The Norwesco 1500 Gallon Plastic Water Storage Tank (SKU N-41506) is a vertical polyethylene tank standing 60 inches tall on a 93-inch diameter footprint, sized for bulk water storage where you need real volume in a compact, low-profile cylinder. Full of water it carries 12,510 lb, and that single number drives almost every decision you make about this tank - from the slab you pour to the freight that brings it to your site.
Will it work for your site?
This is a 1500-gallon vertical storage tank built from polyethylene with a specific gravity rating of 1.0, meaning it is engineered for water and water-weight liquids - it is not rated for contents heavier than water. At full capacity it holds 12,510 lb across a 93-inch-diameter base, so plan the location around that footprint and load rather than the 60-inch height. The squat profile suits sites with overhead clearance limits, gravity-feed layouts, and applications like bulk water storage, irrigation reserve, and rainwater aggregation. One honest consequence of that short stature: with only 60 inches of tank height, a full tank delivers at most about 5 feet of static head - roughly 2.2 psi at the outlet - so do not size a gravity-feed line expecting tall-tank pressure. To confirm the tank matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation. That 12,510 lb load sits on a 93-inch circle - about 47 square feet of bearing area - which works out to roughly 265 lb per square foot of average bearing pressure. Check that figure against your soil and slab capacity, then pour and size the base using the framework in our Concrete Pad Sizing for Above-Ground Polyethylene Tanks guide. The base must be flat, fully supported, and level: a tank that bridges a soft spot or overhangs an undersized pad will settle and stress the polyethylene wall. Prove the install with the Hydrostatic Test Methodology approach - fill with water, monitor pad settlement, and check every fitting for leaks before the tank goes into service. Fitting configuration (outlet, bulkhead, and manway sizes and locations) is confirmed at order, so call 866-418-1777 to verify the layout matches your plumbing before you buy.
Built for serious water duty
Because it is rated for water at SG 1.0, this Norwesco vertical tank is for water service - if you need to store a liquid denser than water, call 866-418-1777 and we will spec a higher-rated tank instead of pushing this one past its rating. For water designs it fits naturally into larger systems. In remote and rural settings it can serve as part of a fire-water reserve - see our guide on Fire-Water Reservoir Tank Design for Rural and Remote Sites, which covers NFPA 22 sizing discipline and cold-climate freeze protection. If you are capturing and reusing water, the Industrial Water Reuse Tank Topology guide shows how a vertical storage tank like this one anchors grey-water, rainwater, and HVAC condensate aggregation trains.
