The Enduraplas 900 Gallon Vertical Liquid Storage Tank (SKU 910900-1.5-NAT) is a white polyethylene vertical tank built for bulk water and liquid storage where you need real reserve volume on a compact, fully-supported pad. It holds 900 gallons on a roughly 72-inch-diameter circular base, and the flat-bottom vertical design is engineered to be filled, drained, and refilled on a working schedule sitting directly on a level slab or ring wall.
Will it work for your site
Start with the weight math, because that is what your foundation actually has to carry. Filled with water, this tank loads roughly 7,506 pounds onto its base — 900 gallons at 8.34 lb per gallon. That load has to be evenly supported across the full circular footprint, so confirm your slab, ring wall, or containment pad is level, continuous, and rated for it before you fill. Polyethylene tanks depend on uniform bottom support and do not tolerate point loads or unsupported spans. For the exact height, diameter, and outlet locations, check the technical drawing on this page and confirm your overhead clearance and pad size against it before you order. If you are still working backward from your daily draw or deciding between capacities, run the numbers with our Tank Sizing Calculator and the Tank Sizing Guide.
The mistake to avoid
This is a water and liquid storage tank, and the fittings, gaskets, and plumbing you hang off it have to match your actual service. Before you commit it to anything heavier than water — or to any chemical service — verify the required specific gravity rating and resin against the liquid you plan to store, and match the outlet and bulkhead hardware to suit. Don't assume a water tank is cleared for a denser or reactive liquid. Confirm the tank's rating first, then spec the hardware; call 866-418-1777 and we'll confirm available fitting and gasket options for this SKU. For fire-water and rural reservoir use, the NFPA 22 reservoir design guide covers sizing discipline and cold-climate freeze protection.
Sizing up or down
If 900 gallons is close but not exact, compare it against the neighbors in the vertical line. The 500 Gallon and 300 Gallon verticals step down for tighter spaces, while the 2000 Gallon steps up when you need more reserve.
