The Norwesco 1525 Gallon Dark Green Vertical Water Storage Tank is a 1,525-gallon polyethylene vertical tank built for bulk water storage on a compact footprint. It stands 62 inches tall on a 93 x 93 inch base, so it holds substantial volume without sprawling across your pad. At 93 inches across and only 62 inches tall, this is a wide-bodied vertical, not the tall-narrow profile most people picture, which has real consequences for how you site it. The dark green color cuts light penetration to slow algae growth in outdoor water service, and the tank carries a 1.0 specific gravity rating, which means it is engineered for water and water-weight liquids only.
Will it work for your site?
This is a vertical water storage tank sized at 1,525 gallons nominal. Filled to capacity with water it carries 12,718 pounds of contents, and that figure is also its maximum rated contents weight at the 1.0 specific gravity rating. Plan your foundation around that number: a fully loaded tank concentrates real weight on its 93 x 93 inch footprint, and the pad has to carry it flat and level. Because it is 93 inches across, verify gate width and pad clearance, not just overhead height, before delivery day. If you are matching tank size to demand, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. For a rural fire-protection reservoir, our fire-water reservoir design guide walks through NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse topology guide covers quality-banded storage trains.
Foundation, fittings, and installation
A vertical tank this size lives or dies on its pad. Fitting sizes and placement are shown on the technical drawing on this page; confirm the inlet, outlet, and lid configuration against your plumbing before you order, or call 866-418-1777 and we will walk it through with you. Our concrete pad sizing guide lays out the ACI 360R-10 framework for above-ground polyethylene tanks, and once the tank is set, the hydrostatic test methodology guide covers the water-fill acceptance procedure: pad settlement monitoring, fitting leak detection, and hold-time math.
The mistake to avoid
The 1.0 specific gravity rating is the line you do not cross. This tank is rated to 12,718 pounds of contents at a 1.0 specific gravity, which is water and water-weight liquids. A contents density above 1.0 pushes the wall past what it is rated to carry, so do not put a heavier-than-water liquid into service expecting the same wall life. This is also a water-class tank, with no chemical-resistance or gasket data provided, so do not assume chemical service. If your application is water storage, this Norwesco vertical is the right tool. If your contents exceed 1.0 specific gravity, this is the wrong tank, call 866-418-1777 and we will match you to a tank rated for your liquid's density. Confirm your liquid's specific gravity against the 1.0 rating before you fill.
