The Snyder Industries 12500 gallon vertical liquid storage tank is a full-bulk HDPE vessel built for high-volume water and liquid storage where footprint efficiency and tall vertical capacity matter. It stands 198 inches (about 16.5 ft) tall on an 11 ft 10 in (142 in) square footprint, holds 12,500 gallons, and carries a 1.4 specific gravity rating and ASTM certification - so you have real engineering headroom above plain water. If you have been searching for a large vertical HDPE storage tank from Snyder, this is the upper end of the polyethylene vertical line.
Will it work for your site
This is a white polyethylene vertical tank rated to a 1.4 specific gravity, meaning the wall is engineered to hold liquids up to 1.4 times the weight of water. Filled with plain water (SG 1.0) the contents weigh 104,250 lb; at the tank's maximum rated SG of 1.4 the contents reach 145,950 lb. That 145,950 lb max-rated case is the number your foundation, seismic, and wind checks must be sized to if you ever run a liquid heavier than water - not the water weight. A vessel this size demands a properly designed, level concrete pad, so work the load through our concrete pad sizing guide for above-ground polyethylene tanks (the ACI 360R-10 framework and ACI 318 boundary) before you pour. With an 11 ft 10 in square footprint and a 16.5 ft height, cross-check overhead clearance for fill, vent, and inspection access. No fitting or outlet configuration is published for this SKU, so call 866-418-1777 to confirm the fitting layout before you order.
Sizing it right
At 12,500 gallons this tank sits at the top of the vertical polyethylene range, so size to your actual draw and refill cycle rather than buying capacity you will never turn over. Our Tank Sizing Calculator and Tank Sizing Guide walk you through usable volume versus nameplate gallons. The 1.4 rating is the ceiling for this tank; if your liquid runs heavier or you need secondary containment, the Snyder Captor double-wall freeboard sizing guide covers the freeboard and density math per ASTM D1998. For fire-protection reservoir duty, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate sites - relevant if this tank anchors a private fire stack.
The mistake to avoid
On a tank this tall, wall thickness is heaviest at the base and tapers upward, and the vapor-saturated headspace zone behaves differently than the liquid-wetted wall. Operators who only inspect the liquid side miss where premature failures actually originate. Read the HDPE tank wall thickness guide for the ASTM D1998 wall-thickness sizing logic before you set an inspection schedule. And confirm your liquid's specific gravity against the 1.4 rating - exceeding it overstresses the wall regardless of how the tank looks. See the technical drawing on this page for dimensions and port detail.
