1250 Gallon Low Profile Septic Tank

The Norwesco 1250 Gallon Low Profile Septic Tank (SKU N-43572) is a polyethylene tank built wide and shallow for buried septic and low-profile hauling or pump-out roles. At just 51 inches tall on a 60 x 157 inch footprint, it holds 1,250 gallons while keeping burial depth and cover height down - which is the whole point of a low profile tank on shallow-excavation or high-water-table sites. If you are weighing this against other capacities, the Tank Sizing Calculator and Tank Sizing Guide help confirm the right size for your daily flow and field layout.

Will it work for your install

This is a 1,250-gallon Norwesco low profile septic tank molded in polyethylene. The body measures 157 inches long, 60 inches wide, and 51 inches tall, so confirm your excavation length and your available cover height before you order. Filled with water the tank carries roughly 10,425 pounds, but it ships empty and the poly shell is light enough to set into place by hand or with light equipment before you backfill - plan your excavation and handling around the empty weight, not the filled figure. Verify the dimensions line up with your incoming and outgoing pipe runs and site layout. The fitting and outlet configuration is not specified here, so call 866-418-1777 to confirm inlet and outlet placement for your pipe runs before you commit to a layout.

Service limits and the mistake to avoid

This tank carries no specific gravity rating for dense liquids, which means it is built for septic and wastewater at water density - not for chemicals heavier than water. Do not press a septic shell into denser-than-water service. The other mistake to avoid is treating any low profile poly tank as automatically code-approved for your jurisdiction. State and local septic approvals vary, so confirm the applicable listings with your authority having jurisdiction before you commit to a layout. Our guide on Norwesco IAPMO and CSA B66 Septic Tank Approvals walks through the cross-border scope of these listings versus US plumbing codes. If this tank is going into a hauling or pump-out role rather than a buried septic role, the Norwesco Low-Profile Hauling Tank Series field guide covers field operations, compliance, and procurement for the low profile series.
