The 100 Gallon HDPE Vertical Liquid Storage Tank in Green is a compact, upright polyethylene tank built for water and general liquid storage where floor space is tight. It holds 100 gallons in a 31 by 31 inch bounding footprint and stands just 37 inches tall, so it fits under low ceilings, inside utility rooms, on trailers, and in the corners of pump houses and equipment sheds. The green tint helps limit light penetration and keeps stored water out of direct view. If you are still confirming how much capacity your draw-down or reserve actually needs, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you buy.
Does this tank work for my job?
This is a vertical liquid storage tank molded from high-density polyethylene, dimensioned at 37 inches tall by 31 inches in diameter and occupying a 31 by 31 inch bounding footprint (dimensions verified against the launch spec). Confirm the outer measurements against the technical drawing on this page before you frame an enclosure or size a containment pad. Filled to 100 gallons of water, the tank and its contents weigh about 834 pounds, so the slab, deck, or platform beneath it has to carry that load without flexing, and the surface should be flat and fully supported edge to edge. For anyone using an upright poly tank in a cold-climate or backup-water role, our guide on fire-water reservoir design and freeze protection walks through the sizing discipline behind these decisions.
The mistake to avoid
The most common error with a vertical HDPE water tank is treating it as chemical-ready. This is a water-service tank; before storing anything heavier than water you need to confirm the tank's specific-gravity rating supports the fluid's density, and that value is not published in this listing. Do not assume it. The other quiet failure point is the vapor-saturated headspace above the waterline, where wall stress and premature cracking tend to originate long before liquid-side inspection catches them. The write-up on HDPE wall thickness and ASTM D1998 sizing logic explains why, and how to inspect for it.
