The Norwesco 1100 Gallon Vertical Water Storage Tank is the California-only green model, fulfilled from the Norwesco plant in Hanford, CA. Built in polyethylene and rated for a specific gravity of 1.0, it is engineered for water and water-density liquids. At 87 inches in diameter and 53 inches tall, it holds 1,100 gallons in a low, stable vertical profile that fits where a taller tank will not. If you are sizing a storage tank, vertical tank, or water storage tank for a property in California, this is the workhorse footprint many sites land on. Because this SKU ships from a single California origin, it is set up for California deliveries — out-of-state buyers should confirm availability and run a freight estimate before ordering.
Will it work for your site?
Capacity is 1,100 gallons in a vertical water tank with an 87-inch diameter base and an overall height of 53 inches, giving an 87.0 x 87.0 inch footprint you can lay out on your pad before the truck arrives. The green coloring is specific to the California-only build. Fitting configuration — inlet, outlet, and lid — is not specified in this listing, so call 866-418-1777 to confirm what this tank comes with before you order. See the technical drawing on this page for dimensional detail, and use our Tank Sizing Calculator and Tank Sizing Guide to confirm this size matches your draw and refill cycle.
The pad is where most installs go wrong
The most common mistake on a tank this size is under-building the foundation. Filled to capacity with water, this tank carries roughly 9,174 pounds of contents — and because the SG rating is 1.0, that full-water weight equals the maximum rated contents weight. There is no heavier-fluid headroom on this SKU: it is a water tank, rated SG 1.0, so do not plan to put a denser liquid in it. A vertical poly tank needs a flat, fully supported, level base, because the entire footprint bears load, not just the rim. With more than 9,000 pounds sitting on an 87-inch circle, an inadequate or settling pad will stress the tank wall over time. Our guide on Concrete Pad Sizing for Above-Ground Polyethylene Tanks walks the ACI 360R-10 framework for getting that slab right, and once it is installed, our Hydrostatic Test Methodology guide covers the water-fill acceptance test that proves the install before you rely on the tank.
Built for water storage and reuse
With its 1.0 specific gravity rating, this tank is matched to water service — irrigation, hauled-water storage, and reuse trains. If you are aggregating grey-water, rainwater, or HVAC condensate, our piece on Industrial Water Reuse Tank Topology shows where a vertical storage tank this size fits in a quality-banded storage train. For rural fire-protection reservoirs, our Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing discipline and freeze protection.
This tank ships LTL freight from the Norwesco plant in Hanford, CA — the single ship point for this California-only SKU — with freight quoted live to your ZIP. Because everything moves from one origin, delivered freight scales hard with distance, so run your ZIP through our Freight Cost Estimator before committing, or call 866-418-1777 and we will quote it for you and help confirm this is the right tank for your site.
