The Norwesco 3000 Gallon Black Vertical Storage Tank is a full-size bulk reservoir built for above-ground water storage where you need real volume in a single, stable footprint. It holds 3,000 gallons, stands 119 inches tall, and sits on a 91 x 91 inch round footprint, so plan your pad and overhead clearance around those numbers before ordering. The black polyethylene construction blocks light to suppress algae growth, which makes this Norwesco vertical tank a practical choice for long-term standing water at rural and remote sites.
Will this tank work for your site?
This is a 3,000-gallon vertical storage tank rated to a specific gravity of 1.5, so it carries water (SG 1.0) with substantial headroom. Filled with water, the tank and contents weigh about 25,020 pounds; at its maximum rated contents weight the tank can carry up to 37,530 pounds. Those are the loads your foundation has to support, and because the full water weight alone is over 25,000 pounds across a 91 x 91 inch footprint, the pad matters as much as the tank itself. A flat, level concrete pad that fully supports the entire footprint is the standard approach for a storage tank this size. If you are sizing the slab, our concrete pad sizing guide for above-ground polyethylene tanks walks through the ACI 360R-10 framework, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 3,000 gallons matches your draw and refill cycle. At full fill the water column stands roughly 8 to 10 feet tall, so the bottom outlet sees real static head; size the outlet fitting, valve, and any downstream gasketed connection for that pressure, not just for flow.
Fittings, clearance, and the SG 1.5 headroom
Confirm the inlet, outlet, and vent fitting sizes against the technical drawing on this page before sourcing bulkhead fittings, gaskets, and valves. A 3,000-gallon reservoir at full head needs correctly torqued bulkhead and gasket assemblies at the outlet to avoid weeping at the base, so treat the seal discipline there as part of the install, not an afterthought. Plan clearance above the 119-inch tank height for fill and lid access and for any float or level sensor, and confirm doorway and overhead clearance on the delivery path and at the final pad, since this unit stands nearly 10 feet tall. The SG 1.5 wall rating is worth understanding before you buy: it carries denser liquids than water with margin, which is why the max rated contents weight is 37,530 lb versus 25,020 lb full of water. If your service is heavier than plain water now, or could change later, that rating is structural headroom you are already paying for that lighter SG-1.0-only tanks do not give you.
Common uses and the mistake to avoid
A black 3,000-gallon vertical tank is commonly used for bulk water storage, rainwater and reuse collection, and as a private fire-water reservoir at sites beyond municipal hydrant coverage. If fire protection is your goal, the reservoir has to be sized to the demand, not just to the space you have; our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For greywater, rainwater, and HVAC condensate aggregation, the industrial water reuse topology guide covers quality-banded storage trains, and the rainwater harvesting guide covers first-flush diverter sizing. The mistake to avoid on a tank this large is treating the foundation as an afterthought: an undersized, uneven, or partially supporting pad under more than 25,000 pounds of standing water leads to stress and failure at the base. Build the pad to fully support the entire 91 x 91 inch footprint, level, before the first fill.
This Norwesco vertical tank ships LTL from the Sheldon, Iowa plant, quoted live to your ZIP code. Because of its size and weight, freight is priced per destination rather than baked into the list price, and you are responsible for offload at delivery; for a unit on a 91 x 91 inch footprint standing 119 inches tall, plan equipment or hands to receive it. Get an exact number for your delivery address with the Freight Cost Estimator, or call us at 866-418-1777 and we will quote the tank and freight together and confirm offload requirements for a unit this size.
