The Enduraplas 5050 Gallon Black Vertical Storage Tank (SKU THV05050B) is a heavy-duty polyethylene reservoir built for large-volume water storage where a compact footprint matters. It holds 5,050 gallons in a body that stands 120 inches tall over a 120 x 120 inch footprint, so a full tank of water weighs roughly 42,117 pounds and the pad below it carries that load year-round. The black polyethylene wall blocks sunlight, which suppresses algae growth in stored water and makes this vertical storage tank a practical choice for bulk water, irrigation supply, fire-water reserve, and industrial process water.
Will it work for your site?
Match the tank to the load, not just the volume. This vertical tank carries a 1.9 specific gravity rating, meaning the wall is engineered for contents up to about 80,022 pounds. Plain water loads it to only 42,117 pounds - roughly 53% of that rated structural capacity - so for water service the tank runs with a wide margin of safety, and the governing number your foundation must support is the full-water weight. The footprint is 120.0 x 120.0 inches; plan a level, continuous pad sized for the standing load. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm capacity and clearances before you commit, and our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for supporting a tank this heavy.
Fittings and reference drawing
Review the technical drawing on this page for outlet, fitting, and manway locations along with confirmed dimensions before you order plumbing components. For fire-water reserve and remote-site applications, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection, and if you are aggregating grey-water, rainwater, or HVAC condensate, our industrial water reuse topology guide shows how a bulk tank like this fits a quality-banded storage train.
