The Norwesco 1000-gallon two-compartment low-profile septic tank is built for site-built and replacement installs across South Carolina and North Carolina, where IAPMO certification is the accepted approval path. Before anything else, confirm your jurisdiction: this unit is sold for SC/NC where IAPMO is recognized, and Canadian and other US approval scopes differ - if your county health department does not accept the IAPMO listing, this is not the tank to add to your cart. At 51 inches tall with a 60 x 127 inch footprint, its low-profile shape keeps the excavation shallower than a tall single-compartment tank, which matters on high-water-table lots and rocky ground. Molded from polyethylene in green, it ships with loose plumbing so your installer sets the inlet and outlet to grade on site rather than working around a fixed factory configuration.
Will it work for your septic install?
This is a 1000-gallon two-compartment tank, so primary settling and a secondary clarification chamber are handled in one vessel - the design reason a two-compartment unit gets specified over a single-compartment tank on many newer code cycles. The technical drawing on this page shows a 20-inch lid (note the hazardous-gas warning on that opening - treat every entry as a confined space) and the outlet location. Filled to capacity with water it carries approximately 8,340 lb, so plan your bedding, anti-flotation, and backfill for that loaded weight against the shallow 51-inch profile. The low-profile geometry follows the same series approach Norwesco uses across its hauling and low-profile line, and the IAPMO listing is what makes it placeable under SC and NC plumbing approval.
Confirm before you order
Because the plumbing is loose, inlet and outlet grommets and gaskets are not included - they are sized and set on site to match your tie-in grade, so plan that hardware into your install ahead of delivery. The single most common mistake on this tank is assuming IAPMO covers every jurisdiction; read the Norwesco IAPMO and CSA B66 septic approval breakdown and verify your county accepts the listing before you dig. For the tie-in itself, the inlet, outlet, vent and overflow walkthrough covers vent and drain detailing. If you are still deciding chamber count or capacity, see single vs two-compartment septic tanks and the Tank Sizing Guide, and for low-profile field handling the low-profile series field operations guide.
Freight and ordering
This tank ships LTL freight from Norwesco's Griffin, GA plant, quoted live to your ZIP - a 60 x 127 inch low-profile septic tank moves on a dedicated freight carrier, not parcel. Get your number on the Freight Cost Estimator, size your install with the Tank Sizing Calculator, or call 866-418-1777 to confirm IAPMO scope for your county and lock in your order.
