The Enduraplas 6011 gallon black vertical storage tank is a heavy-capacity above-ground bulk water tank molded in black polyethylene, standing 110 inches tall on a 144 x 144 inch (12 x 12 foot) footprint. It carries a 1.9 specific gravity rating, so the wall is built to hold contents substantially denser than water while running plain water or general non-potable storage. At 6,011 gallons it sits in the vertical storage tank tier used for rural fire-water reservoirs, irrigation supply, industrial process water, and bulk site storage where footprint and static load matter more than portability.
Will it work for your site?
Full of water this tank holds roughly 50,132 pounds, about 25 tons of static load. At the 1.9 rated specific gravity the maximum rated contents weight climbs to about 95,250 pounds, close to 47.6 tons, and that worst case is the number your foundation has to be sized to, not the water figure. A 12-foot square footprint under that kind of load needs a properly engineered slab, not compacted gravel alone, so plan the pad before the tank arrives. Work the numbers with our Tank Sizing Calculator and Tank Sizing Guide, and review the concrete pad sizing framework before you pour. The technical drawing on this page gives overall dimensions for your site layout; call us at 866-418-1777 to confirm fitting placement before you finalize plumbing.
Where it fits in your water system
A 6,000-gallon black vertical tank is a common backbone for a private fire-protection reservoir on rural and remote sites, feeding the pump per your design. Our guide on fire-water reservoir tank design walks the NFPA 22 sizing discipline and cold-climate freeze protection that govern that role. The same tank anchors an industrial water reuse train for grey-water, rainwater, and HVAC condensate aggregation, or a harvesting setup like the one in our rainwater harvesting guide.
The mistake to avoid
The black color is the point, not a downgrade. Black polyethylene blocks light and suppresses the algae growth that plagues translucent and light-colored tanks in outdoor water storage, which is why it is the right pick for a standing reservoir. Do not read the 1.9 specific gravity rating as clearance for aggressive chemical service on a water-classified tank. If your application shifts toward a chemical, confirm the exact resin and gasket requirements against the OEM chemical-resistance chart before you fill it. And do not underbuild the foundation, because a tank this heavy is unforgiving of a settling or uneven pad.
