The Norwesco 160 gallon vertical liquid storage tank is a 69-inch-tall white polyethylene vessel on a tight 28 x 28 inch footprint, sold here without fittings so you can plumb the bulkhead, outlet, and lid hardware that match your install rather than work around a pre-drilled port you did not pick. It is the right size when you need real standing water reserve in a small slab area: a feed-water buffer, a rural fire-water reservoir, a rainwater catchment leg, or a remote storage tank for a pump system.
Will this Norwesco vertical tank work for your liquid?
This is a white polyethylene Norwesco vertical tank rated to 1.5 specific gravity, which means the wall is built to hold contents up to 1.5 times the weight of water. For plain water (SG 1.0) that is generous headroom. Filled with water the contents weigh about 1,334 lb, and the wall is rated to carry up to 2,002 lb of contents at the full 1.5 SG rating, so you have margin for heavier-than-water liquids within that limit. If your contents run heavier than water — up to 1.5 SG and 2,002 lb — this tank already covers you, so you do not need to step up to a heavier-wall model; just confirm your liquid's specific gravity stays under that 1.5 number before you fill. The footprint is 28 x 28 inches and the tank stands 69 inches tall, so plan your inlet height, ladder or fill access, and overhead clearance around that 69-inch profile.
Sizing and pad
Because this storage tank carries roughly 1,334 lb of water when full on a 28 x 28 inch footprint — about 5.44 square feet — it puts down close to 245 lb per square foot at full water, and more at 1.5 SG. A vertical tank that tall wants to sit dead level, so pour or verify a flat, fully supporting base before it goes into service. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground poly tanks, and if you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to demand. For rural fire-protection use, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. The complete 160-gallon vertical tank buyer's guide for this exact 28 x 69 model is also linked from this page. You can review the technical drawing on this page for the full dimensional layout.
The mistake to avoid
The buyer ordering this Norwesco tank without fittings needs that to be deliberate. With no hardware included, source three items before the tank ships, or it will sit empty waiting on parts: the bulkhead fitting, the outlet, and the lid hardware — each matched on thread and pipe size and on gasket material for your liquid's chemistry and temperature, not just the pipe thread. Call us at 866-418-1777 to confirm fitting options before you order. The second mistake is treating the 1.5 SG rating as a license to fill with anything: it sets a weight ceiling, not a chemical-compatibility approval, so verify your contents' specific gravity stays under 1.5.
This tank ships LTL freight from the nearest Norwesco plant — Sheldon, IA or Washington Court House, OH. Because Norwesco molds this tank in both Iowa and Ohio, the Freight Estimator routes from whichever is closer to your delivery ZIP, so central and eastern buyers usually see the shorter haul, with the rate quoted live to your ZIP. Get an exact number from our Freight Cost Estimator, or call 866-418-1777 and we will quote it and confirm fitting options before you order.
