The Enduraplas 750 Gallon Vertical Liquid Storage Tank (SKU 42902) is a straight-walled, upright polyethylene vessel built for bulk water and general water storage where floor space is tight but vertical clearance is not. It stands 107 inches tall on a 46 x 46 inch base, holding 750 gallons while occupying under four feet of floor in each direction. This is the "without fittings" configuration: the tank ships as a bare vessel so you specify and install the bulkhead fittings, outlets, and vent hardware your plumbing plan calls for, rather than paying for pre-drilled ports you would relocate anyway.
Will it work for your site?
Confirm two things before you commit: vertical clearance and the loaded weight your pad must carry. The 107-inch figure is the tank body alone - budget additional overhead for lid and fill access, and remember that standing it up from a 46-inch base needs more than 107 inches of vertical swing clearance to tip into place. Filled with water this tank weighs about 6,255 pounds, and that full water weight rides on the 46 x 46 inch (2,116 square inch) footprint - roughly 2.96 psi of bearing load, or about three tons concentrated on a small base. That number is the input your slab needs: our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework so the pad is engineered for the load, not guessed at. Run draw-down against demand with our Tank Sizing Calculator, and check capacity against your refill cadence with the Tank Sizing Guide.
The mistake to avoid
Do not order this bare-vessel version if you were expecting a plumbed-and-ready tank. "Without fittings" means no outlet, bulkhead, or vent is installed - you drill and fit it to your spec. Decide your fitting layout and elevation before delivery so you cut ports once, in the right place, and support the outlet line independently rather than hanging it off the tank wall. Just as important: the 750-gallon rating is for water at specific gravity 1.0. No SG rating is published for this bare vessel, so confirm the tank's specific-gravity rating with us at 866-418-1777 before storing any liquid denser than water. For a full walk-through of this size class, see the 750 gallon vertical (46" x 107") buyer's guide; if your clearance is tighter and you can trade footprint for height, the 48" x 103" version is the shorter, wider alternative. Use the technical drawing on this page to confirm exact dimensions against your space before you order.
Outdoor and cold-climate installs
This is a water and general-water storage vessel, and outdoor installs in cold climates need freeze planning before winter. The NFPA 22 sizing and freeze-protection guide covers freeze-protection engineering for cold-climate service and, if this is a rural fire-water reservoir, where a poly tank fits in the private fire-protection stack.
