors. Don't worry, your tank won't overflow!
Once the tank has been emptied, you will receive an invoice from the municipality for the amount associated with the capacity of the septic system, as indicated below* :
- 1000 gallons or less: $219.45
- 1000 gallons to 1500 gallons: $288.75
- 1500 gallons to 3000 gallons: $414.75
- Over 3000 gallons: $829.50
*Prices shown are for the year 2025 and are subject to change without notice.
I have water in my pit. Is this normal?
If the water level is lower than the outlet pipe, this is normal. However, if the water level is higher than the inlet and outlet pipes, we recommend checking and cleaning the prefilter.
If your system is not equipped with a prefilter, it's best to contact a specialist company.
When and how should I clean the prefilter?
We recommend cleaning your septic system's prefilter every six months, in Spring and fall.
- Remove both septic tank covers.
- Remove the prefilter cartridge. You'll find it in the second compartment of the septic tank, inside the access point closest to the secondary treatment system (Ecoflo biofilter, Bionest, drainfield, etc.).
- Use a garden hose to clean the cartridge in the first compartment (the one near the house). This will allow dislodged debris to be processed.
- Replace the pre-filter cartridge in the right direction, following the arrow.
- Replace the septic tank covers in their original position.
Important: wear long clothing, gloves and goggles. Once the prefilter has been cleaned, wash your hands and change your clothes as soon as possible.
My septic tank needs replacing. What should I do?
- You must first obtain a percolation test from a technologist.
- You must then apply to the municipality for a certificate of authorization to carry out the work.
- Financial assistance may be available.
How can I tell if my septic system is defective?
There are a number of signs that may indicate that your septic system is defective. If you observe one or more of the following signs, contact a qualified professional to determine the source of the problem so that you can plan the necessary repairs:
- You can smell fumes near your septic system (sewage odor);
- Your home's wastewater disposal is slow;
- Near your septic system, the lawn is noticeably fuller, greener or longer than on the rest of the property, or spongy even in dry periods;
- Water seepage near your septic system;
- The presence of bacterial contamination or nitrates is noted when the water from your well or your neighbor's well is analyzed.
How can I reduce the frequency of pump-outs?
- Use chemicals or cleaning products that are harmful in moderation (e.g. bleach, borax, etc.).
- Avoid disposing of substances in your septic tank that do not decompose naturally or very slowly.
- There's no need to use commercial products to stimulate bacterial activity, since bacteria are naturally present in the septic tank.
Tips for proper septic tank maintenance
Certain materials can interfere with the proper functioning of your septic system, cause blockages, or reduce the effectiveness of wastewater treatment.

- Ground-up food
- Cooking oils and fats
- Liquid fabric softeners
- Disinfectants and antibacterial soaps
- Tissue paper
- Cosmetics
- Carpet cleaners or floor wax
- Toxic or flammable products
- Hair
