The Norwesco 6100 Gallon Black Heavy Duty Vertical Storage Tank is a large-format bulk water tank molded in black polyethylene, standing 140 inches tall on a 119 x 119 inch footprint. Its 1.9 specific gravity rating is what earns the heavy-duty name: the wall is built to hold contents far denser than water. For straight water storage that rating is headroom you will never use up, and on a long-service reservoir that is exactly what you want.

Will this tank work for your site?
Filled with water this tank carries roughly 50,874 pounds of contents, and that single number drives every decision around it. The 119 x 119 inch footprint has to land on a foundation rated for that mass plus the tank itself, fully supported and dead level across the entire base, not just at the edges. At 140 inches tall and a hair under 10 feet wide, plan your access, clearances, and any overhead fill or vent routing before delivery day. Because the shell is rated to 1.9 specific gravity, the structure is cleared for a maximum rated contents weight of about 96,661 pounds, so heavier-than-water fluids are within the design envelope even though this listing is set up as a vertical storage tank for water service. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 6,100 gallons matches your draw and refill cycle before you commit. See the technical drawing on this page for overall geometry.
Fittings
This listing does not specify port, manway, or outlet sizes, so do not size your plumbing off this page. Fitting configuration on a Norwesco vertical tank this size is confirmed at quote, where we lock down the exact outlet, fill, and vent arrangement for your install. Call 866-418-1777 with your connection requirements and we will confirm what is available before you order.
How it ships
A vertical storage tank this size moves by LTL freight, quoted live to your ZIP. Norwesco molds at four plants, so we ship from the one nearest you:
- Griffin, GA
- Owego, NY
- Washington Court House, OH
- Washougal, WA
Pulling from the closest plant is how you keep the freight leg on a 6,100-gallon Norwesco tank short. Get your number with the Freight Cost Estimator or call 866-418-1777 and we will route it from the right location.
The mistake to avoid
The error that sinks installs at this size is the pad. People size the slab for the tank's empty weight or for water alone and forget the combined load path. Set this on a foundation engineered for the full water weight of roughly 50,874 pounds, continuously supported, and dead level. An out-of-level or undersized base under a tank holding 25 tons of water is where stress cracking and failure start. If you are pouring new, walk through concrete pad sizing for above-ground polyethylene tanks first. At 6,100 gallons this tank is a natural fit for a fire-water reservoir or an industrial water-reuse train, and both applications live or die on the foundation and fill discipline; the fire-water reservoir design guide and the industrial water-reuse topology guide cover the rest.
