The Norwesco 105 Gallon Black Vertical Storage Tank is a compact upright polyethylene tank that holds 105 gallons in a tight 23-inch by 23-inch footprint while standing 63 inches tall. That narrow footprint is the point: a 23-inch base clears a standard doorway and fits tight equipment pads, mechanical closets, and trailer corners where a sprawling tank will not. The black, light-blocking polyethylene wall suppresses algae growth, making this Norwesco vertical tank a practical choice for outdoor water storage, rural fire-water reserves, rainwater capture, and general bulk liquid holding where floor space is at a premium.
Will this Norwesco vertical tank work for your application?
This is a vertical storage tank rated to a specific gravity of 1.5, so the polyethylene wall is built to carry liquids up to 1.5 times the weight of water. Filled with plain water (8.34 lb/gal), the tank holds roughly 876 pounds of contents; at its full 1.5 SG rating it can carry up to 1,314 pounds of liquid weight. The top is configured for a 60002 lid, which is the primary access and fill point. If 105 gallons is in the range you are considering but you are not certain it matches your draw rate or storage cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Siting, pad, and freeze considerations
A full tank exerts meaningful point loads, so set it on a level, fully supporting surface and size the pad to the 1,314-pound maximum rather than the 876-pound water figure. In cold climates that margin matters even more: contents freezing adds expansion load on top of the standing weight, so build the foundation and stand for the worst case. For a permanent above-ground install, size the foundation using our guide to concrete pad sizing for above-ground polyethylene tanks. If this tank is part of a private fire-protection setup, the fire-water reservoir design guide walks through reserve sizing and freeze-protection engineering. If you are aggregating rainwater, grey water, or condensate, the water reuse tank topology guide shows how a tank this size fits into a banded storage train. See the technical drawing on this page for exact fitting and lid placement.
The one thing to get right
The most common mistake on a narrow vertical tank like this is treating the 1.5 specific gravity rating as a green light for any liquid. The SG rating tells you the wall can carry the weight of a denser-than-water liquid up to 1.5 SG; it says nothing about whether the polyethylene resin is chemically compatible with what you intend to store. This is a water-service tank in our catalog. Before you fill it with anything other than plain water, work a short checklist: (a) confirm the contents weight stays at or under the 1,314-pound maximum, (b) confirm the 60002 lid seals adequately for your liquid and any vapor, and (c) call us to confirm chemical fit. When in doubt, call before you fill.
