The Enduraplas 1100 Gallon Dark Green Vertical Water Storage Tank is a polyethylene vertical tank built for bulk water storage where you need real volume in a compact footprint. It stands 97 inches tall on a 60-inch-diameter base, so it holds 1,100 gallons while seating on a 5-foot-square pad. The dark green color cuts light penetration to slow algae growth in outdoor service, and the 1.1 specific gravity rating means it is engineered to carry water and water-density liquids up to that SG.
Quick specs: Capacity 1,100 gal | Height 97 in | Diameter 60 in | Footprint 60 x 60 in | Filled water weight ~9,174 lb | Max-rated contents weight (1.1 SG) ~10,091 lb | Material polyethylene | Color dark green | SG rating 1.1 | Ships LTL from Converse, TX. Because a 97-inch, 10,091-lb-rated tank is an LTL shipment, price the freight first with our Freight Cost Estimator (quoted live to your ZIP).
Will this tank work for your site?
Sizing and pad design start with weight, not just gallons. Filled with water, this vertical storage tank carries roughly 9,174 pounds of contents; at its maximum rated SG of 1.1, contents can reach about 10,091 pounds. That load sits on a 60.0 x 60.0 inch footprint, so the pad underneath has to be flat, level, and rated to support the full filled weight without settling. Run your volume and load numbers through the Tank Sizing Calculator, and if you are deciding between sizes, the Tank Sizing Guide walks through how to match a vertical tank to your draw rate and refill cycle. For a permanent install, our guide on concrete pad sizing for above-ground polyethylene tanks covers the ACI framework for getting the foundation right under a load this size. Layout and fitting positions are detailed in the technical drawing on this page.
What to verify before you fill
The most common mistake on a vertical water tank this size is treating the pad as an afterthought. At over five tons filled, an uneven or undersized base will cause the tank to settle, stress the wall, and pull on plumbing connections. Before you commit the tank to service, run a hydrostatic test on the new install. Our hydrostatic test methodology guide covers the water-fill discipline, pad-settlement monitoring, and fitting leak-detection steps for accepting a tank before it goes live. Fitting and bulkhead/gasket configuration varies by unit, so confirm your outlet size and gasket spec by phone (866-418-1777) before ordering plumbing. The 1.1 SG rating defines the heaviest contents this tank is built to hold: that gives roughly 917 pounds of contents-weight headroom over plain water, so it also handles light water-density liquids up to 1.1 SG. Confirm your fluid's specific gravity stays at or under 1.1 before filling.
Common applications
This size handles farm and ranch water storage, rural fire-water reservoirs, rainwater harvesting, and industrial water reuse. If you are building toward private fire protection, our fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites. For collected-water systems, the industrial water reuse tank topology guide details grey-water, rainwater, and HVAC-condensate aggregation into quality-banded storage.
