The Enduraplas 150 Gallon Black Vertical Storage Tank is a 61-inch-tall polyethylene tank on a compact 30-by-30-inch footprint, built to hold 150 gallons of water or process liquid in a small mechanical room, pump house, or equipment yard. The black wall blocks light to discourage algae growth, and the vertical profile concentrates real storage into a 6.25-square-foot floor area when you do not have room to spread out. If you are sizing a vertical storage tank for fire-water reserve, rainwater catchment, or industrial reuse duty, this is a straightforward, single-purpose vessel.
Will it work for your application?
The tank measures 61 in. tall by 30 in. wide by 30 in. deep and is molded from polyethylene with a specific gravity rating of 1.9, so it is engineered to carry contents up to 1.9 times the density of water. Full of plain water at 150 gallons, the contents weigh about 1,251 lb; at the full 1.9 SG rating the tank is built to support up to roughly 2,377 lb of liquid. Use those numbers when you plan the pad and anchoring. Plan your clearance too: with the tank standing 61 in. tall, leave headroom above that for lid access and filling, and pour a level pad slightly larger than the 30-by-30-inch footprint so the base is fully supported. To confirm the size is right for your draw and refill cycle, run our Tank Sizing Calculator and read the Tank Sizing Guide. For the molded fitting and lid layout, see the technical drawing on this page before you finalize a plumbing plan.
Foundation and placement
A vertical tank carrying this much weight needs a flat, fully supported, level base. For a full water tank, the loaded weight lands well over half a ton, so the slab or pad has to bear the full footprint without flexing. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for getting that pad right. If this tank is going into a private fire-protection reserve, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
The mistake to avoid
The common error on a black vertical tank like this is treating the 1.9 specific-gravity rating as a license to store any heavy liquid. The SG number tells you the structural weight the wall is built to carry, not whether the polyethylene resists a given chemical. This unit is configured for water service. If you are aggregating grey-water, rainwater, or HVAC condensate, our industrial water reuse tank topology guide covers quality-banded storage trains, and the first-flush diverter sizing guide helps with rainwater catchment setup.
