The Enduraplas 3000 Gallon Green Vertical Storage Tank (SKU THV03000G) is a polyethylene vertical storage tank built for bulk water and heavier-liquid holding. It is rated to a 1.9 specific gravity, so for water and many denser liquids the tank wall is not the limiting factor - your pad and anchoring are. It stands 125 inches tall on a 90 x 90 inch footprint, so before you order, plan for 125 inches of tank height plus room above that for fill and vent access, and size your slab for the full 90 x 90 base. The green color helps limit light penetration and algae growth in outdoor water service, while the vertical profile keeps the ground footprint tight for a 3000 gallon capacity. If you are still deciding on size, run the numbers through our Tank Sizing Calculator and Tank Sizing Guide first.
Will this tank work for my job?
Full of water, this tank carries about 25,020 lb of contents. At its maximum 1.9 specific gravity rating, contents weight climbs to roughly 47,538 lb. That high SG rating means the tank handles water and many heavier liquids without the wall being the constraint, but your foundation and site engineering have to be sized for the loaded weight you actually intend to store. This is the tank people search for as an Enduraplas vertical storage tank in the 3000 gallon class, and the deciding factor is almost always the site, not the tank.
Site prep and foundation
A tank this size needs a properly engineered, level foundation. The 90 x 90 inch footprint sits on a full-diameter pad, and at over 47,000 lb fully loaded at rated SG, the base support matters as much as the tank itself. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting the slab right. For rural fire-water reserves, the fire-water reservoir design guide covers NFPA 22 sizing, and because this tank stocks from a northern-tier plant in Neche, ND, cold-climate installs should engineer freeze protection or heat trace up front - that same guide covers the freeze-protection detailing. If you are aggregating grey-water, rainwater, or condensate, see our industrial water reuse tank topology guide. Cross-check dimensions against the technical drawing on this page before you pour.
The mistake to avoid
The common error on a tank this large is under-building the foundation for the weight you will actually store. Water alone is roughly 25,020 lb, and filling with a heavier liquid up to the 1.9 SG rating pushes contents toward 47,538 lb. Size your pad and anchoring for the loaded case, not the empty tank, and confirm your intended contents against the tank's ratings before filling.
