2. Sizing and location
For residential systems, determine the size of the septic tank required according to the number of bedrooms in the home. To find
which tank is required, refer to the regulations or standards that apply in your region, state, province or country (the same applies for
the installation).
To improve the performance of any septic installation and extend the life of the treatment system, we recommend using a larger septic
tank than that prescribed. This also allows for the eventual addition of extra bedrooms without having to replace the existing septic
tank.
Location standards
Please refer to your local regulations for minimum distances.
3. Operation guidelines
The following recommendations are intended to ensure the optimum treatment efficiency and operation of your septic installation as
well as maintain it in proper working order.
It is not recommended to discharge any of the following substances into the septic tank:
• Oil and grease (engine oil, cooking oil, etc.);
• Wax and resins;
• Paints and solvents;
• Any kind of petroleum product;
• Any kind of pesticide;
• Any kind of septic tank additive;
• Any kind of toxic substance;
• Anything not easily biodegradable (e.g. coffee beans, cigarette butts,
• sanitary napkins, tampons, condoms, cotton swab, etc.).
It is important that all parties involved (installer, landscaper, owner, snow removal service, etc.) comply with the
following guidelines:
• Never install a septic tank in a place where the groundwater table can reach its base (otherwise, drain pipes could be required).
• Never install a septic tank in clayey soil.
• The profile of the lot must be such that surface run off flows away from the septic system.
• The septic tank must be watertight and be used for disposal of domestic wastewater only.
• Never connect a drain pipe, roof gutter, sump pump or air conditioning drain to your septic system.
• Never cover or bury the access lids of the septic tank. It needs to be accessible for maintenance and emptying.
• Respect the minimum distances prescribed by regulations.
• Backfill thickness over the septic tank must not exceed 90 cm (36").
• Never enter the septic tank.
• Install the septic tank where there is no motorized traffic.
• Never drive vehicles or place objects weighing over 200 kg (450 lbs) within 3 m (10') of the lids.
• Never overload the soil (ex: blown snow, embankment/slope) within 3 m (10') of the lids. The overload could damage the system.
• Never discharge water from a water softener backwash in your septic system.
• Never discharge water from a spa or pool backwash into any of the components of your septic system.
• Never discharge water from a recreational vehicle (camping trailer, caravan, etc.) into any of the components of your septic system.
• Never use an automatic bowl cleaner.
• The home must be equipped with an air vent that is in proper working order and complies with the applicable standards.
