The Enduraplas 1650 Gallon Black Vertical Storage Tank (SKU THV01650B) is a polyethylene vertical tank built for straightforward bulk liquid storage. It holds 1,650 gallons, and the black polyethylene wall blocks light to discourage algae growth in stored water. If you are cross-shopping, this is the tank people find under searches for an Enduraplas vertical storage tank, a black vertical tank, or simply a large black water tank. For exact height and footprint dimensions, refer to the technical drawing on this page before you finalize your layout.
Will it work for your site?
Start with weight, because that is what dictates your pad and your placement. Filled with water this tank carries roughly 13,761 pounds of contents, so the ground under it has to be flat, fully supporting, and rated for that load across the entire base. Do not set a vertical tank of this size on gravel, timbers, or a partial pad. The tank is rated to a 1.9 specific gravity, which means the wall is engineered to hold liquids heavier than water up to a maximum contents weight near 26,146 pounds at full rating. For water service you are nowhere near that ceiling, so you have generous structural margin. Keep in mind that 1,650 gallons is the brim-full nominal capacity, not your typical operating volume, so if you are sizing for a draw-down and refill cycle, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide before you commit.
Foundation and application notes
A tank this size almost always wants an engineered concrete pad; our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework so your slab matches the load. This size and geometry are common in rural fire-water reservoirs, and our write-up on fire-water reservoir design for remote sites covers NFPA 22 sizing and cold-climate freeze protection. For reuse trains blending grey-water, rainwater, or HVAC condensate, see our industrial water reuse tank topology guide. Refer to the technical drawing on this page for fitting locations and exact dimensions before you plumb anything.
The mistake to avoid
The most common misstep on a large vertical tank is underbuilding the base. Water weight climbs fast, and any settling or point-loading under an uneven pad can distort the wall and stress fittings over time. Get the pad flat and fully supporting first, then plumb.
