The Enduraplas 8000 Gallon Plastic Vertical Liquid Storage Tank (SKU THV08000) is a large-volume vertical polyethylene tank built for bulk water and aqueous non-potable duty where you need real capacity in a fixed footprint. It measures 142 inches tall on a 144 x 144 inch base, which makes it a low-profile, squat vertical — roughly 12 feet across and 11.8 feet tall — not a tall narrow silo. Set your footprint expectation to a full 12-foot square. Every dimension here is verified against launch spec data, which matters when you are laying out a pad and clearances before the tank arrives.
Will it work for my site?
This is a vertical bulk water storage tank sized for high-volume duty: rural and remote fire-water reservoirs, industrial process water, rainwater and grey-water reuse trains, and general non-potable bulk water holding. Filled with water it carries a full water load of 66,720 pounds — that is the operating fill weight, distinct from the empty shipping weight, so size your slab to the full load, not the freight number. If you are engineering the slab, the concrete pad sizing framework (ACI 360R-10) walks through the load path for above-ground poly tanks this size. To confirm 8,000 gallons matches your draw and refill cycle, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide. One note on scope: this listing does not publish a specific gravity rating, so for anything denser than water (SG greater than 1.0) confirm the SG rating for that service by calling 866-418-1777 before you commit.
What to get right on a tank this large
The mistake to avoid on an 8,000-gallon vertical is treating headspace like dead space. On tall poly tanks the vapor-saturated zone above the liquid line is where premature wall failures tend to originate, and liquid-side inspection misses them. If this tank will run in demanding or long-service duty, read HDPE wall thickness at the headspace and the ASTM D1998 sizing logic before you order. Fitting detail matters too: outlet, fill, and vent sizes are not published in this listing, so confirm them before you finalize plumbing design — see the technical drawing on this page for the layout confirmed for this tank, and call us if you need the fitting schedule spelled out. For fire-protection reservoirs, the NFPA 22 sizing and freeze-protection guide covers cold-climate service; for reuse duty, see the water reuse tank topology guide.
Freight
A tank this size ships LTL freight and is quoted per destination. Get a live rate to your ZIP with the Freight Cost Estimator, or call 866-418-1777 and we will work out access, offload, and scheduling with you. Confirm your pad and site clearances against the 144 x 144 inch footprint before the truck rolls.
