The Norwesco 6502 gallon black heavy-duty vertical storage tank is built for high-volume bulk water service on farms, rural fire-water reservoirs, industrial process sites, and water reuse systems. This Norwesco vertical storage tank stands 196 inches tall on a 102 x 102 inch footprint, holds 6,502 gallons, and the black polyethylene wall limits light transmission into the stored water, which helps slow algae growth in outdoor installs.
Capacity 6,502 gal | Height 196 in | Diameter 102 in | Footprint 102 x 102 in | Specific gravity rating 1.9 | Material Black polyethylene
Will it work for your site?
This is a vertical storage tank molded in polyethylene and rated to a specific gravity of 1.9, which means it is built to carry contents heavier than water without compromising the wall. That 1.9 figure is Norwesco's heavy-duty rating, so for plain water you have margin to spare and no reason to step up. Filled with water alone, the tank carries roughly 54,227 pounds of contents; at its full 1.9 specific gravity rating it is designed to hold up to 103,031 pounds. Those are real numbers to plan around when you size your pad and your fill schedule. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 6,502 gallon capacity matches your draw-down and refill cadence before you commit.
Foundation and freeze planning
At nearly 27 tons full of water on a 102 x 102 inch base, a tank this size lives or dies on its foundation. Spend the time up front on a properly engineered, level pad so the load is carried evenly across the full footprint. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary sits. If this tank is going into rural or remote fire-protection duty, read our fire-water reservoir tank design guide for NFPA 22 sizing discipline and cold-climate freeze-protection engineering. For grey-water, rainwater, or HVAC condensate aggregation, our industrial water reuse tank topology guide covers quality-banded storage trains and stage sequencing.
The mistake to avoid
The common error on a tank this large is treating the bulkhead fittings and plumbing as an afterthought. Outlet, fill, and vent fitting sizes are not yet confirmed in our data for this SKU, so confirm them against the technical drawing on this page or call 866-418-1777 before you order any bulkhead fittings or gaskets. Match the drawing's port locations to your manifold layout while the tank is still empty and easy to position, because moving a fitting on a full 6,502 gallon tank is not an option. The black exterior also means the contents will warm under direct sun, so plan for that if your application is temperature-sensitive.
Freight and ordering
This Norwesco vertical storage tank ships LTL freight from the Albertville, Alabama plant. At 196 inches tall it is an over-dimensional load that exceeds standard trailer-door height for many carriers, so expect flatbed or specialized handling, and expect distance plus that height to drive the cost. Because of that, we quote freight live to your delivery ZIP rather than baking a guess into the price. Get an exact number with our Freight Cost Estimator, or call 866-418-1777 and we will work the freight and lead time with you directly.
