The Norwesco 750 Gallon Two Compartment Septic Tank is built for installs where vertical clearance is tight. At 51 inches tall on a 60 x 92 inch footprint, this low-profile polyethylene tank drops into shallow excavations where a taller dome-top tank won't fit, while still holding a full 750 gallons across two internal compartments. It's IAPMO certified and ships with loose plumbing, so your installer sets inlet, outlet, and baffle tie-ins to your site plan. If you're weighing one chamber against two, the single compartment vs two compartment septic tank guide explains how the two designs differ.
Will it work for your site
This is a green molded-polyethylene low-profile septic tank measuring 51 in high, 60 in wide, and 92 in long, with a 60.0 x 92.0 inch footprint to lay out your excavation. Plumbing is loose rather than pre-installed, so inlet, outlet, vent, and overflow tie-ins are set during installation - the tank plumbing system design walkthrough covers inlet, outlet, vent, and overflow drain tie-ins so the layout is right the first time. Because the plumbing is field-supplied, confirm grommet, gasket, and pipe-size requirements against the technical drawing before ordering fittings - the 20 inch lid is the only pre-defined opening on the tank. Note that with a single 20 inch lid serving a two-compartment design, pump-out and service access for the second chamber follow the partition and riser detail shown on the drawing, so don't assume a separate lid per compartment. See the technical drawing on this page for lid placement, compartment partition detail, and individual compartment volumes.
Weights and certification
Filled with water at capacity the tank carries about 6,255 lb, so plan bedding, backfill, and anti-flotation provisions for that load. That figure is the water-full weight, not the empty handling weight - check the technical drawing or spec sheet for the empty tank weight before deciding whether this is a hand-set or machine-set tank on your site. Not sure the 750 gallon size matches your daily flow? Run the numbers with our Tank Sizing Calculator and cross-check against the Tank Sizing Guide. On certification, this tank is IAPMO certified, which matters because septic approvals are jurisdiction-specific. Before you buy, confirm what your local plumbing authority accepts - our Norwesco IAPMO and CSA B66 septic tank approvals guide walks through the IAPMO scope versus US plumbing codes and the Canadian cross-border picture.
