The 65 Gallon Vertical Liquid Storage Tank from Norwesco is a compact polyethylene vertical storage tank built for tight footprints: 23 inches in diameter and 43 inches tall, holding 65 gallons. It carries a 1.5 specific gravity rating, meaning the tank wall is engineered for liquids heavier than water up to that density. At 23 inches in diameter it clears a standard 24-inch interior doorway opening, and the 43-inch upright height fits under most 80-inch door headers, so this Norwesco vertical tank moves into corners, utility closets, and back rooms that taller storage tanks cannot reach.
Will it work for your liquid
Filled with plain water (specific gravity 1.0), this tank holds roughly 542 pounds of contents. Because the shell is rated to 1.5 specific gravity, its maximum rated contents weight climbs to 813 pounds, giving you headroom for denser fluids without exceeding the design rating. Confirm your liquid's specific gravity stays at or below 1.5 before you fill. The top opening uses the manufacturer-specified 60002 lid shown on the technical drawing on this page; any gasket or seal at that opening must match the 60002 lid spec, so verify the sealing hardware against the drawing rather than assuming a vented or fully sealed configuration. The technical drawing also documents the opening layout, so confirm any outlet or bulkhead fitting locations against that drawing before you order bulkhead fittings or gaskets.
Sizing the pad and stand
At 23 inches diameter, the footprint is small, but a full tank still concentrates 542 pounds of water (more with heavier liquids) onto that base, so a level, continuous-support surface matters. Size your stand or pad for the 813 pound maximum rated load, not the 542 pound water figure, if you will ever run a liquid heavier than water. For above-ground installs, our concrete pad sizing guide walks through the ACI 360R-10 framework for slab support under polyethylene tanks. If you are still narrowing capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match gallons to draw rate and refill cycle. For cold-climate water storage, the fire-water reservoir and freeze-protection guide covers protecting stored water in unheated spaces.
The mistake to avoid
The common error on a vertical storage tank like this is over-filling with a liquid denser than the 1.5 specific gravity rating, or assuming a water tank will tolerate any liquid. The 1.5 rating is the structural ceiling for fluid density, not a chemical-service endorsement. Match your liquid's specific gravity to the rating, support the full 813 pound loaded weight, and use the documented 60002 lid opening as shown on the drawing.
