The Norwesco 1250 Gallon Two Compartment Low Profile Septic Tank (SKU N-43532) is an IAPMO-certified, two-compartment polyethylene septic tank offered for Florida installations where burial depth and cover restrictions make a low-profile body the right call. The three numbers that drive your dig and your offload: a 51-inch low-profile height, a 60 x 157 inch footprint, and roughly 10,425 pounds of water weight at full capacity. The tank spreads its 1,250 gallons horizontally instead of going deep, keeping the lid closer to grade on sites with high water tables or shallow rock, while the two-compartment design separates primary settling from secondary clarification so solids stay put before effluent moves toward the drainfield.
Will it work for your site?
Lay this out as a Norwesco low-profile septic tank rated at 1,250 gallons, molded in green polyethylene and carrying IAPMO certification. Plan your set point around the dimensions: 51 inches high, 60 inches wide, and 157 inches long, with that 60.0 x 157.0 inch footprint to lay out in your excavation. Size your bedding, backfill, and lifting equipment around the loaded weight - about 10,425 pounds of water filled to capacity - not the empty shell, since the long, shallow body needs even support along its full length. If you are deciding between configurations, our Single Compartment vs Two Compartment Septic Tanks guide walks through when the two-compartment layout earns its keep.
What's included, and what to plan separately
The access provided is a 20-inch lid that carries a hazardous gas warning - septic gases are dangerous, so treat every opening with confined-space precautions during installation and service. That lid is the only fitting in our supplied data for this tank: inlet and outlet sanitary tees, gaskets, and riser or lid-extension components are not listed here, so plan and source those separately rather than assuming a turnkey kit. See the technical drawing on this page for the lid placement and overall geometry, and match it against your inlet and outlet invert elevations so the tank sits correctly relative to the drainfield.
Florida certification and code scope
This unit is a Florida-only, IAPMO-certified septic tank, and that matters because septic approvals are jurisdiction-specific - a tank accepted under one state's plumbing code is not automatically accepted everywhere. Before you order, confirm the certification matches what your local Florida health department or permitting authority requires for this capacity and configuration. Our write-up on Norwesco IAPMO and CSA B66 Septic Tank Approvals explains how IAPMO scope works versus state plumbing codes, and the Norwesco Low-Profile Series field and procurement guide covers handling these long, shallow bodies in the field. If you are still confirming gallons for your daily flow and household size, run the numbers with our Tank Sizing Calculator and read the Tank Sizing Guide before committing to a capacity.
