The Enduraplas 1100 Gallon Plastic Vertical Water Storage Tank (SKU WV43) in white is a polyethylene bulk storage vessel built for general water duty where you need real volume on a manageable pad. It carries 1,100 gallons on a roughly 86-inch round footprint, so if you are still confirming whether this is the right size for your draw-and-refill cycle, run the numbers through our Tank Sizing Calculator and cross-check the method in the Tank Sizing Guide before you commit.
Will it work for your site?
This is a vertical storage tank rated for 1,100 gallons on an approximately 86-inch diameter base. Because it is a round tank, size your pad or containment to that diameter as a circle, not a square. Filled with water, the tank and its contents weigh about 9,174 pounds, and all of that load lands on the footprint you set - which is why the base under it matters as much as the tank. Set this on a level, fully supported foundation (compacted gravel or a poured slab), not on soil that can wash out or heave. A vertical poly tank carries its load through the floor, so anything less than uniform, continuous support under the entire base invites stress cracking over time. Confirm the exact height and diameter against the technical drawing on this page and against your available clearance before you pour anything.
The mistake to avoid
The number-one error with a large vertical water tank is treating the base as an afterthought. At roughly 9,174 pounds full, a soft spot or an unsupported edge concentrates load and works the tank wall. Build a flat, load-rated foundation to the full diameter and keep the tank plumb. The second mistake is service scope: this white poly vertical tank is configured for water storage - non-potable water, irrigation, rainwater capture, and fire-reserve draft. It is not spec'd here for chemical service. If your application drifts toward stored process chemistry, that is a different tank with a specific-gravity rating and a fitting package matched to the fluid, so talk to us first rather than assuming a water tank crosses over. Fitting configuration (inlet, outlet, lid, vent) is confirmed at quote - call 866-418-1777 and we will lock the ports to your plumbing.
Water reserve and reuse duty
At 1,100 gallons, this tank fits well as a fire-water reserve, a rainwater or grey-water aggregation vessel, or a buffer in a water-reuse train. If you are sizing a private fire-protection reservoir, the discipline in our guide on NFPA 22 reservoir sizing and cold-climate freeze protection walks through how much usable volume you actually need. For reuse and aggregation layouts - grey-water, rainwater, and HVAC condensate collected into quality-banded storage - see our breakdown of reuse-capable polyethylene storage topology.
This tank ships LTL freight, quoted separately to your ZIP - get a live number from our Freight Cost Estimator or call 866-418-1777 and we will build the quote with you. Because a 1,100 gallon vertical poly tank is a large, light-but-bulky load, LTL handling and delivery access (liftgate, forklift, or dock) drive the freight cost, so tell us how the tank will come off the truck when you request the estimate.
