The 1525 Gallon Plastic Water Storage Tank from Norwesco is a vertical polyethylene tank standing 62 inches tall on a 93-inch diameter footprint, built for bulk water storage where a wide, stable base matters more than vertical clearance. At 1,525 gallons it holds enough for rural fire reserve, irrigation supply, hauled-water buffering, or process makeup water without stacking into a tall, top-heavy profile. The squat geometry keeps the center of gravity low and spreads the load across a broad base, which simplifies pad design and keeps this Norwesco vertical storage tank stable when full.
Will it work for your site?
This is a vertical water storage tank rated for a specific gravity of 1.0, meaning it is engineered for water and water-density liquids. Filled to capacity, the contents weigh 12,718 pounds — and that loaded figure is also the maximum rated contents weight for the tank, so the pad-design number and the structural ceiling are the same glance:
Loaded weight: 12,718 lb — also the tank's maximum rated contents weight.
Plan your foundation around the loaded number, not the empty shell: a 93-inch-diameter footprint carrying roughly 12,700 pounds of water needs a properly sized, level, fully supporting pad. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm this 1525-gallon size against your draw rate and refill cycle before you commit. For the concrete underneath it, see our guide on concrete pad sizing for above-ground polyethylene tanks, which works through the ACI 360R-10 framework for a load of this magnitude.
Fittings, dimensions, and what to verify before install
Confirm the fill, lid, and outlet configuration on this specific tank against the technical drawing on this page before you plumb it — or call 866-418-1777 and we will confirm the fitting sizes and positions before you order, so you can size your inlet and discharge plumbing correctly. Verify the 62-inch height clears any roof, eave, or overhead obstruction at your fill point, and check where the top fill opening sits relative to the line you intend to run. The most common mistake on a tank this size is treating the SG 1.0 rating as a suggestion: it is the structural limit. Water and dilute, water-density solutions are fine; anything you would describe as a brine, concentrate, or chemical is heavier than water, overloads the wall, and voids the rating — that service needs a tank rated above 1.0, quoted separately by phone. If you are bringing a new tank online, follow a disciplined fill on first use rather than slamming it full, and watch the pad as it loads — the approach in our hydrostatic test methodology for new-install acceptance, which covers water-fill discipline, pad-settlement monitoring, and fitting leak detection.
Common applications
As a Norwesco vertical storage tank, this size fits private fire-protection reserves, where the role of polyethylene bulk storage is covered in our fire-water reservoir tank design guide, as well as collected grey-water, rainwater, and HVAC condensate aggregation detailed in our industrial water reuse tank topology guide.
This tank ships LTL freight from the Norwesco plant in Fairfield, Texas, with freight quoted live to your ZIP — if you are anywhere in Texas or the South-Central region, that nearby origin often works in your favor on a 12,718-pound shipment.
