The Enduraplas 5050 gallon green vertical storage tank (part THV05050G) is a single large-volume polyethylene reservoir built for bulk water storage where capacity and a stable footprint drive the decision. It holds a nominal 5,050 gallons in a body that stands roughly 120 inches tall on a square 120 x 120-inch footprint, so plan your pad around that plan area. Green resin cuts light transmission into the water, which helps hold back algae growth in outdoor water service, and this is exactly the kind of heavy-duty vertical storage tank people reach for when a smaller reservoir has run out of room.
Will it work for your site?
Filled with water, this tank carries about 42,117 pounds of contents, and the pad, ring wall, or compacted base underneath it has to be engineered for that dead load plus the tank weight. Here is the number that matters for anything denser than water: the molded shell is rated to a specific gravity of 1.9, which puts the maximum rated contents weight at roughly 80,022 pounds. Water sits at a specific gravity of 1.0, so on plain water duty you are operating with a wide structural margin, and if you ever store a heavier fluid you can divide its specific gravity into that 1.9 rating to find your safe fill level. Confirm the exact diameter and fill height against the technical drawing on this page before you pour concrete. To match this volume to your real demand, run the numbers through our Tank Sizing Calculator and read the Tank Sizing Guide.
One body, water today and denser service later
That SG 1.9 rating is the quiet differentiator on this tank. The same shell qualifies for heavier-than-water fluids all the way to a specific gravity of 1.9 without stepping up to a different tank, so one purchase covers plain water storage now and a denser fluid down the road. The mistake to avoid is treating that rating as a fill-to-the-top license with a heavy liquid: as specific gravity climbs, your safe fill volume drops, so size the fill to the fluid, not the gallon mark.
Foundation and application planning
A vertical tank this heavy needs a correctly sized, level base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for a load like this. If the tank is going into a fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, and condensate reuse layouts, see our industrial water reuse tank topology guide.
Freight and ordering
This tank ships LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP code rather than bundled into the list price. Get a real number for your delivery address with our Freight Cost Estimator, or call 866-418-1777 to confirm plant lead time and set up delivery. Because a 5,050 gallon vertical tank is an oversized freight item, plan for a forklift or other offload equipment at the receiving end.
