The Norwesco 5000 Gallon Black Heavy Duty Vertical Storage Tank is a polyethylene bulk water tank built for large-volume above-ground storage where a high static head and a heavy hydrostatic load come with the job. It stands 152 inches tall on a 102 x 102 inch footprint and is molded in black resin. Rated at 1.9 specific gravity, this is the heavy-duty build: if your stored fluid is denser than water, you already have the structural margin and do not need a separate chemical-grade tank for density alone. That 1.9 SG margin is what makes it a full-column workhorse instead of a tank you have to keep half-empty.
Will it work for your site?
At 5,000 gallons of usable capacity, plan the pad and plumbing around a heavy tank. Full of water this vessel weighs about 41,700 pounds, and the 1.9 SG structural rating carries it to a maximum contents weight of roughly 79,230 pounds. That number drives your foundation: a tank this size belongs on an engineered, level, full-diameter concrete pad sized to the loaded weight, not on bare soil or a partial ring. Plan for a full 102 x 102 inch pad plus working clearance around all sides for fitting access and inspection, and confirm 152 inches of vertical clearance under any roof, eave, or fill point. Our concrete pad sizing guide walks through the ACI framework for above-ground polyethylene tanks of this scale. If you are still confirming volume against draw-down and refill rates, run the numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to the 5000-gallon vertical footprint.
Fittings: confirm against the drawing
See the technical drawing on this page for the fitting layout, overflow, and lid detail to match your inlet and outlet plumbing. Confirm fitting, gasket, and bulkhead sizes against the drawing before ordering mating pipe, valves, or gaskets, and do not assume a standard thread. Support fittings independently so they do not carry pipe loads, and keep the tank plumb once it is set.
Common uses and the mistake to avoid
This is a classic vertical storage tank for bulk water duty: rural and remote fire-water reservoirs, irrigation and ag water, industrial process and reuse water, and rainwater aggregation at volumes a smaller tank cannot hold. If you are designing a private fire-protection reservoir, read our fire-water reservoir design guide for NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate aggregation, our industrial water reuse topology guide and the rainwater harvesting first-flush guide cover the upstream details. The mistake to avoid: underbuilding the foundation. The 1.9 SG rating tells you the resin and wall thickness can carry a dense, full column, but that load has to land on a pad that can take nearly 80,000 pounds. Size the foundation to the loaded weight and keep the tank plumb.
Freight
This tank ships LTL by motor freight, quoted live to your ZIP code. Norwesco molds the 5000-gallon vertical at plants in Fairfield, TX; Griffin, GA; Hanford, CA; Lancaster, OH; Merced, CA; Owego, NY; Shawnee, OK; St. Bonifacius, MN; Tooele, UT; and Washougal, WA, so your tank ships from the plant nearest your ZIP to keep transit short and freight down. Because it molds at 10 plants nationwide, your freight quote depends on which plant is closest to you, so run your ZIP through the Freight Cost Estimator before comparing our price to a competitor since a closer plant can change freight cost more than list price does. A tank this size requires equipment offload: confirm forklift or crane access and a clear, level set-down before delivery, because LTL does not include placement. For help, call us at 866-418-1777 and we will quote the nearest plant for your delivery address and confirm offload requirements.
