The Enduraplas THV06250 is a 6,250-gallon vertical liquid storage tank standing 147 inches tall on a 120-by-120-inch footprint - a full-scale bulk polyethylene reservoir for water storage, fire-protection reserves, water reuse trains, and agricultural or industrial water supply. It arrives with a 16-inch lid for access and a 3-inch bolted fitting for plumbing, and its dimensions are verified. At 6,250 gallons, 147 inches tall, and 120 inches in diameter, it is a full-scale single-body vertical tank sized for bulk reservoir duty.
Will it work for your site
This tank is speced for water, which carries a specific gravity of 1.0. No higher-specific-gravity rating is confirmed in our data, so if you plan to store anything denser than water, confirm the liquid's specific gravity with us at 866-418-1777 before you order. Filled to capacity with water, the tank carries 52,125 pounds - the number that drives your foundation. A tank this size needs a properly engineered, level pad sized to its full 120 x 120 in footprint, so read our concrete pad sizing framework for above-ground polyethylene tanks before pouring. Confirm the 120-inch diameter clears your gates, doorways, and crane approach, and confirm the 147-inch height fits under any roofline or overhead obstruction. If you are still working out how much storage the application actually needs, our Tank Sizing Calculator and Tank Sizing Guide walk through demand, drawdown, and reserve.
The fittings and how they seal
The 16-inch lid gives you room for inlet plumbing, level sensors, and inspection access, and the 3-inch bolted fitting serves as your plumbing connection - confirm whether you are running it as inlet or outlet for your layout. Both the bolted fitting and the lid seal against gaskets, so confirm gasket material compatibility with your stored liquid before install. See the technical drawing on this page for the confirmed lid, fitting, and body dimensions.
The mistake to avoid
Vertical polyethylene tanks fail first at the vapor-saturated headspace above the liquid line, not at the wetted wall where routine inspection looks - a failure mode covered in our guide on HDPE tank wall thickness at the headspace and ASTM D1998 sizing logic. Inspect the upper wall and dome, keep the tank on a fully supporting pad, and never let a partial foundation bridge a load this heavy. For fire-water and rural reservoir duty, our NFPA 22 reservoir design guide covers sizing discipline and freeze protection; if you are aggregating grey-water, rainwater, or HVAC condensate, see our water reuse tank topology guide.
