1. Choose a designer to obtain a site analysis. (A soil test analysis done by a technologist or an engineer.)
  2. Upon receipt of the study, discuss with the designer the types of facilities that suit your needs.
  3. Choose the best option for your eco-friendly, cost-effective and durability requirements.
  4. Have plans and specifications executed according to your choice.
  5. Obtain a permit from your municipality for the septic installation you have selected.
  6. Choose from qualified installers based on a minimum of three quotes.
  7. Give a site supervision mandate.

The cost depends on various factors such as your site itself, the type of soil, ease of access, the region in which your site is located, and the number of bedrooms. For example, for a 3-bedroom home, you should get a quote anywhere between $12,000 and $16,000, all inclusive (septic tank, System O)), filter sand, filling, etc.)

Yes, the pipes will be placed perpendicular to the slope, in trenches to a maximum of 30%.

Advanced Enviro)) Septic polyethylene pipes are guaranteed for 20 years by the manufacturer.

Odors are drawn upwards and out via what is known as the chimney effect created between the roof vent and the septic system, usually a septic tank. If there are odors, they could come from a blocked roof vent (for example by snow and ice), or by winds that push down into the roof vent. These situations would recur regardless of the type of septic system used.

The filter sand does not need to be changed and the system components are guaranteed for 20 years. The technology exists since 1987 in the United States and systems installed more than 30 years ago are still in perfect condition and still treat wastewater as ecologically as when they were put in.

Unlike conventional systems, there is no possibility of clogging with the Advanced Enviro)) Septic technology. This technology promotes aerobic and anaerobic bacterial growth and these two types of bacteria control each other to avoid uncontrolled growth and clogging.

Yes. Installed in a watertight membrane, a System O)) solution can collect water at the outlet of the septic system and discharge into a sewer, ditch or watercourse (where regulations allow).

There is no maintenance required. However, some regions require annual monitoring. Check with local regulations, or find an expert in your area.

We recommend twice a year, once in the spring and again in the fall.

No, there are no mechanical parts, it is vented and does not generate any noise.

All grasses are allowed. If you are planning a vegetable garden, you may grow cucumbers, tomatoes, beans, and squash, but you must avoid root vegetables at all costs. Thinking of shrubs instead? Choose cinquefoil, spirea, weigela, lingonberry/blueberry, berberis/barberry, azalea, and rhododendron, but avoid any and all trees.

No, not at all and you must not use these. Certain products could disturb the bacterial activity that is taking place in the pit and make it less efficient. The addition of bacteria could lead to a significant liquefaction of the sludge that would affect how it settles and risk clogging your septic tank. If you really want to give an eco-friendly boost, pour in expired milk, or yogurt that is way beyond its “best-before” date. Leave the yogurt or milk at room temperature for about 24 hours before using.

Even though a System O)) installation does not require maintenance, the Government of Québec requires an annual inspection for all advanced secondary treatment technology systems. It will cost you about $90, including taxes.

The inspector, trained by a DBO Expert, will come between the months of May and August and, if you requested it, will notify you 48 hours in advance. The inspector will check the system’s piezometers and other functions to make sure everything is working properly and, if applicable, can make  recommendations. These will be left at your door.


You will not have your septic system monitored by one of our inspectors as required by article 3.3 of regulation Q-2., R. 22. Your municipality may send you a notice of compliance, subject to a fine of up to $1,500. In addition, you would lose your manufacturer’s 20-year warranty.

The system must be able to ventilate at all times so no. However, a small children’s swing set will not crush the system and can be installed. Please contact us if in doubt.

Absolutely. But piezometer plugs and the sampling device must remain accessible for inspections. The vent can be shortened to ground level in the summer while preserving access to full ventilation. It must be extended to about 1.5 m in winter and monitored to ensure that it does become buried under the snow.
