The Enduraplas 1320 Gallon Vertical Water Storage Tank in black (SKU 45458) is a bulk polyethylene reservoir built for rural water supply, fire reserve, hauled-water storage, and industrial water reuse. It stands 74 inches tall on an 82-inch diameter round footprint, so it fits a compact pad while holding serious volume. Below are the answers to the three questions that actually decide this purchase: will it fit your site, how does it ship, and the one mistake to avoid.
Will it work for your site
Plan the pad for filled weight, not empty. At full water capacity this 1,320-gallon tank carries roughly 11,009 lb, so the slab or compacted base underneath has to support that load without settling. The tank stands 74 in tall on an 82-inch diameter round footprint, so plan an 82-inch-plus square or round pad. If you are still deciding between capacities or working out pad and clearance dimensions, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide before you commit. For above-ground poly installs, the concrete pad sizing guide walks the ACI framework for getting the base right under an 11,000-plus-pound filled load.
Fittings and configuration
The technical drawing on this page shows a vented manway cover with a 16-inch threaded opening for filling, inspection, and cleanout, plus a 2-inch bulkhead fitting for your outlet or plumbing tie-in. Confirm the fitting layout and thread callouts against the drawing before you order valves, camlocks, or bulkhead adapters so the plumbing lands where you need it. One field note on the 2-inch bulkhead: confirm its gasket or o-ring is rated for your service and torque it evenly per spec, because a bulkhead outlet leaks at the gasket, not the thread. The vented manway matters on a closed vertical tank too: it lets the tank breathe as it fills and draws down, preventing vacuum collapse or pressure buildup during transfer. Because the shell is black polyethylene, it blocks light transmission and suppresses algae growth in stored water, which is a real advantage for a standing water reservoir versus a translucent tank.
Freight and how to order
This 1320 gallon vertical water storage tank ships LTL freight on a pallet, quoted live to your ZIP code. Because freight on a tank this size depends on your delivery distance and site access, we quote it separately from the tank price rather than bundling it in. Get your number through the Freight Cost Estimator, or call 866-418-1777 and we will work out the shipment and confirm the fitting configuration with you. If this reservoir is headed into fire-protection or water-reuse service, the fire-water reservoir design guide and the water reuse topology guide cover the wider system design. New installs should also plan a proper acceptance fill using our hydrostatic test methodology to catch pad settlement and fitting leaks before the tank goes into service.
