The Enduraplas 1350 Gallon Dark Green Vertical Water Storage Tank is a polyethylene vertical water tank built for bulk fresh-water storage on farms, jobsites, rural homesteads, and fire-reserve installs. It holds 1,350 gallons and carries a 1.1 specific gravity rating, which means it is rated for water and light water-based contents up to roughly 10 percent denser than plain water. Notably, this is a low-profile vertical: at 71 inches tall on an 85-by-85-inch footprint, it is wider than it is tall, which lowers the center of gravity and keeps the pad height requirement down.
Will it work for my site?
Match the tank to your space and your load before you buy. The footprint is 85 by 85 inches, so plan a level pad at least that wide, plus working clearance around the perimeter. Empty handling is one thing; full is another. At capacity this tank carries about 11,259 pounds of water, and it is rated to a maximum contents weight of roughly 12,385 pounds at its 1.1 specific gravity rating. That works out to about 1,126 pounds of density headroom over plain water before you reach the tank's contents rating. That full loaded weight is what your pad and ground have to support, so size the foundation for the contents, not the empty shell. If you are working out how many gallons you actually need or whether 1,350 is the right step, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before committing.
Foundation and install
A vertical storage tank this size needs a flat, fully supported base. A poured concrete pad is the standard choice for above-ground polyethylene tanks; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the pad matches the loaded weight above. Fitting and outlet configuration is confirmed per order, so call 866-418-1777 to verify the outlet, bulkhead, and gasket setup for your plumbing before you buy. After the tank is set, do a controlled water fill and watch for pad settlement and any fitting leaks before you put it into service; our hydrostatic test methodology guide covers the fill discipline and hold-time math for new-install acceptance. For rural fire-water reserve duty, the fire-water reservoir tank design guide covers NFPA 22 sizing and freeze protection for cold-climate sites.

The mistake to avoid
The most common error on a tank this size is treating it as a fresh-water vessel and then filling it with something heavier than the rating allows. This tank carries a 1.1 specific gravity rating, which suits water and light water-based contents. If your contents are denser than 1.1 specific gravity, this is not the right tank; you need a higher specific-gravity-rated tank, typically 1.5 or 1.9 SG service. Confirm the contents against the 1.1 rating first, and call 866-418-1777 before you fill it so we can point you to the correct specific gravity tank.
