The Norwesco 6100 Gallon Vertical Liquid Storage Tank is a tall polyethylene vertical tank built for high-volume above-ground water and liquid storage. It stands 140 inches tall on a 119-inch diameter footprint and carries a 1.9 specific gravity rating - the spec that tells you it is engineered for heavier-than-water contents, not just plain water. At 6,100 gallons of usable capacity, this is one of the larger vertical storage tanks Norwesco produces and a common choice for rural fire-water reservoirs, agricultural water supply, industrial process water, and bulk water reuse.
Specs at a glance
Height: 140 in. Diameter: 119 in. Footprint: 119-inch-diameter circle. Capacity: 6,100 gallons. Material: polyethylene. Specific gravity rating: 1.9. Use the height and diameter to check overhead clearance, gate width, and crane or forklift access before delivery day - an empty tank of this envelope still needs room to be set and offloaded, and our team will walk through offload on the freight call.
Will it work for your site?
Plan around two weights. Filled with water, this tank carries roughly 50,874 lb of water alone; against its 1.9 specific gravity rating, the maximum rated contents weight is about 96,661 lb. That second number is what drives your pad design, not the empty tank weight. A 6,100-gallon vertical tank concentrates that load over a 119-inch diameter circle, so a properly engineered, level concrete pad is not optional. Walk through our concrete pad sizing guide before you pour, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm this Norwesco vertical tank matches your throughput and standpipe needs.
The mistake to avoid
The 1.9 specific gravity rating is a ceiling, not a free pass. It means the tank wall is built to hold liquids up to 1.9 times the weight of water at full volume, which makes this the right tier for heavier-than-water contents rather than over-spec'd - if you are storing a denser liquid, this 1.9-rated model is the correct pick over a standard water-only vertical tank. You still have to confirm your actual contents fall at or below that figure, and that your fittings and outlet placement suit how you fill and draw down. Because the structured fitting data for this tank is best confirmed visually, review the technical drawing on this page for fitting sizes and locations as a pre-purchase step. For fire-protection or any regulated service, verify the specific tank model against the requirement that governs your install rather than assuming a vertical storage tank covers it. If this tank feeds a private fire-protection system, our fire-water reservoir design guide walks through NFPA 22 sizing and cold-climate freeze protection.

Reuse and process water
If you are aggregating grey water, rainwater, or HVAC condensate into a banded storage train, a tank this size anchors the bulk-storage stage of a reuse system. Our guide on industrial water reuse tank topology covers how to sequence treatment stages around storage of this scale.
This tank ships LTL freight. It is produced at multiple Norwesco plants - Griffin, GA; Lancaster, OH; Owego, NY; and Washougal, WA - and ships from the location nearest you, so a Southeast, Midwest, Northeast, or West Coast buyer usually has a close origin.
