The Enduraplas 1650 Gallon Vertical Water Storage Tank (SKU 901650-1.2-NAT) is a bulk polyethylene vertical tank built for stationary above-ground water storage — fire-water reserves, rainwater and reuse aggregation, and process make-up water. It stands 78 inches tall on an 86-inch diameter, a wide, low-slung profile that keeps the center of gravity down when the tank is full. The "1.2 SG" in the SKU is the rating that matters here: this shell is built to hold fluids up to about 20% denser than plain water (1.2 specific gravity), so it covers straight water service with headroom to spare. Dimensions on this listing are verified against launch data, so the numbers you plan your pad and site clearance around are the real ones.
Will it work for your site?
This is a 1,650-gallon vertical storage tank, 86 inches in diameter and 78 inches tall. Filled to capacity with water, it carries a full-water weight of 13,761 pounds — that is the load your pad, your grade, and your soil have to carry, not the empty shipping weight. Size a foundation for the full number, not the nameplate gallons, and plan a round-load pad under the full 86-inch diameter rather than a square one. If you are still confirming the capacity you actually need for your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit. A vertical poly tank of this size wants a full-contact, level, engineered base under the entire diameter — the concrete pad sizing guide walks the ACI 360R-10 framework for above-ground polyethylene tanks so the shell is supported edge to edge.
What it is good for
At this volume the tank fits the private fire-protection role well as a rural or remote fire-water reservoir; our NFPA 22 reservoir design guide covers sizing discipline and cold-climate freeze protection for exactly this kind of standby storage. It is equally at home in an industrial water-reuse train collecting grey-water, rainwater, or HVAC condensate into quality-banded storage. Reference the technical drawing on this page for the tank's port locations, and call 866-418-1777 to confirm the fitting and outlet layout for your service before you plumb it in.
Commission it right
The mistake to avoid on a new vertical tank of this size is skipping the acceptance test. Before you put it into service, fill and hold it — our hydrostatic test methodology guide lays out the water-fill discipline, pad-settlement monitoring, and hold-time math that catch a bad fitting or an under-built pad while the tank is still easy to drain, not after it is full of 13,761 pounds of water.
