The Enduraplas 3100 gallon green vertical storage tank is a polyethylene bulk-water vessel built for large-volume above-ground storage - farm and ranch water, rural fire reserve, irrigation supply, rainwater harvesting, and industrial process water. At 103 inches tall on a 100 x 100 inch footprint, it holds 3,100 gallons in a single vertical column, so it stores serious volume without spreading across your site. This is the full-size Enduraplas vertical storage tank people reach for when they want one tank instead of piecing together smaller drums.
Will it work for your site
The tank is molded from polyethylene in green, which cuts light penetration to slow algae growth in stored water. It carries a 1.9 specific gravity rating, meaning the wall is built to hold contents up to 1.9 times the weight of water - well beyond what stored water demands, which leaves real structural headroom for dense liquids. Filled with water, expect roughly 25,854 pounds of contents; at the full 1.9 SG rating the shell is engineered for up to 49,123 pounds. If you are still weighing capacities against your daily demand, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching gallons to draw-down.
The foundation is the whole job
The single most common mistake on a tank this size is underbuilding the base. A vertical poly tank concentrates its entire filled weight - up to 49,123 pounds at full rating - onto that 100 x 100 inch footprint, and any void, slope, or soft spot beneath the shell translates straight into wall stress. Above-ground poly wants a level, continuous, fully supporting pad, so size the concrete correctly using our concrete pad sizing guide before the tank ever arrives. Pour it flat and full-contact, rated for the load, and skipping that work is what turns a decades-long tank into a warranty claim. Fitting sizes, outlet placement, and inlet locations are shown on the technical drawing on this page - review it before you plumb, and call us to confirm anything you need pinned down.
Fitting a 3,100 gallon column into the system
A tank this size is a common backbone for a private fire-water reservoir or an industrial reuse train. If you are sizing for rural fire protection, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse topology guide shows how tanks of this size drop into a quality-banded storage train, and the rainwater harvesting guide covers first-flush diverter sizing.
This tank ships by LTL freight from the Enduraplas plant in Converse, Texas, quoted live to your ZIP code - freight on a 3,100 gallon tank is real money, so pull an exact number from our Freight Cost Estimator before you order.
