The Norwesco 1250 Gallon Low Profile Septic Tank is built for the jobs where digging deep isn't an option. At just 51 inches tall on a 60 x 157 inch footprint, this single-compartment polyethylene tank clears high water tables and shallow bedrock where a standard-height 1250 would force a deeper hole. It ships with loose plumbing so your installer sets the inlet and outlet to match your system, and it carries IAPMO certification for code-driven septic installations - the linked approvals guide also covers its CSA B66 Canadian scope for cross-border work.
Will it work for your install?
This is a one-compartment, low-profile septic tank holding 1,250 gallons, molded in green polyethylene by Norwesco. The footprint is 60 inches wide by 157 inches long with an overall height of 51 inches. Confirm your trench can take the 157-inch run before you order, since a loose-plumbing septic tank delivered LTL can't be returned easily once it's on the ground. The plumbing arrives loose rather than pre-installed, which lets your installer position fittings to the inlet and outlet inverts your design calls for. For sizing against household load or daily flow, run your numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before committing to a footprint. The tank plumbing system design walkthrough covers how the inlet, outlet, vent, and overflow tie together so the loose plumbing goes in correctly the first time, and for any solids-handling outlet questions the outlet sizing and bridge-free geometry guide walks the math. Dimensions and fitting locations are shown on the technical drawing on this page.
Weight, freight, and getting it to the site
Filled to capacity with water this tank carries roughly 10,425 pounds, so plan the burial, backfill, and bedding for a fully loaded low-profile shell. Empty, it moves as an oversized LTL freight shipment. It ships from Norwesco's plant in Lancaster, Ohio, and freight is quoted live to your ZIP rather than bundled into the list price. Get a number before you order with the Freight Cost Estimator, or call 866-418-1777 and we'll quote the run to your delivery point.
The mistake to avoid
The most common error with a low-profile septic tank is treating the IAPMO listing as universal local approval. IAPMO certification establishes the tank's standing under model plumbing codes, but Canadian and cross-border installs and some jurisdictions look for additional approvals - the Norwesco IAPMO and CSA B66 septic approvals guide breaks down exactly what the listing does and does not cover, including the CSA B66 Canadian scope. Confirm your county or province accepts this tank for the intended septic use before excavation. The second trap is setting the inlet and outlet inverts wrong on the loose plumbing; verify them against your system design and the drawing on this page. For operators running a fleet of these shells, the Norwesco low-profile series field guide covers procurement and field handling.
