The Enduraplas 1320 Gallon Vertical Rainwater Harvesting Tank (SKU 45463) in Forest Green sits above ground and holds a full season of captured roof runoff on a compact 82-inch-square footprint. It stores 1,320 gallons of harvested water in a single vertical poly cylinder that tucks against a wall, at the corner of a barn, or beside a pump shed without eating up yard space. If you are matching tank volume to roof catchment area and local rainfall, run the numbers first with the Tank Sizing Calculator and Tank Sizing Guide before you buy.
Will it work for your site
This is a vertical storage tank listed with an 82.0 x 82.0 inch footprint and a 72-inch height from launch data; verify the final height and diameter against the technical drawing on this page before you pour a pad, since that same drawing is the reference for the fitting layout. The confirmed outlet on the drawing is a single 1-inch NPT bulkhead fitting. The seal is integral to the bulkhead, and the connection threads 1 inch NPT. Inlet and overflow provisions are not called out on the sheet, so confirm those with us before you plumb a downspout, first-flush diverter, or pump line. The forest green shell blocks light to slow algae growth in stored rainwater, which matters for non-potable irrigation, livestock, and fire-reserve harvesting.
Rated for water service only
This tank is built for water and rainwater harvesting. No elevated specific-gravity rating is published for it, so keep it to water and non-potable harvested runoff; do not use it for chemicals or high-specific-gravity liquids. If your project involves anything heavier than water, call us before you order and we will point you to the right tank.
Plan the pad for a full tank
Water is heavy. Filled to 1,320 gallons this tank weighs roughly 11,009 pounds, and every pound of that load sits on the 82 x 82 inch base, about 236 pounds per square foot of bearing pressure. That is a concrete-pad decision, not a gravel-and-hope decision. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework with that distributed load as the design input, so the slab carries the tank without cracking or settling.
Rainwater harvesting and fire reserve
Sizing a harvesting system by state rules and rainfall is its own discipline. See rainwater harvesting tank sizing by state and, for first-flush diverter math, the Texas Manual on Rainwater Harvesting first-flush guide. If this tank doubles as a rural fire-water reservoir, the NFPA 22 reservoir design guide covers sizing and cold-climate freeze protection.
