The Norwesco 1500 Gallon Multi-Use Underground Liquid Storage Tank (SKU N-41772) is a blue polyethylene Bruiser Tank built for below-grade liquid storage where above-ground space, freeze exposure, or sightlines rule out a vertical. At 1,500 gallons it measures 135 inches long, 55 inches wide, and 70 inches high, giving you a 55.0 x 135.0-inch footprint to plan your excavation around. It is molded at seven Norwesco plants nationwide, so it ships from the location nearest your ZIP. If you are still deciding between underground capacities or comparing this Norwesco tank to a vertical, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide to confirm 1,500 gallons is the right volume before you commit to a 55 x 135-inch excavation.
Will it work for your job
This is a Norwesco underground tank designed to be buried and backfilled, which is why the body is engineered differently from an above-ground vertical. Empty, the tank is light enough to set with equipment; once filled with water it carries 12,510 pounds, which is exactly why the bedding and backfill around it do real structural work after it is in the ground. Plan your excavation, bedding, and backfill the way the application demands rather than treating it as a simple drop-in. Review the technical drawing on this page for the port and fitting layout, dome geometry, and dimensional detail before you finalize the dig.
The mistake to avoid
The single biggest error with an underground storage tank is treating it like an above-ground one. Backfill support, burial depth, and ballast against flotation when groundwater is present are all part of a correct install, and the bury detail on the technical drawing is there for a reason. Watch your venting, too: a buried tank cycling through fill and draw needs adequate atmospheric venting, and the API 2000 atmospheric vent-capacity guide works through inbreathing, outbreathing, and combined sizing for tanks in this exact 1,500 to 10,000 gallon range. Note as well that the specific-gravity rating on this Bruiser is listed as "No," meaning it is set up for water and water-like liquids rather than heavier chemical service; if you are storing anything denser than water, confirm the correct tank before ordering or call us. For pad and bearing questions, the concrete pad sizing guide walks through the load framework, and if this is feeding a rural fire reservoir, the NFPA 22 reservoir design guide covers sizing discipline and cold-climate protection.
Freight
This tank ships LTL freight, quoted live to your ZIP code. Norwesco molds across several plants, so this storage tank can ship from the location nearest you - Griffin, GA; Lancaster, OH; Owego, NY; Shawnee, OK; St. Bonifacius, MN; Tooele, UT; or Washougal, WA - which keeps the freight leg as short as possible. Get an exact number with the Freight Cost Estimator, or call us at 866-418-1777 and we will confirm the nearest stocking plant, lead time, and delivery details for your site.
