Canada Approved - Ohio

Canada-Approved Septic Tanks (CSA B66 & IAPMO Certified)
In Canada, you cannot just bury any plastic tank and call it a day. Building codes are strict and inspectors check for the stamp. If your onsite waste treatment tank does not have CSA B66 certification, you are likely failing that inspection. That is why we stock a dedicated line of CSA approved septic tanks systems designed specifically to meet those rigorous standards....

This certification is more than just paperwork. It proves these underground poly tanks can handle punishing freeze-thaw cycles and heavy earth loads without buckling. So even if you do not live north of the border, buying one of our Canada-approved septic tanks is a smart move. You are essentially getting the "heavy-duty" upgrade of our standard lineup. These are the poly septic tanks Canada relies on for deep burial, and they are often strong enough to backfill with native soil rather than expensive gravel. Whether you need to pass a strict inspection or just want superior durability, we have the toughest plastic septic tanks for sale Canada and the US have to offer.

What Makes a Septic Tank "Canada-Approved"?

When you see the CSA stamp on our septic tanks, you are getting a product engineered for superior strength and safety. Here is why these septic systems stand out:

The CSA B66 Standard
The CSA B66 Standard

This is more than a permit. It is a rigorous structural test that proves your septic tank can withstand heavy earth loads and deep burial pressures without collapsing.

Working Capacity vs Total Capacity
Working Capacity vs Total Capacity

Canadian regulations rate tanks based on the actual liquid they hold before flowing out, rather than the total volume of the shell. This ensures you are paying for usable storage space instead of empty air.

Cold Weather Resilience
Cold Weather Resilience

These are the best septic tanks for freezing climates because they are molded from high-density resin that resists brittleness. The material is designed to flex with the ground during freeze and thaw cycles rather than cracking like concrete.

Applications for Heavy-Duty & Canada-Approved Tanks

These poly septic tanks are designed for more than just meeting code; they are problem solvers for difficult job sites.

Difficult Access Sites
Difficult Access Sites

When you cannot get a dump truck full of stone to a remote property, you need septic tanks for native soil backfill. The superior strength of the "Bruiser" line often allows you to backfill with the dirt you dug up, saving time and material costs.

Failed System Replacement

If you need to replace concrete septic tank Canada based systems that have cracked or eroded, these poly tanks are the ideal upgrade. They are lighter to transport into established backyards yet immune to the corrosion that destroys concrete.

High-Occupancy Homes

For larger properties or multi-family cottages, we offer the 1500 Gallon Septic Tank Canada regulations often require. This size handles higher daily flows while maintaining the strict structural standards of CSA B66.

High Water Table Areas

The one-piece, seamless construction is vacuum-tested at the factory. This ensures your septic tank remains watertight in wet ground, preventing groundwater from leaking in and overloading your drain field.
