The Enduraplas 1320 Gallon Vertical Water Storage Tank in dark brown is a poly tank built for stationary bulk water storage - irrigation buffering, rainwater or reuse holding, and rural fire-water reserve. It stands 74 inches tall on an 82 x 82 inch footprint, so it drops onto a single square pad without a sprawling ground plan. Filled with water alone it carries roughly 11,009 pounds, and that loaded weight - not the empty tank - is the number your pad and site plan have to answer to.
Will it work for your site?
Capacity is 1,320 gallons in a vertical storage tank format. Water weighs about 8.34 pounds per gallon, so 1,320 gallons alone is about 11,009 pounds on the 82 x 82 inch base - and that figure excludes the empty tank shell plus any freeze-protection or insulation load, so the true design load your pad carries sits above 11,009 pounds. That concentrated weight is why a level, engineered pad matters here; walk through the numbers with our Tank Sizing Calculator and Tank Sizing Guide before you set it, and if the tank sits on new concrete, our guide to concrete pad sizing for above-ground polyethylene tanks covers the ACI framework. This pack lists no specific-gravity rating for the tank, so confirm the SG rating with us before storing any liquid heavier than water (SG greater than 1.0); as specified here it is a vertical bulk water storage tank, not rated in this pack for chemical service.
Fittings and access
The tank comes with a vented manway cover for top access and a 16-inch threaded lid, plus a 2-inch bulkhead fitting for outlet plumbing. The vent matters - it lets air move as you fill and draw down so the tank isn't pulling a vacuum or building pressure. See the technical drawing on this page for exact fitting placement and manway detail. A bulkhead fitting seals on its gasket, not its threads, so verify the bulkhead gasket or O-ring is rated for your fluid and torque the nut down to seat it evenly - that gasketed seal is where field leaks tend to start on poly tanks - and confirm the 2-inch bulkhead matches your discharge line before you plumb it.
Fit-for-purpose water storage
For rural and remote fire-protection reserves, our fire-water reservoir design guide works through NFPA 22 sizing and cold-climate freeze protection. If you're aggregating grey water, rainwater, or HVAC condensate, the industrial water reuse topology guide shows how a tank like this fits a quality-banded storage train. On any new install, run a proper acceptance fill using our hydrostatic test methodology to catch pad settlement and fitting leaks before the tank goes into service.
