The Norwesco 1500 Gallon Two Compartment Septic Tank is a blue polyethylene septic tank with two molded-in manhole access points, IAPMO certified and approved for installation in Canada. It measures 135 inches long, 55 inches wide, and 70 inches tall, with two internal compartments and a manhole over each so you can pump and inspect both sides independently.
Will it work for your site
This is a 1500-gallon two-compartment polyethylene septic tank with a 55 x 135 inch footprint and a 70 inch height, so plan your excavation around all three dimensions and the burial depth your local code requires before you order. Filled to capacity with water it weighs about 12,510 pounds, which drives your backfill planning and the bearing capacity of the soil beneath the tank. Because this is a septic vessel rather than a potable or chemical tank, size it to your daily flow and bedroom count using the Tank Sizing Calculator and the Tank Sizing Guide; running the numbers up front is how you avoid an undersized install. The two-compartment split between the inlet and outlet sides is defined by the internal baffle, so confirm the per-compartment volumes against the technical drawing on this page rather than assuming an equal half-and-half divide.
Certification and approvals
This tank carries IAPMO certification and is approved in Canada, which is why it shows up under searches for an IAPMO septic tank. Approvals are jurisdiction-specific, so the most common mistake to avoid is assuming a certification automatically satisfies your local plumbing authority. IAPMO and Canadian CSA scope do not map one-to-one onto every U.S. plumbing code, and whether a single-compartment or two-compartment tank is required varies by jurisdiction. Read Norwesco IAPMO and CSA B66 Septic Tank Approvals and Single Compartment vs Two Compartment Septic Tanks before you submit your permit, and verify the approval with your county or municipal inspector.
Specifications and access
See the technical drawing on this page for the manhole spacing, the inlet and outlet invert heights, and the baffle location between the two compartments. Inlet and outlet connection sizes and any gaskets are shown on that drawing as well, so confirm them against your incoming sewer line and its elevation before ordering, and match the inverts so the tank seats at the correct grade in the hole.
