The Norwesco 3000 Gallon Green Vertical Water Storage Tank is a California-only model built for above-ground bulk water storage, holding a full 3,000 gallons in a polyethylene tank rated to 1.0 specific gravity. It stands 95 inches in diameter by 109 inches tall, packing serious volume onto a compact 95 x 95-inch footprint. That makes it a workhorse for ranch, agricultural, rural fire-protection, and industrial water-supply work across California, and the green color is the California-only configuration for this Norwesco vertical storage tank.
Will this tank work for your site?
The numbers that matter for planning: this vertical tank is 95 inches in diameter and 109 inches tall, so it stands a hair over 9 feet. A standard 8-foot doorway or garage opening will not pass it upright, and you will need clearance above the 109-inch dome for fill, gauge, and inspection access, so confirm both your overhead room and the gate or path the tank has to travel before it reaches its pad. Filled to its rated 3,000 gallons, the tank and water together weigh 25,020 pounds, which is also its maximum rated contents weight. That load is the single most important figure for your foundation. A tank this heavy needs a properly engineered, level concrete pad sized for the full water weight, not bare soil or gravel that can settle and stress the tank wall. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks.
Sizing it right and storing the right contents
The 1.0 specific gravity rating is a hard guardrail: this is a water storage tank, and at SG 1.0 the rated weight ceiling is already reached with plain water. Do not store anything denser than water in it. If you are still deciding between 3,000 gallons and a larger or smaller capacity, run your demand through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit. For rural and remote fire-protection storage, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection, and if you are aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse topology guide maps out quality-banded storage trains.

The mistake to avoid
The most common and most expensive error with a tank this size is underbuilding the foundation. At 25,020 pounds full, this tank will find every soft spot, slope, and void beneath it. Empty, the shell is light enough for a few people or light equipment to position, but once water goes in it must never be moved or supported only partway. Set it on a flat, structurally sound, level pad before you add a drop of water, and never partially support the base. Check the fitting layout against the technical drawing on this page so your inlet, outlet, and overflow line up with your plumbing before delivery.
Because this is the California-only green configuration, freight is a real advantage: it ships in-state by LTL from the Norwesco plant in Hanford, CA, a short lane for most California addresses, quoted live to your ZIP code.
