The Norwesco 3000 gallon vertical water storage tank is a California-only green polyethylene tank built for bulk water storage where a tall, compact footprint matters. It stands 93 inches high on a 102-inch-diameter base (102 by 102 inches), so it holds 3,000 gallons of stored water inside roughly an 8.5-foot-square pad area. The tank is molded and shipped from California (Hanford or Merced), which is why the green color is offered in California specifically. Confirm this is the version you want for your location before ordering.
Will it work for your site?
This is a vertical water tank molded from polyethylene with a specific gravity rating of 1.0, which means it is sized and rated for water and water-weight contents up to 1.0 SG. Filled to capacity, the full filled load is rated at 25,020 pounds, and that 25,020-pound figure is also the maximum rated contents weight for the tank. Plan your foundation around that number, not the empty weight. Because the load is concentrated on a 102.0 x 102.0 inch footprint, the pad has to carry the full filled weight without settling or flexing. If you are working out pad thickness and reinforcement, the concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. To confirm this capacity fits your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator or the Tank Sizing Guide. No fitting, lid, or outlet data is listed in the catalog for this tank, so read the exact fitting, gasket, lid, and outlet sizes and locations off the technical drawing on this page before ordering any accessories.
Common applications and sizing
At 3,000 gallons this vertical storage tank suits rural water storage, hauled-water reservoirs, irrigation supply, and use as a stored-water buffer in larger systems. For rural fire-protection reservoirs where NFPA 22 sizing and freeze handling come into play, the fire-water reservoir design guide covers how a polyethylene tank fits into a private fire-protection stack. If you are aggregating grey water, rainwater, or HVAC condensate into quality-banded storage trains, the industrial water reuse topology guide covers treatment-stage sequencing for reuse-capable bulk storage. For a full walkthrough of this exact tank, the 3000 gallon green water tank buyer's guide covers the dimensions and setup in detail (the "102 x 93" in its title is the 102-inch diameter by 93-inch height).
The mistake to avoid
The most common error on a tank this size is under-building the foundation. A full 25,020-pound load on a 102 x 102 inch base puts real pressure on the pad, and a soft or uneven base will let the tank lean over time. Pour and cure a level, properly reinforced pad before you ever fill it. Second, confirm the 1.0 specific gravity rating matches your contents: this tank is rated for water at 1.0 SG, so it is built for water storage, not for heavier-than-water liquids. If your stored liquid is denser than water, you need a tank rated for a higher specific gravity.
Freight
This tank ships LTL freight from the nearest Norwesco plant to you, either Hanford, CA or Merced, CA, quoted live to your ZIP code. A 3,000 gallon tank is an oversized freight item, so freight is quoted separately from the tank list price.
