This 100 gallon HDPE vertical liquid storage tank in black is a compact, straight-wall polyethylene tank built for water and general liquid storage where floor space is tight. It stands 37" tall on a 31" x 31" footprint, giving you a full 100 gallons of usable volume without a wide base. The black high-density polyethylene wall blocks light to discourage algae growth, which makes it a practical choice for outdoor water storage, rainwater holding, hauling, and utility supply.
Will it work for your site?
Confirm two things before you order: the footprint and the filled weight. This tank occupies a 31" x 31" pad and reaches 37" in height, so measure your doorway, closet, trailer bed, or equipment skid against those numbers. Filled with water it carries roughly 834 lb of water alone, plus the weight of the tank itself, so the pad or platform under it needs to support that full dead load, level and continuous across the entire base. Vertical poly tanks are engineered to sit on a flat, fully supported surface, not on legs or point supports. If you are still deciding on capacity, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching gallons to your draw rate and refill schedule.
Freight and delivery
This tank ships LTL freight on a pallet, quoted live to your ZIP code. Enter your delivery ZIP in the Freight Cost Estimator for a rate, or call 866-418-1777 and we will quote it by phone. Because it moves by common carrier, plan for a curbside drop and have a way to move a tank of this size once it lands. Check the technical drawing on this page to confirm the overall height and width clear your access points before the truck arrives.
The mistake to avoid
The most common error with a black vertical tank like this is assuming the color rating covers your liquid. Black HDPE is chosen here for UV and light resistance to slow algae, not as a chemical-service rating. This tank is set up for water and general liquid storage. If you plan to store anything heavier than water or any chemical, confirm the resin and specific-gravity rating for your exact fluid before you fill it rather than assuming a water tank will hold it. It also helps to understand where poly tanks actually wear over time; our guide on HDPE tank wall thickness at the vapor-saturated headspace explains the ASTM D1998 sizing logic behind these tanks. For water, rainwater, and utility storage at 100 gallons in a small footprint, this one is a clean fit.
