The Norwesco 1505 Gallon Black Heavy Duty Vertical Storage Tank is a polyethylene vertical tank built for serious bulk water and liquid storage, standing 135 inches tall on a 60 by 60 inch footprint - roughly 60 inches in diameter and 11.25 feet to the top. The black resin shades stored contents to suppress algae growth, and the 1.9 specific gravity rating gives you real headroom above plain water: this Norwesco vertical storage tank is engineered to hold liquids heavier than water without compromising the tank wall. Before you commit, size it with our tools, then get freight quoted to your ZIP - the Tank Sizing Calculator and Freight Cost Estimator cover both ends of that decision.
Will it work for your site?
Capacity is 1505 gallons of usable storage. Filled with water, the contents alone weigh 12,552 pounds, and at the tank's full 1.9 SG rating the maximum rated contents weight climbs to 23,848 pounds. That maximum is the number that matters for your pad: a slab carrying nearly 12 tons of liquid over a 60 by 60 inch footprint concentrates significant load, so size the foundation before the tank arrives. Our concrete pad sizing guide for above-ground polyethylene tanks walks through the ACI 360R-10 framework for a level, full-bearing base. If you are still settling on capacity, the Tank Sizing Guide helps you match volume to demand. The 135-inch overall height also affects receiving: it is a tall LTL piece, so confirm your forklift or boom can offload at that height and that the delivery site clears it. See the technical drawing on this page for the inlet, outlet, and lid layout.
Common applications
At 1505 gallons in a tall vertical format, this tank suits rural and remote fire-water reservoirs, harvested-rainwater and reuse storage, and general industrial bulk liquid storage where vertical footprint efficiency matters. For fire-protection service, our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection. If you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse tank topology guide covers quality-banded storage trains, and our rainwater harvesting guide details first-flush diverter sizing.
The mistake to avoid
The most common error on a tank this size is underbuilding the foundation. Plan around the 23,848 pound maximum rated contents weight, not the empty tank weight - a pad sized only for the shell will crack or settle once the tank is filled with a high-SG liquid. If your liquid exceeds 1.0 SG (water), this 1.9-rated heavy-duty wall is the spec to confirm against your contents' density: that rating is the ceiling for liquid weight this tank is built to carry. Because the fitting configuration is not specified online, call 866-418-1777 to confirm inlet, outlet, lid, and gasket details against your plumbing before you order.
