The Enduraplas 1100 Gallon Black Vertical Water Storage Tank is a polyethylene vertical tank built for bulk water storage where a compact 60-inch footprint matters. At 97 inches tall on a 60 x 60 inch base, it holds 1100 gallons and carries a 1.1 specific gravity rating, so it handles water and water-density liquids with margin to spare. The black wall blocks light from reaching the water, which suppresses algae growth in outdoor service — a practical reason this color gets specified for above-ground storage. If you have been searching for a vertical water storage tank that fits a tight pad without sacrificing volume, this is the size that balances height against ground area.
Will it work for your site?
This is a 1100-gallon vertical tank measuring 97 inches in height on a 60 x 60 inch footprint. The 1.1 specific gravity rating means the wall is rated for liquids up to 1.1 times the weight of water, which covers water and water-density service comfortably. Plan your pad and access clearances around the 60 x 60 inch footprint and the 97-inch overall height. Fitting sizes and inlet/outlet locations are shown on the technical drawing on this page — review them before you finalize plumbing, and call 866-418-1777 if you need a fitting configuration confirmed before you order. To confirm this capacity matches your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide.
Weight, pad, and install planning
Full of water, this tank weighs about 9,174 pounds, and the wall is rated to carry contents up to 10,091 pounds at its 1.1 specific gravity limit. Spread across the 60 x 60 inch base (3,600 square inches), the rated load works out to roughly 2.8 pounds per square inch of bearing pressure — a real input you can hand to whoever engineers the foundation. A flat, fully supported pad under the entire footprint is not optional on a tank this size. Our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks, and once the tank is set, our hydrostatic test methodology guide covers the water-fill acceptance and pad-settlement monitoring that catch problems before the tank is in service.
Common applications and the mistake to avoid
At 1100 gallons, this vertical storage tank lands in the size range buyers weigh for rural fire-water reserve and for water reuse. If fire protection is the use case, our fire-water reservoir design guide works through NFPA 22 sizing and cold-climate freeze protection; if you are aggregating grey-water, rainwater, or HVAC condensate, the industrial water reuse topology guide covers quality-banded storage trains. The mistake to avoid is reading the 1.1 specific gravity rating as a green light for chemicals heavier than water. The headroom over 1.0 covers water-density service, not heavier liquids — keep this tank in water service unless the OEM chemical-resistance chart confirms a specific liquid for this resin. The other common miss is undersizing the foundation: a vertical tank that settles unevenly under nearly five tons of water load will stress fittings and seams long before its time, so size the pad for the full 10,091-pound rated load, not the empty tank.
