The Norwesco 600 Gallon Mocha Vertical Water Storage Tank is a 600-gallon polyethylene vertical tank for above-ground water storage, sized at 64 inches in diameter and 50 inches tall on a 64.0 x 64.0 inch footprint. The opaque mocha wall blocks sunlight, the energy source algae need, and blends the tank into a yard, pad, or treeline. If you have been searching for a Norwesco water storage tank or a vertical storage tank that holds a real working reserve without towering over the site, this is the squat, wide-base profile that does it.
Will it work for your site?
This tank is rated for water at a specific gravity of 1.0, which is exactly what you need for rainwater capture, fire-water reserve, irrigation, and general bulk water storage. Filled to 600 gallons, the water alone weighs 5,004 pounds, and the maximum rated contents weight is the same 5,004 pounds, so the tank is built around water-density service rather than heavier liquids. The tank ships empty and is light enough to position before you fill it, but once filled it becomes a fixed 5,004-pound load, so use that full-water number, not the empty weight, when you plan the pad and the inlet plumbing. The wide 64-inch base and 50-inch height give it a low center of gravity, which is part of why this footprint is popular for tight equipment yards and low-clearance spots. For help matching capacity to your draw rate and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a size.
Pad, install, and the mistake to avoid
The most common mistake with a tank this wide is under-building the base. A vertical poly tank needs continuous, level, full-diameter support under the entire 64 x 64 inch footprint, and that 64 x 64 is the diameter at the widest point, so pour the slab to the full 64 inches rather than to a nominal guess. More than 5,000 pounds of water concentrated on roughly a 5-foot circle will find any soft spot, settle, and stress the tank wall. A ring or a few blocks will not do it. Size the slab using the framework in our concrete pad sizing guide (ACI 360R-10 framework), and after install, fill and acceptance-test the tank using the steps in our hydrostatic test methodology so you catch any settlement or fitting leak on first fill rather than months later. See the technical drawing on this page to confirm fitting locations and overall dimensions against your plumbing layout.
Where it fits in your water system
At 600 gallons, this is a right-sized reserve for a single-home rainwater system, a remote fire-water cache, or a buffer tank in a reuse train. If you are designing for rural fire protection, our guide on fire-water reservoir tank design (NFPA 22 sizing) covers how a tank like this fits the private fire-protection stack and how to handle freeze protection in cold climates. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse tank topology guide shows where vertical storage like this belongs in a quality-banded train.
