The Norwesco 1000 Gallon Septic Tank is a yellow polyethylene septic tank for onsite wastewater systems, manufactured and shipped from Norwesco's Hanford, CA plant. It holds 1,000 gallons and measures 63 inches high by 60 inches wide by 102 inches long, giving you a 60 x 102-inch footprint to plan your installation around. This is a low, long tank, so check the 63-inch height against your burial depth and the 102-inch length against your bed run before you dig. If you are working out tank placement for your lot, the Tank Sizing Calculator and Tank Sizing Guide walk through how to match a 1000 gallon tank to your needs.
Will this Norwesco septic tank work for your system?
This is a 1,000-gallon Norwesco septic tank in polyethylene. Confirm the required capacity against your local health department's sizing requirements before you order, since septic sizing is set by code, not by preference. At full capacity, plan for roughly 8,340 pounds of water weight. A loaded tank approaching four-plus tons changes how you prepare the site: the bearing capacity of the bed and the equipment you bring to set the tank both need to account for that mass. Set the tank on a level, compacted base per Norwesco's instructions, and see the technical drawing on this page for the inlet and outlet layout.
Specific gravity and fittings
This tank carries no published specific-gravity rating. It is sold for wastewater and septic service, not for heavy chemical storage, so do not press it into chemical duty that would require an SG-rated tank. Fitting and grommet configuration is not published for this SKU either. Before you order, call us at 866-418-1777 to confirm inlet and outlet placement and gasket sizing for your plumbing tie-in, so you do not end up with the wrong adapter on delivery day.
Septic approvals and the mistake to avoid
The single biggest mistake with a poly septic tank is installing it before you have confirmed it is approved for septic use in your jurisdiction. Septic-tank acceptance is governed by state and provincial plumbing authorities, and approvals are not universal. Read Norwesco IAPMO and CSA B66 Septic Tank Approvals to understand how U.S. and Canadian code scopes differ before you commit, and verify current local acceptance with your AHJ. If you are weighing this against other Norwesco onsite tanks, the Norwesco Doorway Tank Sizing Guide covers how the 100 to 1000 gallon range maps to different applications.
Freight
