The Enduraplas 1650 Gallon Vertical Liquid Storage Tank (SKU 901650-1.9-NAT) is a bulk vertical polyethylene tank built for water and liquid storage where you need real capacity on a single pad. It holds 1,650 gallons in an 86-inch-wide body standing 78 inches tall, making it a fit for pressure-boost feed, irrigation buffering, hauled-water storage, or a rural fire-water reserve. Dimensions on this unit are verified from launch data, and the technical drawing on this page shows the tank profile and outer dimensions — worth a look, since an 86 x 86 x 78 body is squatter than a typical tall vertical, so confirm the drawing matches your headroom and door clearance before you order.
Will it work for your site?
Two numbers drive this decision: footprint and full weight. The tank sits on an 86.0 x 86.0 inch footprint, so plan a level, compacted, full-diameter pad at least that size — a partial base is not an option on a tank this size. Filled with water it carries 13,761 pounds, so the pad and any structural deck beneath it must be rated for the full loaded weight, not the empty shell. If you are still choosing a capacity, run your daily-draw and refill math through our Tank Sizing Calculator and the Tank Sizing Guide before you commit — sizing a vertical storage tank to the real duty cycle is cheaper than buying a second tank later.
The mistake to avoid
This is a water-service tank. The specific-gravity rating is not verified in our data for this SKU, so do not trust the "1.9 SG" string in the product name as a spec — confirm the exact rating against the manufacturer's tag and drawing before you store any liquid heavier than water (SG greater than 1.0). Filling a tank with a fluid denser than its rated specific gravity is the single most common way these tanks fail early. For plain water you are on solid ground; for anything heavier, verify the rating with us first at 866-418-1777.
Fittings and system fit
Fitting sizes and gasket material for this SKU are not yet listed on this page — call 866-418-1777 to confirm outlet and bulkhead size, and EPDM versus Viton gasket for your fluid, before ordering. If this tank is part of a private fire-protection or remote-site water plan, our guide on fire-water reservoir tank design and NFPA 22 sizing covers reserve-volume discipline and freeze protection.
