The Enduraplas 1200 Gallon Vertical Water Storage Tank (SKU 901200-1.2-NAT) is a polyethylene bulk tank built for stationary above-ground water storage. It stands 68 inches tall on a 76-by-76-inch footprint, so before you order, confirm the pad and the path: this tank needs a full 76-inch square of level, load-rated support and enough overhead clearance to bring in the top and set the lid. The "-NAT" suffix indicates natural (translucent) resin rather than a pigmented shell - confirm the color you need for outdoor UV and algae control before you commit. Everything below answers the three questions that decide the purchase: whether it fits your job, how it ships, and the one mistake to avoid on a tank this size.
Will it work for your site?
At 1200 gallons in a vertical storage configuration, this is a plain-water tank rated for water (specific gravity around 1.0) service: bulk water holding, rainwater and reuse collection, irrigation supply, or a private fire-water reservoir. Heavier-than-water contents - brine, liquid fertilizer, or chemicals above SG 1.0 - require a tank rated for that specific gravity, and that is not this SKU. The dimensions are verified from launch data - 68 in height, 76 in width, 76 in length - which matters when you are laying out a tank farm or fitting the unit under a roof or inside a containment berm. Confirm your inlet, outlet, and vent fitting sizes and gasket material for your plumbing before ordering, since those are set at your install. Run your draw-down and refill numbers through the Tank Sizing Calculator and the Tank Sizing Guide before you settle on 1200 gallons versus a size up or down.
Plan the pad for a full tank
Filled with water, this tank carries about 10,008 pounds over that 76.0 x 76.0-inch footprint - roughly five tons on a six-and-a-third-foot square. That is a foundation load, not a shipping weight, and it is the single number that governs your pad. A poured pad has to distribute the load without differential settlement, which is exactly what pulls fittings out of level and works the shell over time. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI 360R-10 framework, and if this is a new install, run the hydrostatic test methodology - a controlled water fill with settlement monitoring - before you put it into service. For rural fire-protection duty, the fire-water reservoir design guide covers NFPA 22 sizing and freeze protection.
The mistake to avoid
Do not treat a 76-inch footprint as forgiving. On a partial or unlevel pad, a 10,008-pound filled tank concentrates load on its low edge and works the sidewall every fill-and-draw cycle. Get the full 76 x 76 square supported and level from day one, and lay out your plumbing to the tank's verified dimensions. If you are aggregating grey-water, rainwater, or HVAC condensate, the water-reuse tank topology guide covers train sequencing.
