The Norwesco 1000-gallon one-compartment septic tank pairs IAPMO certification with a low-profile body built for shallow burial and tight excavation depth. The tank holds 1,000 gallons in a single compartment, stands 51 inches tall, and lays out a 60 in wide x 127 in long footprint of green polyethylene. If you are sizing a residential or light-commercial septic system and grading constraints rule out a tall tank, this is the low-profile Norwesco unit to specify.
Will it work for your site?
The single compartment runs 127 inches long and 60 inches wide at a 51-inch height, so it fits where deeper tanks cannot, keeping excavation shallow and the invert reachable. The tank ships with loose plumbing, and the drawing shows the outlet plus a top-of-outlet tee that references a 1-inch dimension; see the technical drawing on this page for the outlet placement and tee detail. Because it arrives with loose plumbing, verify the outlet and pipe size against the drawing and supply the inlet and outlet tees, gaskets, and grommets to match your drain-waste-vent pipe before you set the tank and tie in your lines. Filled to capacity the tank carries roughly 8,340 pounds of water, so plan the bed, bedding, and backfill for that loaded weight. If you are still confirming gallonage against household or fixture-unit load, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Codes and approvals
This tank is IAPMO certified, which matters when your jurisdiction references the Uniform Plumbing Code for septic installations. Confirm your local plumbing authority's acceptance and required inlet, outlet, and venting details before burial. Our walkthrough on Norwesco IAPMO and CSA B66 septic tank approvals explains the certification scope and how it maps to US plumbing codes, and the tank plumbing system design walkthrough covers inlet, outlet, vent, and overflow tie-ins so the loose plumbing goes in correctly the first time.
The mistake to avoid
The most common error on a low-profile septic tank is treating it like a deep tank and over-excavating, then losing the close-to-grade advantage and creating a longer inlet drop than the design intends. Hold the bury depth the low-profile body is built for, and verify the 1-inch outlet tee reference height against the drawing before backfill so your effluent line leaves at the correct invert. For a broader look at the low-profile platform and field handling, the Norwesco low-profile series field operations guide is worth a read.
