The 15000 Gallon Vertical Liquid Storage Tank from Norwesco is a polyethylene vertical storage tank built for high-volume bulk water service, holding 15,000 gallons in a single upright cylinder. At 186 inches tall on a 165-inch diameter footprint, it stages a serious volume of water on a compact circular pad, which is why it shows up in fire-water reservoir, water reuse, and rural bulk-supply specs. The tank carries a 1.5 specific gravity rating, which is a structural weight rating: plain water at SG 1.0 loads it to about 125,100 pounds against that 187,650-pound, 1.5-SG ceiling, so you have substantial headroom for denser water-based solutions up to 1.5 specific gravity. This is a water-class product; for any non-water fluid, confirm chemical compatibility before use.
Will it hold your water
Capacity is 15,000 gallons in a vertical polyethylene tank measuring 186 inches in height by 165 inches in diameter. The numbers that matter for your foundation are the loaded weights: full of water this tank carries roughly 125,100 pounds, and at its maximum rated 1.5 specific gravity contents it reaches about 187,650 pounds. Size your pad to the loaded weight, not the dry weight. Plan for the full 165 in (13 ft 9 in) diameter plus working clearance, and 186 in (15 ft 6 in) of vertical set height under any roof, crane hook, or fill structure. Because the footprint is a 165-inch-diameter circle, a tank this size belongs on an engineered concrete pad. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 15,000 gallons is the right volume before you commit.
Where it ships from and how freight works
This is a large vertical tank that moves by LTL freight, quoted live to your ZIP. Norwesco molds this size across several plants, and we route from the nearest of these four to keep freight down: Albertville, AL; Fairfield, TX; St. Bonifacius, MN; and Washington Court House, OH. Because not every plant necessarily molds every size, confirm the actual molding origin for this tank at quote time. A tank with a 165-inch diameter and a loaded weight in the six figures is a dedicated, often crane-set delivery, so getting the closest origin and an accurate destination ZIP into the quote matters. Use the Freight Cost Estimator for a live freight number to your site, or call 866-418-1777 to talk through plant origin, access, and offload before you order.
The mistake to avoid
The common error on a tank this large is sizing the foundation and the rigging to the empty tank or to plain water weight. Plan for the full 187,650-pound rated load, confirm your pad and soil-bearing can carry it, and verify offload equipment can handle the diameter and set height. For high-stakes applications such as a private fire-water reservoir, the volume you actually need is driven by your duration and flow requirements, not by the tank that fits the pad you already have. Our guide on fire-water reservoir tank design for rural and remote sites covers NFPA 22 sizing discipline and cold-climate freeze protection, and our industrial water reuse tank topology guide shows how a tank this size anchors grey-water, rainwater, and HVAC condensate aggregation trains.
