The Norwesco 3000 Gallon Dark Green Vertical Water Storage Tank is built for serious bulk water duty - rural fire reserve, irrigation supply, rainwater collection, and process makeup water. It holds 3,000 gallons in a vertical storage tank that stands 93 inches tall on a 102-inch diameter body, giving you high capacity without sprawling across your site. The dark green polyethylene resists UV and blocks the light penetration that promotes algae, making it a practical outdoor water storage tank for above-ground service.
Will this tank work for your job?
This is a vertical water tank rated at a 1.0 specific gravity, which is exactly what you want for water and water-equivalent contents at room-temperature density. Filled to capacity, 3,000 gallons of water weighs 25,020 pounds, and that figure is also the maximum rated contents weight - so plan your pad, base, and structural support around roughly 25,000 pounds when full. Note the two dimensions: the tank body is 102 inches in diameter, and the pad footprint to support it is 102 x 102 inches square, so you need a level, fully bearing surface under the entire base. For matching capacity to your actual draw and refill rate, run the numbers with our Tank Sizing Calculator and review the Tank Sizing Guide.
Check fittings against the drawing before you plumb it
Confirm inlet, outlet, and any riser fitting sizes and elevations against the technical drawing on this page before you finalize your plumbing layout - the dome and sidewall fitting positions are shown there. Bulkhead fittings and gaskets on a tank this size are configured per order and sized off the drawing, so call us at 866-418-1777 to set up the exact fitting package you need. Do not order risers or connections until you have verified the elevations.
Set it up right - the mistake to avoid
The most common and most expensive error with a tank this large is the foundation. A full 3,000-gallon tank puts more than 25,000 pounds on the ground in a 102-inch square footprint, so it must sit on a flat, continuous, fully bearing surface - not gravel that can wash or settle, and never on bare ground that lets the base flex. If you are pouring concrete, size and reinforce the pad for the loaded weight; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and the ACI 318 boundary. In cold climates, plan freeze protection for the outlet and any exposed plumbing.
The right size for the job
A 3,000-gallon vertical water storage tank hits a sweet spot for rural and remote sites. For private fire protection, see our guide on fire-water reservoir tank design for rural and remote sites, which covers NFPA 22 sizing discipline and freeze protection for cold-climate service. If you are aggregating grey water, rainwater, or HVAC condensate for reuse, our breakdown of industrial water reuse tank topology shows where a tank this size fits in a quality-banded storage train.

This tank ships LTL freight from the Washougal, WA plant, quoted live to your ZIP code. Because it ships from a single Pacific-Northwest plant and goes out as a large-cube, 25,020-pound-when-full item, East Coast buyers should pull a quote early with our Freight Cost Estimator to plan delivery. Listed before freight - or call us at 866-418-1777 and we will walk you through sizing, fittings, and shipping so there are no surprises.
