The Snyder Industries 1100 Gallon Black Heavy Duty Vertical Storage Tank (SKU 8120000C34) is a polyethylene bulk storage tank built for serious water duty. It stands 55 inches tall on an 86-inch diameter footprint and carries a 1.9 specific gravity rating, which is heavy-duty territory for a polyethylene vertical tank this size. Full of water it weighs about 9,174 pounds, while the tank wall itself is rated to hold contents up to 17,431 pounds. If you are sizing a vertical storage tank, a rainwater cistern, or a static reservoir, the squat round footprint and low 55-inch height make this an easy tank to pad, fill, and service.
Will it work for your site?
Capacity is 1,100 gallons of usable storage. The 86-inch round footprint is wide and stable, and the 55-inch overall height keeps the center of gravity low and the fill port within reach without a tall ladder. The black resin holds up to UV exposure, which is why a black vertical tank is a common pick for outdoor water storage. The standout spec here is the 1.9 specific gravity rating: plain water sits at SG 1.0, so a full water load (9,174 lb) uses only about 53 percent of the wall's 17,431 lb rated contents capacity. That is real headroom. The same rated wall also means this tank can hold heavier-than-water solutions up to SG 1.9 (brine, liquid fertilizer, and similar), so if your service is not plain water, call 866-418-1777 to confirm chemical compatibility before you order. Before you build the slab, run the full-water weight and your planned fill level through our Tank Sizing Calculator and check the Tank Sizing Guide so the pad and any anchoring are matched to the load.
Pad and load planning
This is a heavy tank when full, so the foundation matters more than the tank. A flat, fully supported concrete pad sized to contain the entire 86-inch circular footprint is the right answer for a vertical storage tank carrying nearly five tons of water. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework so the pad supports the full footprint evenly. If this tank feeds a fire-water reserve, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For reclaimed or harvested water, the water reuse tank topology guide covers grey-water, rainwater, and HVAC condensate storage trains. If you need spill protection around a single-wall tank this large, the Snyder Captor double-wall freeboard guide covers the secondary-containment path.
The mistake to avoid
The common error on a tank this size is underbuilding the foundation. The 1.9 specific gravity rating describes the tank wall's strength, not a license to skip a proper pad. Set this tank on a partially supported or uneven base and you drive point loads into the polyethylene that it was never meant to carry. Build a pad that fully supports the 86-inch circular footprint and the tank will do its job for the long haul. The pack does not specify a factory fitting layout for this unit, so confirm the actual outlet and fitting locations against the technical drawing on this page, and order any bulkhead fittings and gaskets to match.
