The Norwesco 1500 Gallon Multi-Use Underground Liquid Storage Tank (SKU N-41822) is a blue polyethylene Bruiser tank built for buried liquid storage. It holds 1,500 gallons and measures 70" tall, 55" wide, and 135" long, giving you a 55" x 135" footprint to plan your excavation around. Filled with water it carries roughly 12,510 lb, so the bedding, backfill, and burial depth all have to be engineered before this norwesco tank goes in the ground. See the technical drawing on this page for the fitting and dimensional layout.
Does it work for your underground job?
This is an underground tank, not an above-ground vertical, so the support story is different: the surrounding soil and properly compacted bedding carry the load, not a concrete pad. Plan your trench around the 70" deep x 55" wide x 135" long envelope plus the bedding and side clearance the manufacturer's underground install guide calls for. As a multi-use polyethylene storage tank, it is designed for non-pressurized liquid storage. Run the numbers with the Tank Sizing Calculator and Tank Sizing Guide to confirm 1,500 gallons matches your demand before you dig. A buried 1,500-gallon poly tank is also a real candidate for rural fire-water reservoir storage; our fire-water reservoir design guide walks through NFPA 22 sizing if that is your use case.
How it ships
N-41822 ships LTL freight from the Norwesco plant in Hanford, CA, and freight is quoted live to your ZIP code. At 135" long this is an oversized unit, so delivery is curbside by an LTL carrier and you should plan equipment and help to offload it. Because it leaves from a single California plant, far-East ZIPs should expect longer transit and fewer carrier options, so set your delivery timeline accordingly, not just your budget. Get an exact number with the Freight Cost Estimator or call us and we will quote it for you.
The mistake to avoid
The most expensive error on a buried tank this size is anti-flotation. The real risk is an EMPTY tank under a high water table, which wants to float; the 12,510 lb full-water figure is your loaded reference, but you must ballast and anchor against the empty condition, not the full one. Get the bedding, backfill compaction, anti-flotation, and burial-depth details right per the manufacturer's underground installation guidance, because burial is unforgiving once backfilled.
Confirm before you order
This unit has no published specific-gravity rating, and our data carries no fitting or gasket spec for it, so for any liquid heavier than water, or any fitting or gasket compatibility question, confirm it with us or the manufacturer before you order. Never exceed water-equivalent weight without checking. When in doubt on the liquid, call before you buy rather than after you bury.
