The Enduraplas 2500 Gallon Dark Green Vertical Water Storage Tank (SKU TLV02500DG) is a polyethylene vertical storage tank built for bulk static water storage where you need real volume in a compact footprint. It stands 113 inches tall on a 90-by-90-inch base, so a 2,500-gallon nominal capacity occupies a footprint just 90 inches square. The dark green color helps slow algae growth in outdoor installs and blends into rural and remote sites better than a white or black tank. If you are weighing this size against your actual draw and refill rate, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide before you commit to a pad size.
Will this water tank work for your site?
This is a 2,500-gallon vertical water tank rated to a specific gravity of 1.1, which covers water and water-based liquids up to that density. The polyethylene shell is built for water storage: livestock and irrigation supply, rainwater aggregation, and fire-water reserve are all common uses for a vertical storage tank this size. The dimensions matter as much as the gallons. At 113 inches tall, plan your fill plumbing, overflow, and any ladder or platform access around that height, and confirm the 90-inch square footprint clears your intended pad with room for fittings and service. Usable volume is less than the nominal 2,500 gallons and depends on outlet height and overflow setpoint, so check those against the technical drawing on this page. Fitting configuration is not listed for this SKU, so confirm outlet size, location, and overflow provisioning against the drawing before you finalize plumbing. For fire-protection duty, our guide on fire-water reservoir tank design for rural and remote sites walks through NFPA 22 sizing discipline and freeze protection for cold-climate service. For reclaimed-water programs, see our write-up on industrial water reuse tank topology for grey-water, rainwater, and HVAC condensate aggregation.
Plan the pad and the install weight
Weight is the number people underestimate. Filled with water, this tank carries roughly 20,850 pounds, and at its full 1.1 specific-gravity rating it can hold about 22,935 pounds of contents. That load sits entirely on the 90-by-90-inch footprint, so the supporting surface has to be engineered for it. A level, continuous, full-contact pad is not optional at this scale. Our breakdown of concrete pad sizing for above-ground polyethylene tanks covers the ACI 360R-10 framework and where the ACI 318 boundary applies. Once the tank is set, follow a disciplined fill on first use: our hydrostatic test methodology for new-install acceptance covers water-fill discipline, pad-settlement monitoring, fitting leak detection, and hold-time math.
The mistake to avoid
The common error on a tank this large is treating the pad as an afterthought and chasing a density rating it does not have. The 1.1 SG rating sets the structural ceiling at roughly 22,935 pounds of contents, versus about 20,850 pounds for plain water at 1.0 SG. Do not exceed 1.1 SG; there is no higher-rated variant of this SKU, so if you are storing anything denser, this is not the tank for that service. Equally, do not skip pad engineering because the empty tank is light. The load is real only when full, and an unlevel or undersized pad is the most expensive mistake you can make here. Match the pad to the filled weight, confirm the height and footprint against your site, and you have a vertical storage tank that will serve for years.
This tank ships LTL freight from the Converse, TX plant, quoted live to your ZIP. The 90-inch square footprint and 113-inch height make it an oversize LTL item where dimensional handling drives the rate, so get your exact number with our Freight Cost Estimator rather than guessing. Shipping originates in Texas, so South-Central and Gulf-region buyers generally see the lowest LTL. For help nailing the rate, call 866-418-1777 and we will quote it with you. Freight is quoted separately from the listed tank price.
