The Snyder Industries 15,000 gallon XLPE heavy duty vertical storage tank (Snyder part 5370000N42) is built for large-volume above-ground water storage where a durable, high-strength wall matters. Molded in crosslinked linear polyethylene (XLPE) with a natural white translucency that lets you read the liquid level through the wall, it carries a 1.9 specific gravity rating - the tank shell is engineered to hold contents substantially heavier than plain water without derating for capacity. At 15,000 gallons in a single vertical footprint, it is one of the workhorse sizes for bulk fresh-water storage, fire-water reserve, and industrial process water.
Will it work for your site?
This vertical storage tank stands 234 inches tall - roughly 19.5 feet - on a 143 x 143 inch footprint. Plan your pad and overhead clearance around those numbers, since fill-line and roof or canopy clearance is a common oversight at this height, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm the capacity fits your draw-down and refill cycle. The molded-in fittings package includes a flange, a 12" x 26" fitting, an 18" PE threaded/vented fitting, a flat fitting, and a manway with 15" access - see the technical drawing on this page for exact fitting placement and elevations before you finalize plumbing and venting. Because XLPE cannot be thermally welded like HDPE, all connections run through these molded fittings, and the bolt-on manway is your gasketed inspection and cleanout access - plan your inlet, outlet, overflow, and vent routing around those fixed points.
Weight and foundation
Filled with water this tank carries roughly 125,100 lb, and at its full 1.9 SG rating the contents can reach about 237,690 lb - a delta of more than 112,000 lb that is exactly what the crosslinked wall and 1.9 rating are built to hold. Size the supporting pad for the 237,690 lb rated maximum, not the 125,100 lb water case. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for a flat, fully supported base - the single most common and most expensive mistake with a tank this size is under-building the foundation. If this is going into rural fire-protection service, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and freeze protection for cold-climate sites.
XLPE vs standard HDPE
The crosslinked resin is the reason to choose this tank over a standard HDPE vertical of the same size. Crosslinking gives the wall greater impact resistance and a higher tolerance for heavier contents, which is why it carries the 1.9 SG rating. If you are weighing the two constructions, our breakdown of Snyder XLPE vs HDPE explains when the upgrade earns its keep. For water reuse or blended-source storage trains, the industrial water reuse tank topology guide shows how a tank this size fits into a staged system.
This tank ships by LTL freight from the Snyder plant in Lincoln, Nebraska, quoted live to your ZIP. A 15,000 gallon vertical is an oversized load, and freight from central Nebraska varies sharply with distance to your site, so get an accurate number through our Freight Cost Estimator or call 866-418-1777 to arrange delivery and offloading. Our team can confirm fitting layout, pad requirements, and lead time before you order.
