The Norwesco 11000 Gallon Black Vertical Storage Tank is built for sites that need serious bulk water capacity in a single footprint - rural fire-water reservoirs, agricultural irrigation, industrial process water, and graywater or rainwater aggregation. This is one of Norwesco's largest vertical polyethylene tanks, holding 11,000 gallons in a black shell that stands 167 inches tall on a 144 x 144 inch footprint, shipping LTL from the plant in Albertville, Alabama with freight quoted live to your ZIP.
Will this tank work for your site?
The specifications drive every decision here. Capacity is 11,000 gallons, height is 167 inches, and the base measures 144 x 144 inches (12 feet square) - plan your pad and clearance around those numbers, not estimates. At 167 inches the tank stands roughly 13.9 feet tall, so verify overhead fill and vent clearance plus gate or doorway access at the set area before you commit. The shell is molded from polyethylene and carries a 1.5 specific gravity rating, meaning it is built to hold contents up to 1.5 times the weight of water. For plain water at full capacity, that is roughly 91,740 pounds of water alone; at the full 1.5 SG rating the contents can reach about 137,610 pounds. That SG headroom is a real capability, not just a rating - this same tank handles denser-than-water solutions up to 1.5x water weight, which matters if you are weighing it against a 1.0 SG water-only tank. The black resin is a functional choice for stored water too: it blocks light to inhibit algae growth. Use our Tank Sizing Calculator and Tank Sizing Guide to confirm this vertical storage tank matches your volume and draw-down needs before you order.
Foundation and freight - the mistakes to avoid
The single most expensive mistake with an 11,000-gallon vertical tank is the pad. Filled with water, this tank carries more than 45 tons of contents on a 12-foot-square base; at the 1.5 SG rating that climbs toward 68 tons. The pad must be flat, fully supporting, and engineered for that load - a tank set on an uneven or undersized foundation will stress and fail regardless of how good the shell is. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework and where the ACI 318 boundary applies. If you are deploying this as a rural or remote fire-water reservoir, our fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. Because this is a freight-dominated buy from a single plant in Alabama, get a freight quote to your ZIP and confirm lead time before you invest in pad engineering.
Confirm fittings and reuse-train fit
Outlet location and bulkhead size are install-critical on a tank this size, and configuration can vary - if a technical drawing is shown on this page, use it for fitting locations and dimensional detail, and call 866-418-1777 to confirm the exact outlet and fitting setup before you order. At 11,000 gallons this tank is sized for bulk storage trains where a single large reservoir consolidates multiple feeds. Our guide on industrial water reuse tank topology covers quality-banded storage trains and treatment-stage sequencing for graywater, rainwater, and HVAC condensate aggregation, and if rainwater harvesting is your application, the first-flush diverter sizing guide follows the Texas Manual on Rainwater Harvesting, 3rd Edition.
