The Snyder Industries 15000 Gallon HDPE Vertical Liquid Storage Tank is a Lincoln, Nebraska-built water and liquid storage workhorse molded from high-density linear polyethylene in white, carrying a 1.9 specific gravity rating that gives you real headroom above plain water service. At 234 inches tall on a 142 x 142 inch footprint, this is a large-format vertical tank for bulk water, fire-water reserves, agricultural supply, and process holding where a single big vessel beats a cluster of smaller ones.
Will this tank do the job?
Capacity is 15,000 gallons in a white HDPE vertical body. Size your slab and structure around the loaded weight, never the empty shell: filled with plain water this tank carries roughly 125,100 lb of contents, and at its full 1.9 specific gravity rating the maximum rated contents weight is about 237,690 lb. That 1.9 rating is the heavier-duty wall option - it means the wall is built to hold liquids denser than water, so if your liquid runs heavier than water (brine and certain ag or process liquids up to 1.9 SG), this tank covers it where a 1.0 to 1.5 SG vessel would not. Hand both numbers - 125,100 lb water and 237,690 lb at 1.9 SG - to your structural engineer before any pour. The 237,690 lb figure is the design load the slab must be rated for, because it is the literal maximum the wall is built to hold.
Sizing and pad engineering
A vertical tank this size lives or dies by the foundation under it. Before you commit, run the Tank Sizing Calculator and read the Tank Sizing Guide to confirm 15,000 gallons in one body is the right call for your footprint and pad budget versus a cluster of smaller tanks. Then engineer the slab to the loaded number. Our concrete pad sizing guide walks the ACI 360R-10 framework and the ACI 318 boundary for above-ground polyethylene tanks - mandatory reading at 237,690 lb of potential rated load. If this is a private fire-protection reservoir, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
The common error on a tank this size is inspecting only the liquid side and assuming the wall is uniform. On tall vertical HDPE tanks, premature failures tend to originate at the vapor-saturated headspace, not down in the column where you can see and feel the liquid. Our guide on HDPE tank wall thickness at the vapor-saturated headspace explains why liquid-side inspection misses them and lays out the ASTM D1998 sizing logic operators should understand. For a full walkthrough of this exact size class, the 15000 Gallon Vertical Liquid Storage Tank buyer's guide covers specification and selection. See the technical drawing on this page for dimensioned views before you finalize layout.
This Snyder vertical storage tank ships LTL freight from the Lincoln, NE plant, quoted live to your ZIP - the 142 x 142 inch footprint and 234 inch height drive the freight class, which is exactly why the number is quoted live rather than listed. Get your number from the Freight Cost Estimator or call 866-418-1777. Standing 234 inches - 19.5 feet - tall on a square 142 inch base, this is an oversized load: confirm your overhead and door clearance, crane or offload reach, and site access before you book.
