This is the official product video for the Norwesco 15000 Gallon HDPE Underground Liquid Storage Tank. Full specifications, dimensions, and live pricing are on the product page.
From beneath the earth... a white polyethylene below-grade vessel arrives where concrete and steel stop making sense. This is a 15,000-gallon underground HDPE storage tank — 511 inches long, 101 inches wide, 107 inches tall... a 42-foot vessel that, when filled with water, carries roughly 125,100 pounds of liquid across its full 101-by-511-inch footprint. Excavation, bedding, and backfill must be engineered to carry that load. Norwesco lists it with a septic tank classification — confirm local approvals before committing. No specific-gravity rating is published; do not store liquids heavier than water without confirmation. And remember: inlet, outlet, manway, and riser layout is the single biggest setup detail on a tank this size. Norwesco 15000 Gallon HDPE Underground Liquid Storage Tank. Built for burial.
