The Norwesco 5000 Gallon Green Vertical Water Storage Tank is a California-only model, molded in polyethylene and produced at the Norwesco plant in Hanford, CA. It holds 5,000 gallons of bulk water on a single footprint, standing 112 inches tall on a 119 x 119 inch base, and is rated to a 1.0 specific gravity, meaning it is engineered for water and water-weight contents. Because it is the green-tinted California-market version shipping from Hanford, buyers outside California should plan the freight conversation early. Whether you are spec'ing a rural fire reserve, irrigation supply, or a treated-water holding train, here is what you need to confirm before it ships.
Will it work for your site?
At full capacity this vertical storage tank carries 41,700 pounds of water, which is also its maximum rated contents weight at a 1.0 specific gravity. That figure drives every upstream decision: the pad, the anchoring, and the geometry of the space you have. The 119 x 119 inch footprint puts roughly 21 tons over about 98 square feet, so check the 112-inch height against your overhead clearance and confirm your pad layout before you commit. Because the tank is rated to a 1.0 specific gravity, it is matched to water and water-weight liquids, not to denser solutions. To make the 5,000-gallon volume actually map to your draw-down and refill demand, run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide.
Pad and install discipline
A water storage tank carrying nearly 21 tons at full fill puts real bearing load on whatever it stands on. Pour and cure a level, properly sized pad before the first fill — our walkthrough on concrete pad sizing for above-ground polyethylene tanks covers the ACI framework and where the engineered-foundation boundary sits. Once the tank is set, accept it the right way: our hydrostatic test methodology guide lays out the fill discipline, pad-settlement monitoring, and hold-time math that catch problems before the tank is in service. If this volume feeds a private fire-protection stack, our fire-water reservoir design guide ties polyethylene storage into NFPA 22 sizing and cold-climate freeze protection. For reuse builds, the water reuse topology guide shows where a tank this size fits in a quality-banded storage train.
The mistake to avoid
The 1.0 specific gravity rating is the line you do not cross. A 1.0 rating means the tank is validated for water-density contents; pushing a denser liquid past that rating asks it to carry more than it was designed for. Confirm your contents stay at or under 1.0 specific gravity. If you need to store a heavier-than-water solution, call 866-418-1777 and ask about a higher-SG-rated tank before you order. We also do not have the published fitting schedule for this model, so confirm inlet, outlet, and manway sizes and locations with us by phone before you order — fitting layout is set at the factory. You can also reference the technical drawing on this page for overall geometry.
