The Enduraplas 6011 Gallon Dark Green Vertical Water Storage Tank is built for serious bulk water storage where a smaller tank would mean repeat deliveries or constant refilling. At 6,011 gallons on a 144-inch by 144-inch footprint, this is a large-capacity single-tank vertical option for ranch, agricultural, fire-reserve, and industrial water work. It is rotationally molded polyethylene from Enduraplas in Dark Green, an opaque color that blocks light through the tank wall to discourage algae growth and blends into outdoor sites better than white or translucent tanks.
Will it work for your application?
This vertical water storage tank is rated to a specific gravity of 1.1, meaning it is engineered to hold liquids up to 1.1 times the weight of plain water. For irrigation, rainwater capture, grey-water reuse, or fire-reserve duty, that rating gives you headroom over straight water. Full of water, the tank and contents weigh roughly 50,132 pounds, and the maximum rated contents weight is 55,145 pounds. Those numbers drive your site decision before you order: more than 25 tons concentrated on a 144 x 144 inch footprint is a permanent structural load that will find any soft spot, settle unevenly, and stress the tank wall. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm this capacity matches your draw-down and refill schedule before you commit. Storing liquids heavier than 1.1 SG, such as brine, liquid fertilizer, or chemicals? You need a higher-SG-rated tank rather than this water model.
Fittings and the mistake to avoid
The single most common mistake on a tank this size is under-building the foundation, so review our guide on concrete pad sizing for above-ground polyethylene tanks and its ACI 360R-10 framework before the tank arrives. Once the pad is set and the tank is filled, follow a disciplined hydrostatic test methodology to watch pad settlement and check every connection for leaks before you rely on it. The fitting package (outlet size, fill, overflow, and vent, with the matching gasket for your service) is configured per order on a tank this large, so call 866-418-1777 and we will spec the connections for your fill source, draw rate, and the gasket material right for your fluid. If this tank feeds a private fire-protection stack or a water-reuse train, our deeper guides on fire-water reservoir design and industrial water-reuse tank topology cover sizing and treatment-stage sequencing. See the technical drawing on this page to confirm dimensions, fitting locations, and clearances against your site plan.
Freight
This vertical storage tank ships LTL freight from the Enduraplas plant in Converse, TX, quoted live to your ZIP code. Freight covers the empty tank, not the loaded weight; an oversized tank this size is a dedicated-truck-class shipment, and offload requires customer-side equipment such as a crane or large forklift, so plan that ahead of delivery. Get your number in seconds with our Freight Cost Estimator, or call us at 866-418-1777 and we will work out delivery, offload, and placement details for a tank this size. Listed price is the tank only; LTL freight is quoted separately to your ZIP.
