The Norwesco 900-gallon two-compartment low-profile septic tank is built for sites where digging deep is not an option. At 51 inches tall on a 60 x 126-inch footprint, this Florida-approved, IAPMO-certified septic tank seats in shallow excavations where a standard-profile tank would never sit correctly. Molded in green polyethylene, it splits primary settling from a second clarifying chamber in one low-profile body.
Will it work for your install?
The two-compartment configuration separates incoming solids and primary settling from a downstream clarifying chamber, which reduces carryover to your drainfield; the linked guide below covers why that matters. Filled to capacity, the tank and its water weigh 7,506 pounds, so size your set crew and check the bearing of the bed accordingly. Key specs at a glance:
- Capacity: 900 gallons, two compartments
- Footprint and height: 60 x 126 x 51 in
- Full water weight: 7,506 lb
- Material: green polyethylene
- Access: one 20" lid (carries a hazardous-gas warning)
Confirm your excavation length and the bury depth your code requires before you order. If you are still working out whether 900 gallons matches your daily flow and required reserve, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide.
Certification and the Florida-only scope
This tank is IAPMO certified and sold for Florida only. That approval scope is the single most common mistake on a tank like this: an IAPMO listing and a state-specific approval are not interchangeable, and a tank accepted in one jurisdiction is not automatically accepted in another. Before you buy, verify that your local health department and permitting authority will accept this exact tank and its certification for your parcel. Our guide on Norwesco IAPMO and CSA B66 septic tank approvals walks through how IAPMO scope maps to plumbing codes, and single-compartment vs two-compartment septic tanks covers the differences between the two configurations.
What's included and the technical drawing
The one documented opening on this tank is a single 20" lid, and that lid carries a hazardous-gas warning — septic gases are dangerous in a confined space, so treat every access opening accordingly. Inlet and outlet penetrations, risers, and gaskets are not supplied; locate and field-fit them off the technical drawing on this page, which shows lid placement, compartment layout, and overall dimensions. The low-profile geometry changes how the inlet and outlet line up against a standard-profile tank, so plan your plumbing tie-ins from the drawing, not from a tank you have set before. For operators running these in the field, our Norwesco low-profile series field operations guide covers handling and procurement for the low-profile line.
