The Enduraplas 1500 Gallon HDPE Vertical Liquid Storage Tank stores 1,500 gallons of water or a compatible liquid in a single upright cylinder that stands 137 inches tall on a 60.0 x 60.0-inch footprint. It is molded from high-density polyethylene and carries ASTM certification, so the wall build is dimensioned to a recognized standard rather than a shop guess. If you are matching a tank to a pad, a doorway, or an existing containment area, the verified 137-inch height and square 60-by-60-inch base are the two numbers to design around.
Will it work for your site?
Full of water this tank weighs roughly 12,510 pounds, so the pad or slab underneath it has to carry that load across the 60-by-60-inch base without settling or tilting. A vertical of this height wants a level, continuous-support foundation, and a full concrete pad is the safe default for a 1,500 gallon vertical. Confirm the 137-inch overall height clears any roof line, eave, or fill access before you commit; that is the dimension most often overlooked on tall verticals. Use the Tank Sizing Calculator and Tank Sizing Guide to check the capacity against your actual draw and refill cycle so you are not oversizing the footprint for water you never hold.
Sizing and standards
ASTM D1998 is the sizing logic that governs polyethylene verticals like this one, and it controls how wall thickness is distributed from the top down rather than uniformly. Our guide on HDPE tank wall thickness at the vapor-saturated headspace walks through why that distribution matters for inspection and service life. If this tank is headed for fire-water or bulk storage duty, the NFPA 22 fire-water reservoir guide and the API 2000 vent-sizing worked examples for 1500 to 10000 gallon verticals cover the venting and freeze-protection details that keep a tank this size healthy in normal service.
The mistake to avoid
Do not assume this tank is rated for anything heavier than water. No specific-gravity rating is published for this unit, so before you store any liquid denser than water, confirm the tank's specific-gravity rating for your fluid. A fertilizer or brine that a lighter-rated wall cannot carry is the classic way a poly vertical fails early. Match the fluid to the rating first, then finalize fittings, and confirm outlet and fitting locations with us before you plumb the tank.
