The Enduraplas 5050 Gallon Vertical Water Storage Tank in black is a large-volume bulk water tank built for stationary above-ground service, holding 5,050 gallons in a single vertical polyethylene body. It measures 129 in in diameter and stands 96 in tall, so its footprint is a circle roughly 129 in across - not a square - which matters when you size the pad. Before anything else, confirm you have a level, engineered pad that fully carries that circular base. A tank this size is a fixed installation: it gets filled where it sits and stays there.
Will it work for your site?
This is a vertical storage tank sized for high-demand water duty: rural and remote fire-water reservoirs, industrial water reuse and rainwater aggregation, process make-up water, and bulk non-potable water holding where the site allows a wide vertical body. The wide, low profile helps here - 96 in tall on a 129 in diameter base gives a low center of gravity, which is a steadier stance for a 42,000-plus-pound full tank than a tall, narrow body. It comes fitted with a vented manway for filling and access, plus a 2" bulkhead outlet; see the technical drawing on this page for the fitting layout and manway placement. This tank is rated for water and non-potable water service at standard water weight - confirm the specific-gravity rating with our team at 866-418-1777 before storing anything denser than water. If you are still deciding whether 5,050 gallons matches your draw and refill cycle, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide first. For fire-protection duty, our guide on rural fire-water reservoir design and NFPA 22 sizing discipline walks through reserve sizing and cold-climate freeze protection.
The pad is the part people get wrong
Filled to capacity, this tank carries roughly 42,117 pounds of water. That load has to land on a pad that will not settle unevenly, or the tank body takes stress it was never meant to carry. Because the base is round, a properly sized circular or square pad only needs to cover that 129 in circle - do not over-pour for a square that the tank never touches. Read our framework on concrete pad sizing for above-ground polyethylene tanks before you pour. The 2" bulkhead is a gasketed thru-wall fitting: seat its gasket correctly and use a proper 2" bulkhead-to-pipe transition, because it is the single most common leak point. Plan a hydrostatic fill test at commissioning to monitor settlement and watch that bulkhead for leaks under real load. If you are aggregating grey water, rainwater, or HVAC condensate, our water reuse tank topology guide covers quality-banded storage trains.
Freight and next steps
This tank ships LTL freight, quoted live to your ZIP - a 5,050 gallon body is an oversized load, so get your delivery number early with the Freight Cost Estimator. For help confirming fittings, pad requirements, or the specific-gravity rating before you order, call our team at 866-418-1777.
