The Norwesco N-42042 is a 3000 gallon vertical water storage tank molded in black polyethylene, standing 93 inches tall on a 102-inch diameter footprint. The black resin blocks light to slow algae growth in stored water, and the tank carries a 1.0 specific gravity rating - sized for water and other liquids no heavier than water. Filled to capacity, it holds roughly 25,020 pounds of water, so the pad it sits on has to carry that full load year round.
Does this tank fit your site and water plan?
Plan around two numbers: the 102-inch round footprint and the 25,020-pound full-water weight. That weight is the maximum rated contents weight for this tank, and it lands across the full 102-inch diameter base - roughly 3 pounds per square inch, or about 440 pounds per square foot, on whatever the tank sits on. That is why the base needs to be flat, level, and fully supporting across the entire footprint: a sand bed or a level concrete pad both work, as long as the tank is supported edge to edge with no voids underneath. If you are weighing this 3000-gallon size against a larger or smaller vertical, the Tank Sizing Calculator and the Tank Sizing Guide walk through capacity, footprint, and weight side by side. For the full specification rundown on this exact model, the complete buyer's guide covers it in depth.
What is this vertical water storage tank good for?
This size is a workhorse for rural and remote water supply, bulk water storage, hauled-water holding, and fire-water reservoir duty. If fire protection is the goal, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. For grey-water, rainwater, and condensate aggregation, the industrial water reuse tank topology guide lays out quality-banded storage trains. If you need to read the water level through the wall, the same 3000-gallon 102" x 93" footprint is offered in natural white as the 45246 vertical liquid storage tank - a same-spec alternative when visible level matters more than light blocking. Refer to the technical drawing on this page for fitting placement and overall dimensions before you set your plumbing.
The mistake to avoid
The 1.0 specific gravity rating is the line to watch. This tank is built for water and liquids no heavier than water - do not put a heavier-than-water liquid in it expecting the same service life. If your stored liquid is denser than water, step up to a tank rated to a higher specific gravity. Match the rating to the actual liquid, not just the volume.
This tank ships LTL freight from the Norwesco plant in Fairfield, TX, with freight quoted live to your ZIP. Because LTL cost scales with distance from Fairfield, buyers in or near Texas will typically see materially lower freight than coastal ZIPs - run your ZIP through the Freight Cost Estimator before comparing this tank to a closer-shipping option, or call 866-418-1777 and our team will help you confirm sizing, footprint, and delivery before you order.
