The Enduraplas 6000 Gallon Black Vertical Storage Tank (SKU THV06000B) is a full-size polyethylene bulk storage vessel built for large-volume water and liquid holding. It stands 179 inches tall on a 110 x 110 inch square footprint, giving you 6,000 gallons of capacity in a stable vertical profile. The black polyethylene wall blocks light transmission, which limits the photosynthetic algae growth that plagues clear and translucent tanks in outdoor service, making this a practical choice for bulk water, rainwater aggregation, and rural fire-water reservoir duty.
Will it work for your site?
Empty, the tank arrives as a light polyethylene shell you can offload and set on the pad. Filled with water it becomes a roughly 50,040 pound dead load, so the pad and soil under it have to be engineered for that figure, not guessed at. Plan the base before the tank arrives - our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. If you are still comparing footprints and heights across sizes, the Tank Sizing Calculator and Tank Sizing Guide help you match volume to available ground.
What the 1.9 specific gravity rating means
The shell carries a 1.9 specific gravity rating, meaning the wall is rated for liquids heavier than water (1.0) - up to roughly 95,076 pounds of rated contents by weight. For plain water storage you have significant headroom in that rating, which is why this tank holds up well under long-term bulk water duty. Understand the boundary too: 1.9 is the ceiling, and any liquid above 1.9 specific gravity is outside this tank's rating. Confirm outlet and fitting locations, sizes, and gasket details against the technical drawing on this page before you set the pad and plumb the connections - those specifications are confirmed by the drawing at order.
How it ships, and the mistake to avoid
A 6,000 gallon vertical tank ships LTL freight on its own, and this one ships from the Enduraplas plant in Neche, North Dakota. The freight weight is the empty shell - the 50,040 pound figure is a foundation load, not a shipping load - so plan your crane or offload equipment for the shell and confirm site access. Because freight on a tank this size depends heavily on your delivery ZIP and access, we quote it live rather than bury it in the list price. The most common error on a tank this large is treating the ground like an afterthought: fifty thousand pounds of water concentrated on a 110 x 110 inch footprint will find any weakness in an under-built pad, and a tilted or settling base voids the structural assumptions the tank is designed around. Build the pad first, level it, and confirm it can carry the full water weight. For private fire protection, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and for reuse setups the water reuse tank topology guide covers quality-banded storage trains.
