The Norwesco 1000 gallon dark green vertical water storage tank holds a full 1,000 gallons in a polyethylene body that stands 80 inches tall on a 64 by 64 inch footprint. The dark green resin is built for outdoor water service: it cuts light penetration to slow algae growth and blends into a yard, treeline, or jobsite better than a white or black tank. This is a straightforward, large-volume vertical storage tank for rural homes, livestock, irrigation, rainwater capture, and bulk water hauling.
Will it work for your site?
Plan around the real numbers, not a guess. Full of plain water at a specific gravity of 1.0, the contents weigh 8,340 pounds — the maximum rated contents weight for this tank. That load sits on a 64.0 x 64.0 inch base, which works out to roughly 2 psi (about 293 pounds per square foot) of bearing pressure spread across the square, a figure you can hand to whoever pours the pad. The tank stands 80 inches tall, so confirm overhead clearance for filling and for the lid before you set it. If you are still choosing a size, run your draw and refill cycle through our Tank Sizing Calculator and read the Tank Sizing Guide to match gallons to demand.
Foundation and freeze planning
A vertical storage tank carrying four tons of water needs a level, fully supporting base. A flat, properly sized concrete pad is the standard approach for above-ground polyethylene tanks of this weight; our guide on concrete pad sizing within the ACI 360R-10 framework walks through how to spec it using the bearing numbers above. In cold-climate service, plan freeze protection before the first hard winter. If this tank is part of a rural fire-protection reserve, our write-up on fire-water reservoir tank design and NFPA 22 sizing discipline covers reserve sizing and cold-weather engineering. Operators building grey-water, rainwater, or HVAC-condensate trains will find the industrial water reuse tank topology guide useful — and this is where the dark green color earns its keep, since stored non-chlorinated water is exactly where algae control matters most.
The mistake to avoid
This tank is rated to a specific gravity of 1.0, which covers water and water-like liquids only. Do not put a heavier-than-water liquid in it expecting the same service life; a higher specific gravity load stresses the wall beyond what this 1.0-rated tank is built for, and a heavier liquid calls for a higher-SG-rated tank instead. Fitting and outlet locations are shown on the technical drawing on this page, so check it for outlet placement before you plumb the tank in.
Freight is the real cost on a four-ton tank, so it pays to ship from close. This Norwesco vertical water tank is stocked across five regions — Fairfield, TX; Griffin, GA; Shawnee, OK; Tooele, UT; and Washougal, WA — and we ship from the plant nearest you to keep LTL freight down, quoted live to your ZIP.
