How do I maintain my system between pump-outs?
- Clean the effluent filter twice a year.
- Use only biodegradable products.
- Avoid large amounts of water in a short period of time.
- Do not flush anything other than organic waste down the toilet.
Can I use a garbage disposal?
No. Using a garbage disposal significantly increases the amount of solids in the tank and accelerates saturation. It is strongly discouraged in a septic system.
What should I do if septic odors are present?
- À Indoors: Check floor drains, wax seals, vents, and plumbing.
- Outdoors: Check the tank lids, roof vent, and make sure the leaching field is not saturated.
Can I skate or store snow on the leaching field?
No. Any activity that compacts the soil (vehicles, foot traffic, snow accumulation) reduces soil oxygenation, prevents evaporation, and can cause damage.
Why should I have my tank pumped out?
Pumping removes the sludge that accumulates at the bottom of the tank. Without regular pump-outs, this sludge can block the system, cause backups, or saturate the leaching field. A tank used year-round should be pumped every two years (or according to municipal regulations).
What is hydraulic overload?
Hydraulic overload occurs when too much water enters the system in a short amount of time (e.g., several baths and loads of laundry within the same hour). This prevents proper settling, pushes solids toward the leaching field, and accelerates its saturation. Large water usages should be spaced out, and water-saving devices should be installed.
Is it necessary to use biological additives?
Although not mandatory, quality biological additives (such as Bio-Clean) can improve waste digestion, reduce odors, and extend the lifespan of the system. They are a better alternative to chemical drain cleaners.
What are the main types of septic systems?
There are several wastewater treatment technologies adapted to different soil types and property realities. Here is an overview of the most common systems installed in Quebec:
Conventional System
The traditional septic system includes a septic tank followed by a leaching field (trenches, filter bed, etc.). It is simple, reliable, and cost-effective, but requires well-drained soil. It has no mechanical components and relies solely on natural infiltration and bacterial action.
Advantages: Low maintenance, cost-effective
Bionest
The Bionest system is an advanced secondary treatment system. After the septic tank, wastewater is treated in a reactor containing a fixed media where bacteria attach. With continuous aeration and efficient filtration, it breaks down organic matter and significantly reduces contaminants.
Advantages: Excellent treatment quality, compact
Écoflo
Écoflo is a passive biological filter using a natural filtering medium such as peat moss or coconut fiber. It can be installed with a standard septic tank or as a compact system.
Advantages: Eco-friendly, silent, low energy consumption
Holding Tank (sealed)
A sealed tank has no outlet and retains all wastewater (often used where sites are non-compliant). It must be pumped out regularly.
Advantages: No soil infiltration, suitable for sensitive areas
System O))
System O)) is a passive, non-mechanical solution that treats wastewater using perforated pipes three times wider than traditional conduits. These components promote aeration and bacterial growth, enabling efficient treatment directly in the soil.
Advantages: Small footprint, high-performance treatment
Hydro-Kinetic (Norweco)
An advanced continuous-treatment system with active aeration. Wastewater moves through several compartments where pollutants are reduced through mechanical oxygenation.
Advantages: High performance, ideal for difficult soil conditions
What is the purpose of a filter?
The effluent filter is located in the second compartment of the septic tank. Its purpose is to capture suspended organic solids to prevent them from reaching the leaching system, which could cause premature saturation. It must be cleaned twice a year, ideally in the spring and fall.
What are grey waters?
Grey water comes from sinks, showers, washers, and kitchens—but not toilets.
Includes:
- Kitchen water
- Bathroom sinks, showers, tubs
- Laundry water
- Household appliances
- Floor drains (garage, basement, etc.)
These waters are different from black water (toilet wastewater), but must still be properly treated to meet environmental standards and prevent soil or groundwater contamination.
Can a water softener be connected to the septic system?
No. Discharge water from a softener contains mineral salts that damage concrete, dry out plastic components, harm bacterial activity, and may overload the system. It must be redirected elsewhere.
Can I plant trees over my tank or leaching field?
No. Tree and shrub roots seek moisture and can damage pipes or block absorption trenches. Keep at least a 2-meter clearance.
What should I do before the technician comes for pumping?
Make sure both tank lids (solids side and liquids side) are accessible (minimum 50 cm diameter).
If not, consider having risers installed.
What are the signs of a failing system?
- Wastewater backup in the house
- Strong odors indoors or outdoors
- Unusually lush vegetation over the leaching field
- Slow drainage from plumbing fixtures
- Water pooling on the ground surface
- Well contamination (nitrates, coliforms)
Which products should be avoided?
Avoid products containing chlorine, ammonia, antibacterial agents, solvents, or overly strong detergents. Choose biodegradable products instead. Do not use a garbage disposal, and never flush wipes, cigarette butts, oils, medications, or sanitary products down the toilet.
What should I do if the pump station alarm goes off?
This does not necessarily mean the tank is full. First, check the electrical supply to the pump. If everything looks normal, contact Septique DD for a pump or system inspection.
How do I choose the right system?
The choice depends on several factors:
- Soil type
- Lot size
- Proximity to groundwater or lakes
- Number of occupants
- Compliance with environmental regulations
With the help of our experts, Septique DD will guide you in selecting the system that best fits your property and your needs.
What is an effluent filter?
An effluent filter is a component installed at the outlet of your septic tank, specifically in the liquids compartment. Its role is to capture suspended solids before they reach the leaching element (such as the leaching field).
Why is this important?
Because these solids can, over time, create a buildup of biomass (undigested organic waste) that risks blocking or saturating your system. The filter acts as a critical protective barrier.
Does it require maintenance?
Yes, absolutely. For the filter to remain effective, it must be cleaned about twice a year, usually in the spring and fall. Without this maintenance, it can clog and affect the performance of your septic tank.
Good to know
Certain issues can lead to frequent filter blockages, such as:
- A tank that is too full or experiencing hydraulic overload
- Use of a garbage disposal
- Poor bacterial activity in the tank
- Discharge from a water softener
- General lack of system maintenance
At Septique DD, we can install, maintain, and explain the operation of your effluent filter to help ensure the long-term health of your septic system.
