This is the official product video for the Norwesco 1500 Gallon Plastic Two Compartment Septic Tank - IAPMO Certified. Full specifications, dimensions, and live pricing are on the product page.
In the quiet of the excavation... a yellow polyethylene colossus stands — IAPMO-certified, built for residential and light-commercial systems where code calls for a two-compartment design. It measures 135 inches long, 55 inches wide, and 63 inches tall... a 55 x 135 inch footprint that must be planned into the dig. Inside, two compartments separate primary settling from secondary clarification within a single tank. Filled with water for testing, it holds roughly 12,510 pounds... and depends on correct bedding, uniform backfill, and proper burial per the manufacturer instructions and the technical drawing. This is a 1500-gallon septic tank — size to flow and code, not liquid weight. Norwesco 1500 Gallon Two Compartment Septic Tank. Built for Code. OneSource Plastics.
