Norwesco 20000 Gallon Black Vertical Storage Tank

The Norwesco 20000 Gallon Black Vertical Storage Tank is built for large-scale water storage where you need real volume in a single footprint - rural fire-water reserves, agricultural and irrigation supply, process water, and bulk reuse stores. It holds 20,000 gallons in a black polyethylene shell that stands 242 inches tall on a 165 x 165 inch base, and it carries a 1.5 specific gravity rating, so the wall is rated for contents up to 1.5 times the weight of water.

• Capacity: 20,000 gallons
• Footprint: 165 in x 165 in
• Height: 242 in
• Material / color: Black polyethylene
• Full water weight (SG 1.0): 166,800 lb
• Max rated contents (1.5 SG): 250,200 lb

Will this tank work for your site?

This is a vertical storage tank sized for serious capacity, so plan the site before it arrives. Full of water, the contents alone weigh 166,800 lb; at the full 1.5 SG rating the tank is rated to carry up to 250,200 lb of contents. That 1.5 SG rating is also a buying lever, not just a warning - for plain water it leaves more than 83,000 lb of structural headroom, so the tank is over-built for water duty and gives you room to store a denser solution later without re-tanking. A load like that demands an engineered foundation. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 20,000-gallon size fits your draw and refill cycle, and size the pad to the full 165 in x 165 in footprint and the 250,200 lb rated load using Concrete Pad Sizing for Above-Ground Polyethylene Tanks. For outlet and fitting placement, see the technical drawing on this page; because the fitting schedule isn't carried in the listing specs, confirm exact outlet sizes and locations against that drawing and by calling 866-418-1777 before you order.

How it ships

A 242-inch-tall, 20,000-gallon vertical tank moves by LTL freight, quoted live to your ZIP. This Norwesco tank ships from the nearest of three plants - Albertville, AL; St. Bonifacius, MN; or Washington Court House, OH - covering the Southeast, the Upper Midwest, and the Ohio Valley, so the closest origin to you sets the lane and keeps the haul short.

The mistake to avoid

The single most common error on a tank this size is under-building the pad. Buyers spec the foundation for the empty tank or the water-only weight and forget the SG headroom - at 1.5 SG this tank is rated to a contents load of 250,200 lb. Pour the pad for the full rated load on level, compacted ground sized to the 165 in x 165 in footprint, and verify outlet and fitting locations against the technical drawing on this page before you set it. If this tank is part of a rural or remote fire-water reserve, the design discipline in Fire-Water Reservoir Tank Design for Rural and Remote Sites covers NFPA 22 sizing and freeze protection; for grey-water, rainwater, and condensate aggregation duty, see Industrial Water Reuse Tank Topology.
