The Norwesco 1250 Gallon Low Profile Septic Tank is built for installs where digging depth is the constraint. At 51 inches tall on a 60 x 157 inch footprint, this green polyethylene tank holds 1,250 gallons while sitting in a shallower excavation than a taller-profile tank of the same capacity. If you are weighing this against a standard-height septic or hauling tank, the low-profile geometry is the whole point: more bury length, less depth.
Does it work for your install?
This is a polyethylene low profile septic tank, 51 in high, 60 in wide, and 157 in long. Per the technical drawing on this page, it shows an OUTLET and a 1" top-of-outlet tee location; the listing data covers the outlet side only, so confirm the inlet tee, access ports or risers, and any grommet or pipe-connection details against the drawing and your local code before you set the tank and tie in your plumbing. Filled with water it weighs roughly 10,425 lb, and on a 157-inch bury length that loaded weight makes uniform bedding across the full footprint of 60.0 x 157.0 in matter more than on a compact tank, since uneven support under a long, shallow shell is the failure mode to design out. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 1,250 gallons matches your daily flow and required working capacity.
Approvals and the mistake to avoid
The most common mistake on a Norwesco low-profile septic tank is treating septic approval as automatic everywhere. Septic tank acceptance is set state by state and, across the border, by Canadian plumbing codes, so confirm that this model is approved for your jurisdiction before you order and dig. Our guide on Norwesco IAPMO and CSA B66 Septic Tank Approvals walks through US plumbing-code scope versus Canadian cross-border requirements, and the Norwesco Low-Profile Series field operations and procurement guide covers the practical side of speccing and placing these tanks. Note that this is a septic and effluent tank, not a chemical-storage tank, so if your application needs a higher specific-gravity rating, this is not the model for it.
Freight
This low profile septic tank ships LTL freight, quoted live to your ZIP from the nearest Norwesco plant. It is produced in Shawnee, OK and Washougal, WA, so your rate depends on which plant serves your delivery address: West-of-the-Rockies addresses generally route from Washougal, while Central and Eastern destinations route from Shawnee, and a buyer in WA, OR, or ID will see a very different number than one served out of OK. Get a real number before you commit using the Freight Cost Estimator, or call us at 866-418-1777 and we will quote the tank to your ZIP and confirm lead time. Listed price is before freight; freight is quoted separately to your address.
