Designed for permanent sub-grade installation, poly (plastic) septic tanks are perfect for many applications. Available in dual compartments starting at 500 GAL to 1500 GAL. Single compartment holding tanks starting at 125 GAL to 1500 GAL.
Poly Septic Tanks are stronger, easier to install, and less costly than old-fashioned concrete septic tanks. They offer the quality construction and safety you expect. Manufactured from high-density polyethylene with U.V. inhibitors, these tanks utilize a horizontal flow designed for below-ground installations up to 36 inches.

The baffle system slows the flow of wastewater and directs it to the middle of the tank so wastewater can separate from solids. An outlet baffle allows the partially treated liquids to flow out for further treatment. Advantages of this baffle design include added strength, versatility, and ease of installation. Plastic Septic tanks are available in one-compartment and two-compartment designs. Manufactured for containment of liquids up to 1.7 specific gravity. These tanks are designed and manufactured to meet wastewater treatment system standards. 1000, 1250, and 1500 gallon double-compartment septic tanks have been tested by IAPMO to meet the IAPMO/ANSI Z1000-2013 and CSA B66-2016 standards.

You can find a thorough breakdown of the Ontario building code, calculation tools, and more on our blog post How to Calculate the Right Size Septic Tank! Below is a condensed version with some of the basics to help you get started.
House Size: As a general rule, your square footage can be a guide to help you assess what size septic tank you need. The minimum requirement in Ontario is 3,600L (950 USG). A 1,000 USG Poly Septic Tanks can service houses up to 1,500 square feet.
House Occupancy Rate: Simply put, the number of people living in your home will influence your septic tank needs. The average person produces an estimated 150 Litres (40 USG) of wastewater daily. A family of two will manage with a much smaller tank than a family of 5.
Additional Wastewater Producers: If your property has any additional features that produce wastewater, be sure to include them in your calculations so that your septic system can be maintained efficiently. Some examples are additional toilets, bathrooms, showers, multiple kitchens or multi-unit houses, hot tubs and pools.
Properly installing your Poly Septic Tank will minimize the risk of future complications or damage. Below are some of the considerations to review prior to installation.
Authorization: You must have a permit to install a septic tank on your property. Improper installation can reduce underground water quality and create a health hazard to those who use it.
Soil Type: Your leach field needs to be composed of soil that will effectively drain your treated sewage. High amounts of gravel and sand will drain better than soil containing large amounts of clay. If your soil is too dense to efficiently drain, it could lead to a blockage of your septic system.
Landscaping: Avoid installing your Poly Septic Tank near your home, trees, or any other significant obstructions to avoid causing damage to your drainage pipes, or even the tank itself. The septic tank should be at least 5 feet from such structures, and its lid should always be secure.
Poly Septic Tanks should be emptied at least once every 3-5 years. This is a great way to maintain the health of your septic system while ensuring your tank doesn’t overflow. Overflowing or leaking can cause environmental damage and pollution.
There are five easy indications that your septic tank is reaching capacity.
- If your drains or toilet are slow to empty when used.
- You’ll start to notice bad odours in your drains, toilets, or around your yard. As the tank fills, the space for gases inside your septic tank is reduced, causing a sewage smell.
- Your yard above the septic tank will be more vibrant and lush than other areas on your property. Excess waste can create fertilizer for your lawn but can become unsafe and hazardous quite quickly.
- Mucky or standing water on your property, specifically near your septic tank. This indicates that the septic tank is overwhelmed and may be approaching a sewage backup.
- Finally, the worst-case scenario is a sewage backup into your home. As expected, this can create an emergency situation and costly repairs to your home and septic system.
*Always check with your municipal requirements prior to installation.
