The Enduraplas 550 Gallon Dark Green Vertical Water Storage Tank (SKU TLV00550DG) is a polyethylene vertical tank built for above-ground bulk water storage where you need real volume on a compact pad. Finished in UV-stable dark green for outdoor service, it holds 550 gallons of water on a 60 x 60 inch footprint. If you are sizing a vertical storage tank for a farm, jobsite, or rural water supply, this is a straightforward, full-volume option engineered for the field.
Will it work for your site?
The numbers you need to plan the install are here. Filled with water, this tank carries roughly 4,587 pounds of contents, and it is rated to a specific gravity of 1.1 - meaning it is built to hold contents up to about 10 percent denser than fresh water, or up to 5,046 pounds. That density headroom is the practical edge over a water-only 1.0-SG tank: it lets the same tank handle slightly heavier liquids such as light brines and many liquid-fertilizer blends without de-rating, while still being right at home for plain bulk water. Confirm your pad is sized and level for the loaded weight before you fill - settlement under nearly two and a half tons is the most common avoidable failure. Run your volume against the Tank Sizing Calculator and Tank Sizing Guide if you are still deciding between sizes.
Fittings, pad, and install planning
A vertical water tank lives or dies by its base. Pour and cure a pad that carries the loaded weight evenly - our guide to concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so you do not over- or under-build. The outlet and fitting configuration for this tank is confirmed at the time of quote - call 866-418-1777 so we match the bulkhead and outlet to your plumbing before it ships. Once the tank is set, fill it slowly and watch for pad settlement and fitting weeps before service; our hydrostatic test methodology for new-install acceptance covers the fill discipline and hold-time math. For cold-climate or fire-protection reserves, see our fire-water reservoir design guide and freeze-protection notes, and for grey-water, rainwater, or HVAC-condensate trains see our water-reuse tank topology guide. Cross-reference the technical drawing on this page for exact dimensions and fitting locations before you finalize your layout.
Freight and ordering
This water storage tank ships LTL freight, quoted live to your ZIP, from the Enduraplas plant in Converse, TX. Because freight on a vertical storage tank this size depends entirely on your delivery address and accessorials, get your real number from the Freight Cost Estimator before you order, or call us at 866-418-1777 and we will quote it for you. Once you have your freight quote and your pad is ready, we will get your tank on the road.
