The Enduraplas 1000 Gallon Open Top Tank (SKU 501000-1.2-NAT) is an above-ground polyethylene reservoir built for straightforward bulk water storage, batching, and mixing where a lidless top makes filling, inspection, and manual access easy. It holds a nominal 1000 gallons on a square 87-inch by 87-inch footprint and stands 45 inches tall. Because both length and width measure 87 inches, plan your pad and clearances around that square footprint, and confirm the exact top profile against the technical drawing on this page before you pour. If you are still weighing capacities or footprints, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide first.
Will it work for your site?
This is an open-top tank, verified at 45 in high on an 87 x 87 in base. Because the top is open, the real constraint is overhead access for gravity fill, top-mounted mixing, and visual level checks, so leave working clearance above the rim rather than treating it like a closed, domed vessel. Plan for load, not just volume: at 1000 gallons of water this tank carries roughly 8,340 lb when full, so the pad has to be sized and level for that standing weight. A poured concrete pad is the right foundation here, and our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the base is engineered rather than guessed.
What ships, and common applications
The SKU suffix -NAT means this vessel is molded in natural, translucent polyethylene rather than an opaque color, so light passes through the wall; if you are storing water long-term where algae or sunlight exposure is a concern, plan to shade or cover the open top. It ships as a bare open-top reservoir with no pre-installed bulkheads, outlets, or gaskets, so inlet, outlet, and overflow plumbing is field-supplied. Open-top poly reservoirs like this serve rainwater collection and reuse, fire-water storage, and general process water holding. See our write-ups on fire-water reservoir design and NFPA 22 sizing, rainwater harvesting and first-flush diverter sizing, and industrial water reuse tank topology.
The mistake to avoid
Do not treat an open-top water reservoir as a chemical tank. This unit is specified for water service and carries no specific-gravity rating for heavier liquids or fertilizer solutions. If your fluid is anything other than water, stop and call us at 866-418-1777 for a chemical-service tank rather than assuming this one fits. Confirm the square footprint and open-top height on the technical drawing on this page against your available space and any plumbing you plan to run.
