The Enduraplas 1550 Gallon Polypropylene Vertical Tank stands 125 inches tall on a 64 x 64 inch square footprint, giving you 1,550 gallons of bulk storage in a compact ground area. It carries a 1.9 specific-gravity wall rating (per the model designation), which is engineered headroom, not a requirement: filled with water the tank only loads its wall to roughly 1.0 SG, so that 1.9 rating means you are running the tank well inside its structural envelope. Whether you are staging fire-reserve water, harvested rainwater, industrial process water, or reclaimed grey-water, this vertical is built to hold a full column of it and keep holding.
Will it work for your site?
At 1,550 gallons the tank carries 12,927 pounds when filled with water to the brim, so plan the pad and the fill logic around that number. The footprint is a true 64.0 x 64.0 inches, which lets it sit on a modest square pad while still reaching useful vertical capacity at 125 inches of height. Run your target draw-down and refill cycle through the Tank Sizing Calculator and the Tank Sizing Guide before you commit to a location — for tall vertical tanks the loaded weight, not the floor area, is what governs the foundation. See the technical drawing on this page for the port and outlet layout.
Foundation and cold-climate planning
A vertical tank this size needs a level, engineered base rated for the full loaded weight. Do the math up front: 12,927 pounds spread across a 64 x 64 inch footprint (28.4 square feet) works out to about 455 pounds per square foot of bearing load on the pad — that is the number a foundation engineer actually designs to. Our guide on concrete pad sizing for above-ground poly tanks walks the ACI 360R-10 framework so the slab is sized correctly the first time. If the tank will hold a fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate service. For reuse duty — rainwater, HVAC condensate, or grey-water aggregation — the industrial water reuse topology guide and the rainwater harvesting first-flush guide show how this vertical fits a quality-banded storage train.
The mistake to avoid
The 1.9 SG rating is the point — do not read it as a signal to reach for a heavier tank than you need, and do not read it as license to ignore what you are storing. For water and the reuse duties above, this wall is running with margin to spare. If you ever change service to a denser liquid, match the actual specific gravity of that liquid against the tank rating before you fill, and size fittings and outlets for the flow you actually need rather than defaulting to whatever port is closest. See the technical drawing on this page for the port and outlet layout before you plumb.
