The Enduraplas 1550 Gallon Beige Vertical Water Storage Tank is a polyethylene bulk-storage vessel built for water-storage duty including fire-water reserve, irrigation, and water-reuse trains. It stands 80 in H x 85 in diameter on an 85 x 85 inch footprint, holding 1,550 gallons in a single beige tank engineered for outdoor service. The beige color reduces algae-promoting light transmission compared with lighter or natural tanks; beige is not fully opaque, so for long-dwell storage, siting the tank out of direct sun further limits algae growth. Spec your doorway clearance, pad form, and overhead room against that 80 in height before delivery.
Will this tank work for your water system?
Full of water, this tank carries roughly 12,927 pounds of contents, and it is rated to a maximum content weight of 14,220 pounds, which gives you headroom for water and any light treatment additives. The specific-gravity rating of 1.1 means the wall is built for fluids up to 1.1 specific gravity (about 9.17 lb/gal), so standard municipal, well, rainwater, and grey-water duty all sit comfortably inside the envelope. Before you size the pad and plumbing, run your demand numbers through the Tank Sizing Calculator and the Tank Sizing Guide so the 1,550-gallon capacity matches your draw-down and refill cycle rather than your gut feel.
Pad, plumbing, and install discipline
An 85 x 85 inch footprint loaded near seven tons demands a flat, fully supporting base. A polyethylene vertical tank transfers its entire wet weight straight down through the floor, so the pad has to carry the load evenly with no voids or high spots. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that base right. Once the tank is set, prove the install before you trust it: our hydrostatic test methodology covers water-fill discipline, pad-settlement monitoring, and fitting leak detection with real hold-time math. Inlet, outlet, and any manway sizes and locations are per the technical drawing on this page, not assumed, and no fitting or gasket kit is bundled with the tank, so plan your plumbing connections from that drawing.
The mistake to avoid
The common error on a tank this size is treating it as a chemical tank. This is a water-storage vessel rated to a specific gravity of 1.1; it is sized for water and water-adjacent fluids, not for dense or aggressive chemistry. If your application drifts toward storing heavier or reactive liquids, do not try to upgrade this SKU; request a higher-SG-rated tank by calling 866-418-1777 instead. The second mistake is under-building the base. A seven-ton wet load on an uneven or undersized pad invites settlement, fitting stress, and premature wall fatigue, so treat the foundation as part of the tank, not an afterthought. Plan receiving as well: you must arrange offload with a forklift or equipment rated for the tank's weight. If this is a fire reserve, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and for reuse setups see our industrial water reuse tank topology guide on banding grey-water, rainwater, and condensate.
