The Norwesco 1000 gallon low-profile septic tank is built for the install where vertical clearance is the constraint: at 51 inches tall over a 60 by 127 inch footprint, it slides into shallower excavations than a taller 1000 gallon tank would allow, while the single-compartment molded polyethylene body carries the full 1000 gallon load. It ships with loose plumbing and a side inlet, so you set the connection geometry to match your inlet and outlet runs on site. If you have been searching "1000 gallon low profile septic tank" and weighing depth against capacity, this is the tank that solves that trade-off.
Will it work for your install?
This is a one-compartment septic tank molded in green polyethylene, 1000 gallon capacity, with a low-profile design and a side inlet. Footprint is 60.0 by 127.0 inches and overall height is 51 inches, so confirm your bury depth and inlet/outlet invert elevations against those numbers before you dig. Because the inlet is on the side rather than the top and the plumbing ships loose, check the molded inlet boss elevation on the technical drawing against your incoming sewer line invert before excavating, then orient and trim the inlet and outlet to your line layout. For matching tank size to daily flow and field loading, run the numbers in our Tank Sizing Calculator and read the Tank Sizing Guide. Our Tank Plumbing System Design walkthrough covers tying in the inlet, outlet, and vent correctly on a loose-plumbing tank like this one.
Weight, handling, and approvals
Full, the contents add up fast. At 1000 gallons of water-equivalent the tank distributes roughly 8,340 pounds across the 60 by 127 inch footprint, so the bedding and backfill have to support that load uniformly along the entire 127 inch length to prevent settling or distortion. Septic approvals are state- and code-specific: before you specify this tank, confirm it is accepted in your jurisdiction. Our guide on Norwesco IAPMO and CSA B66 septic tank approvals lays out where the certifications apply and how cross-border scope compares to US plumbing codes. Fitting and grommet sizes are not specified in our catalog data for this SKU, so see the technical drawing on this page for the molded inlet, outlet, and lid layout, or call 866-418-1777 to confirm the ports before ordering connectors.
The mistake to avoid
The low-profile shape is the whole point of this tank, and it is also where installs go wrong: a wider, longer, shallower body needs level, well-compacted bedding across the entire footprint, because any soft spot under that 127 inch length concentrates load and can rack the tank. Do not treat it like a tall narrow tank that loads more vertically. Set it level, support the full footprint, and verify your inlet and outlet inverts before backfilling.
