The Norwesco 3000 Gallon Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for bulk water and high-density liquid duty. It holds 3,000 gallons, stands 109 inches tall on a 95-inch footprint (95.0 x 95.0), and carries a 1.9 specific gravity rating - the heavy-duty wall rating for this build. The black color blocks light to suppress algae growth in stored water, which is why it shows up in searches for a black Norwesco vertical tank for outdoor and exposed installations.
Will this tank work for your job?
Run the numbers before you set it. Filled with water, the tank and its contents weigh about 25,020 lb, and the pad underneath has to carry that load across the full 95-inch footprint. At the tank's maximum rated contents, total weight reaches 47,538 lb - the figure that matters when you store a liquid heavier than water and want to stay inside the 1.9 SG rating. That 1.9 rating is the headroom: it tells you how dense a liquid this wall is engineered to hold, so a fluid up to 1.9 specific gravity stays within design limits. Before you commit to a spot, confirm 109 inches of overhead clearance for the tank's height and a clear access path at least 95 inches wide to get it into place. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 3,000-gallon size and the loaded weight against your site before you pour a pad.
Foundation and site prep
A loaded 3,000-gallon vertical tank is a serious point load, so the pad is not an afterthought. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies, so the foundation matches the full 25,020 lb water weight. If this tank is going into rural fire-protection storage, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites. For grey-water, rainwater, or HVAC condensate reuse, see our breakdown of industrial water reuse tank topology. Refer to the technical drawing on this page for fitting locations and exact dimensions before you plumb the inlet and outlet.
The mistake to avoid
Do not assume the black exterior alone qualifies this tank for a chemical it was not rated for. The 1.9 SG rating defines the maximum liquid density, not chemical compatibility - those are two separate questions. Spec the tank to the actual weight of what you are storing, and if you are moving from water to a denser fluid, recheck the loaded weight against the 47,538 lb maximum rated contents before you fill. Getting the specific gravity right at the order stage avoids the most common and most expensive mistake on a tank this size.
Norwesco molds this tank at 11 plants across the country, so the nearest one - among Burnet, TX; Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Owego, NY; Shawnee, OK; Sheldon, IA; St. Bonifacius, MN; Tooele, UT; and Washougal, WA - is the one that ships to you, cutting LTL distance and cost compared with a single-origin seller. The tank arrives empty on an LTL freight carrier, and delivery is curbside, so confirm your offload and forklift or crane access before the truck shows up. Freight is quoted live to your ZIP: use the Freight Cost Estimator for a delivered freight estimate, or call 866-418-1777 to lock in your order and confirm the closest shipping point.
