The Enduraplas 1650 Gallon Black Vertical Water Storage Tank is a polyethylene vertical storage tank built for bulk water on farms, rural fire-protection reserves, irrigation runs, and industrial water-reuse trains. It stands 73 inches tall on a 90-inch diameter footprint, holds 1,650 gallons, and carries a 1.1 specific-gravity rating, so it is sized for water rather than dense chemicals. The black resin blocks light, which suppresses algae growth in long-dwell water reservoirs where the tank sits full for extended periods outdoors.
Will it work for your site?
Plan your pad and plumbing around the real numbers, not estimates. A full water charge weighs about 13,761 pounds, and at the tank's maximum rated contents weight it carries roughly 15,137 pounds, so the slab and grade under it have to be engineered for that load before you fill. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 1,650 gallons matches your draw and refill cycle, and pour the foundation to the ACI 360R-10 pad framework so settlement does not stress the shell. Because this is a vertical tank, the 90 x 90 inch envelope describes a 90-inch round footprint — size a pad with full round clearance, not a true square slab. For exact fitting locations, outlet sizing, and overall geometry, see the technical drawing on this page.
The mistake to avoid
The number that trips people up is the 1.1 specific-gravity rating. This vertical storage tank is rated for liquids up to 1.1 SG, which covers water. If you are storing anything heavier than that, this is the wrong tank — you need a model rated for a higher specific gravity, so call us at 866-418-1777 before you buy and we will match the tank to your liquid. The second mistake is filling before the pad is ready: a tank carrying over 13,000 pounds of water has no tolerance for an uneven or under-built base. Run a controlled fill and watch for settlement using the hydrostatic test methodology for new-install acceptance before you commit the tank to service.
Fire and reuse service
For rural and remote sites, a 1,650-gallon polyethylene tank works as part of a private fire-protection stack — see the fire-water reservoir design guide for NFPA 22 sizing and freeze-protection in cold climates. If you are aggregating grey water, rainwater, or HVAC condensate, the industrial water-reuse topology guide shows where this size fits in a quality-banded storage train.
