The Enduraplas 5050 Gallon Black Vertical Water Storage Tank is a full-size bulk water reservoir for ranches, rural fire-water reserves, irrigation supply, and industrial process water where you need to bank a large volume on a single footprint. Built from polyethylene with a 1.1 specific gravity rating, this vertical water storage tank holds 5,050 gallons inside a 120 in by 120 in cylinder - a square 10-foot by 10-foot footprint that stands 120 inches tall in black.
Will it work for your site?
This is a vertical storage tank rated for liquids up to 1.1 specific gravity, which covers water and water-based contents at that density or below. The 1.1 figure is a hard ceiling, not a suggestion - heavier brines and most chemicals run above it, so if you are storing anything denser than water, call 866-418-1777 before you order and we will spec a tank rated for your contents. Plan the foundation around the loaded weight, not the empty shell: filled with water this tank carries roughly 42,117 lb of contents, and at its maximum rated 1.1 specific gravity it holds up to 46,329 lb. That is over 23 tons sitting on a 120.0 x 120.0 inch footprint, so a properly sized, level pad is not optional.

The black resin is a deliberate choice for outdoor water storage - it blocks light penetration that drives algae growth in stored water, though it does absorb more solar heat than lighter colors. Work through the load math with our Tank Sizing Calculator and Tank Sizing Guide before you pour anything, and read Concrete Pad Sizing for Above-Ground Polyethylene Tanks for the ACI 360R-10 framework that governs a slab under this kind of load. Fitting configuration - outlet, overflow, vent, and manway - is confirmed at quote, so tell us how you plan to plumb the tank and we will lock the connections before it ships.
How it ships
A tank this size moves by LTL freight, quoted live to your ZIP. It ships from the Enduraplas plant in Converse, TX, and because it is built in Texas, the further you are from south-central Texas the more freight matters to your delivered budget - run your ZIP through the Freight Cost Estimator or call 866-418-1777 for help. A 10-foot-diameter, 10-foot-tall unit also needs equipment and access planned at the receiving end: confirm gate or door clearance and a forklift or crane rated for the empty shell, and lock down your offload before the truck rolls.
The mistake to avoid
The most common error on a tank this large is treating the pad and the commissioning as afterthoughts. The 46,329 lb maximum loaded weight has to land on engineered, settlement-controlled bearing - undersize or unlevel the pad and you risk the tank, not just the foundation. After setting it, fill and accept it correctly: our guide on Hydrostatic Test Methodology for New-Install Tank Acceptance walks the water-fill discipline, pad-settlement monitoring, and fitting leak-check that catch problems before the tank is in service. If this volume is feeding a rural fire reserve, the Fire-Water Reservoir Tank Design guide covers NFPA 22 sizing and cold-climate freeze protection; if you are aggregating grey-water, rainwater, or HVAC condensate, see Industrial Water Reuse Tank Topology.
