The Enduraplas 5050 gallon dark green vertical water storage tank holds 5,050 gallons in a single upright footprint measuring 120 inches in diameter and 120 inches tall - a 10-foot by 10-foot envelope on its pad. Molded from polyethylene with a 1.1 specific gravity rating, this vertical storage tank is built for bulk water duty: irrigation supply, rainwater aggregation, fire-protection reservoirs, and the high-volume water storage that ranches, farms, and remote sites depend on. The dark green color blends into outdoor surroundings better than a white or black tank.
Will it work for your site?
Plan the foundation around the loaded weight, not the empty shell. Filled with water this tank carries roughly 42,117 pounds, and at its 1.1 specific gravity rating the maximum rated contents weight reaches about 46,329 pounds. That load sits on a 120.0 x 120.0 inch footprint, so the pad underneath has to be engineered to bear it - a poured, reinforced pad sized for the load is not optional at this scale. Work through the math in our concrete pad sizing guide before you order, and confirm the tank volume matches your demand with the Tank Sizing Calculator and Tank Sizing Guide. Because the wall is rated to 1.1 specific gravity, this vertical tank also handles water-based solutions slightly heavier than plain water - up to 1.1 times water weight - without re-rating, which gives you room for light brine, fertilizer mixes, or treated water alongside straight potable-grade storage planning.
Sizing it into a larger system
At 5,050 gallons this tank is large enough to anchor a real storage train rather than serve as a stopgap. If you are designing a private fire-protection reservoir, the NFPA 22 sizing discipline and cold-climate notes in our fire-water reservoir design guide walk through how a polyethylene tank fits the stack - and for outdoor service in a cold climate, plan freeze protection (heat trace, insulation, or a below-frost-line draw) using that same guide. For grey-water, rainwater, and HVAC-condensate aggregation, the quality-banded approach in our industrial water reuse topology guide shows where a vertical tank of this size belongs.
Plumbing, offload, and the mistake to avoid
Fitting configuration - bulkhead outlet, fill, and vent - and gasket material should be confirmed before you order, so call 866-418-1777 to spec the outlet and gasket for your plumbing. At 10 feet wide and 10 feet tall, confirm gate width, overhead clearance, and crane or forklift offload before the truck arrives, since there is no liftgate option for a tank this size. The error that bites buyers most often is putting the tank into service without a controlled first fill: a 5,050-gallon vertical tank loads its pad with tens of thousands of pounds, and an uneven or settling foundation can stress the base before you notice. Fill it in stages, watch for pad settlement, and check every fitting for leaks during the hold - the discipline is laid out in our hydrostatic test methodology guide.
This tank ships LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP code. Because it ships from a single Texas plant, freight scales with distance - get your ZIP quote before comparing total cost.
