Enduraplas 1100 Gallon Green Vertical Storage Tank

The Enduraplas 1100 Gallon Green Vertical Storage Tank is a 1,100-gallon polyethylene vertical storage tank standing 97 inches tall on a compact 60 by 60 inch footprint. It is built for above-ground bulk water storage where you need real capacity in a round, freestanding profile that does not sprawl across your site. The green color reduces light transmission compared to a translucent natural tank, which helps limit algae growth in water that sits for extended periods.

Will it work for your site

Size your foundation around the loaded weight, not the gallon number. Filled with water, this vertical tank carries roughly 9,174 pounds of contents. Its 1.9 specific-gravity rating means the shell is engineered to hold up to about 17,431 pounds of contents at full volume, so the same tank cross-serves heavier-than-water liquids up to 1.9 SG without stepping up to a different unit. For plain water storage that is simply wall strength rated well above what you will ever load it with; for a future job involving a denser fluid, it is buy-once headroom. The 60 by 60 inch footprint is what you size your pad to. Walk the numbers with the Tank Sizing Calculator and the Tank Sizing Guide before you set it, and if this tank feeds a rural fire-protection reservoir, our guide on fire-water reservoir tank design covers NFPA 22 sizing discipline and freeze protection for cold-climate service.

Set it on the right foundation

A vertical storage tank of this size needs a level, continuously supported base rated for the full loaded weight. A poured pad is the most common answer; our walkthrough on concrete pad sizing for above-ground polyethylene tanks lays out the ACI 360R-10 framework and where the ACI 318 boundary applies. If this tank is one node in a larger storage train for greywater, rainwater, or HVAC condensate, our piece on industrial water reuse tank topology covers how to band and sequence quality-staged storage, and the first-flush diverter sizing guide is worth a read for harvested-rainwater setups.

The mistake to avoid

Do not size the pad off the gallon count alone. The number that governs your foundation is the loaded weight, around 9,174 pounds with water, and the base has to carry that continuously and level. Setting a heavy vertical tank on uneven or undersized support is the failure that cracks a foundation or stresses the tank wall. The other thing to lock down before delivery: fitting and gasket configuration is shown on the technical drawing on this page, so confirm outlet size, location, and gasket spec against the drawing or by phone before you plumb it in rather than assuming a layout.

Freight

This tank ships LTL freight, quoted live to your ZIP code, from whichever of our two plants is closer to you: Converse, TX serves the South and Southwest, and Neche, ND serves the Upper Midwest and Plains, which keeps the LTL lane short and the quoted cost down.
