The Norwesco 750-gallon two-compartment septic tank is built for low-clearance burial and high-volume on-site treatment, with a preplumbed two-compartment layout and IAPMO certification for code-driven installs. It measures 92 inches long by 60 inches wide by 51 inches tall, and the low-profile body keeps the burial cut shallow while holding 750 gallons of polyethylene-tank capacity across both compartments. The 20-inch lid gives you riser-ready access for pumping and inspection. If you are weighing a single-compartment versus two-compartment design for your drainfield or treatment train, the two-compartment setup adds the second chamber for the second stage of settling before effluent moves on.
Will it work for your install?
This is a low-profile septic tank, not a chemical or hauling vessel: the spec sheet lists no specific-gravity rating, so size it strictly for water-weight septic service. Filled to 750 gallons it carries a full water weight of 6,255 pounds, and the 60.0 x 92.0-inch footprint is the dimension to plan your hole and bedding base around. Confirm the 51-inch height against your invert depth and cover requirement before you dig. The preplumbed design and 20-inch lid mean less field plumbing, but the inlet and outlet sizes and invert elevations are not listed in our spec data - confirm them on the technical drawing on this page before you cut pipe. For help matching capacity to daily flow, run the Tank Sizing Calculator or read the Tank Sizing Guide.
Compartments and access
The two-compartment build adds the second stage of settling, but our spec data does not give the per-chamber volume split - confirm the chamber division on the technical drawing rather than assuming an even 375/375 halving. The fittings record shows a single 20-inch lid, so plan on that one documented access opening serving the tank unless the drawing shows a second port; if you need two-point pumping access, verify that against the drawing before ordering. To understand why this two-compartment design is specified over a single chamber, see Single Compartment vs Two Compartment Septic Tanks.
IAPMO certification
This tank carries IAPMO certification, which matters when your jurisdiction enforces plumbing-code listing for septic vessels. We cannot confirm from the spec sheet which specific listing your inspector will require, and IAPMO and CSA B66 approvals carry different scope across US and Canadian codes - verify the accepted listing with your inspector before ordering. Our guide on Norwesco IAPMO and CSA B66 Septic Tank Approvals breaks down the cross-border scope, and if you are spec'ing this Norwesco low-profile body for hauling or field use, the Norwesco Low-Profile Hauling Tank Series guide covers field-operations and procurement detail.
Freight and ordering
This green Norwesco septic tank ships LTL freight from Shawnee, Oklahoma, quoted live to your ZIP - there is no flat shipping number because LTL rates vary by destination and accessorial needs. Get an exact number from the Freight Cost Estimator before you order, or call 866-418-1777 and we will work the quote with you. The most common mistake on a tank this size is digging the hole before confirming the 60 x 92-inch footprint and 51-inch height against your site - check the technical drawing on this page and verify your invert and cover depths first.
