The Enduraplas 1400 Gallon Black Vertical Storage Tank is a polyethylene vertical storage tank built for bulk above-ground water service where a sizable on-site reserve matters. It holds 1,400 gallons in an 80-by-80-inch base and stands 79 inches tall, giving you a wide, stable footprint rather than a tall, tippy profile. The black exterior blocks light through the tank wall, which slows algae growth in stored water far better than a translucent or natural tank.
Will it work for your site?
This is a vertical storage tank rated to a specific gravity of 1.9, so the wall is engineered to carry contents considerably denser than water. Full of water at 1,400 gallons, the tank and contents weigh about 11,676 pounds; at its maximum rated contents weight the same shell carries up to 22,184 pounds. Those two numbers, not the empty weight, are what your pad and any anchoring must be designed around. Plan the slab from the 80 x 80 inch (6.7 ft square) base, and size and reinforce that pad to the loaded 22,184 lb maximum using the framework in our guide on concrete pad sizing for above-ground polyethylene tanks. Don't forget the vertical dimension: at 79 inches tall, you'll want roughly 8 to 9 feet of overhead clearance for ladder access and a fill line, so check ceilings, eaves, and overhangs as well as the slab. If you are sizing the reserve itself against demand, draw-down, or refill rate, run the numbers in the Tank Sizing Calculator and check the method in the Tank Sizing Guide.
Fittings and the mistake to avoid
Fitting, outlet, and gasket or bulkhead configuration is not specified in this listing, so confirm port count, size, and gasket material with us at 866-418-1777 before ordering. That way the plumbing connection and gasket are matched to your service rather than assumed. The bigger mistake to avoid: don't let the 1.9 specific-gravity rating tempt you into chemical service without checking the chemistry first. That rating tells you the wall can carry weight up to about 1.9 times the density of water, not that the polyethylene resists a given chemical. The upside of that headroom is real for water duty, the shell is paying for roughly 10,500 pounds of carrying capacity it never uses on pure water, so if you later move to a denser, verified-compatible fluid the tank is already engineered for the load. But for anything beyond water and water-reuse, confirm compatibility first.
Common uses and freight
At 1,400 gallons this size is a frequent pick for rural and remote water reserves, including private fire-protection storage where a fixed volume has to be on hand at all times; our write-up on fire-water reservoir tank design for rural and remote sites walks through the NFPA 22 sizing discipline and freeze-protection engineering that apply in cold climates. The black wall picks up solar heat that helps a little in cold service, but for sub-freezing duty follow that freeze-protection method rather than relying on color alone. It also serves well in industrial water-reuse and rainwater-aggregation trains, covered in our industrial water-reuse tank topology guide. This tank ships LTL freight from the Neche, North Dakota plant, with the carrier rate quoted live to your ZIP code rather than included in the list price.
