The Enduraplas 210 Gallon Black Vertical Water Storage Tank (SKU TLV00210B) is a compact 48-inch-tall polyethylene vertical tank built for water storage where space is tight but capacity still matters. On a 40 x 40 inch footprint it holds 210 gallons of working volume for rural water reserve, irrigation supply, rainwater collection, or a fire-water reservoir feeding a private pump. The black color blocks light to slow algae growth, which is why it is a common pick for outdoor and partially shaded installs. It is built and rated for water storage.
Will it work for your site?
This is a vertical water storage tank with a specific gravity rating of 1.1, meaning the wall thickness is engineered to carry contents up to 1.1 times the weight of water. Filled with water, the tank holds about 1,751 pounds of liquid, and the structure is rated to carry a maximum contents weight of 1,927 pounds. Those two numbers matter for how you set it: plan the pad, footing, and any stand for the full filled weight, not the empty shell. The 48-inch height and 40 x 40 inch footprint let it tuck into pump houses, equipment sheds, and tight spaces where a taller or wider tank would not fit. One thing to confirm before you plan plumbing: this listing does not specify the installed fitting configuration, so call 866-418-1777 to verify the lid, outlet, and vent layout on the unit you are buying. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm 210 gallons covers your draw-down and refill cycle before you order.
Know the SG ceiling before you fill it
The mistake to avoid with this tank is putting the wrong liquid in it. At a 1.1 specific gravity rating, it is built for water and water-weight-class liquids up to that 1,927-pound contents limit. Heavier liquids — many chemicals, brines, and some liquid fertilizers run well above the density of water — exceed this rating and need a tank rated 1.5 SG or higher. Stay inside the water-service window this tank was designed for and you will get its full service life; push past the SG rating and you are over-stressing the walls.
Setting it up the right way
The other common mistake on a vertical tank this size is the foundation. A water-filled vertical tank concentrates close to a ton of load onto that 40 x 40 inch footprint — roughly 1,927 pounds spread across about 1,600 square inches — so it needs a level, continuously supported, smooth pad, not gravel high spots or a few timbers. Concrete handles that load easily; the real risk is point-loading on an uneven base. Our guide on concrete pad sizing for above-ground polyethylene tanks walks the ACI framework for getting that base right. After install, run a fill-and-hold check before you commit the tank to service; the hydrostatic test methodology guide covers water-fill discipline, pad-settlement monitoring, and fitting leak checks. If this tank is going into a private fire-protection setup, the fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection.
