The Snyder Industries 4000 Gallon ASTM XLPE Vertical Storage Tank is a heavy-duty crosslinked polyethylene vertical tank built for demanding bulk water and higher-density liquid storage. Molded in natural white crosslinked linear polyethylene with a 1.5 specific gravity rating, this vertical storage tank holds a nominal 4,000 gallons in a footprint of roughly 120 by 120 inches. The crosslinked (XLPE) resin gives you a tough, impact- and stress-crack-resistant wall that stands up to years of outdoor storage duty. Confirm the tank height and diameter against the technical drawing on this page before you finalize your site layout or overhead clearance.
Will it work for your site?
Plan your pad and anchoring around real loaded weight, not just capacity. Filled with water, this tank carries roughly 33,360 pounds, and its 1.5 SG rating means it is engineered to hold contents up to about 50,040 pounds at full rated density. That is the reason to step up to XLPE 1.5 over a water-only 1.0 SG tank: it lets you store liquids heavier than water, including many brines and solutions, without giving up wall integrity. Fittings on this unit include a flange, an 18 inch PE threaded and vented fitting, and a manway with 15 inch access. That 15 inch manway access is your service constraint, it governs whether a person or pump can enter for inspection and cleaning, so verify it works for your maintenance plan. Check the exact fitting locations and elevations against the technical drawing before you set your plumbing.
Sizing and load planning
Because a 4,000 gallon vertical tank is a serious structural load, size the tank and the pad together. Our Tank Sizing Calculator and Tank Sizing Guide help you match capacity to your real draw and refill cycle, and the concrete pad sizing framework walks the ACI 360R-10 and ACI 318 boundary for above-ground polyethylene tanks. If this XLPE tank is headed for fire-protection duty, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate reuse, the water reuse topology guide lays out quality-banded storage trains.
The mistake to avoid
The most common error on a tank this size is undersizing the foundation or setting it on uneven ground. A partially supported base concentrates stress and can crack the wall over time, so verify your pad is flat, level, and rated for the full loaded weight before filling. Match your inlet and outlet gaskets and bulkhead hardware to the flange and 18 inch PE threaded fitting sizes shown on the drawing rather than assuming a size, and spec a gasket material appropriate to your stored liquid.
