The Enduraplas 3000 Gallon White Horizontal Sump Bottom Leg Tank is built for over-the-road and on-yard hauling of heavy liquids that round vertical tanks can't carry safely. It holds 3,000 gallons in a horizontal leg-tank body that measures 130 inches long, 87 inches wide, and 93 inches tall, riding on integrated legs. The sump bottom drains toward a low point, which on a haul tank does more than ease cleanout: it lets you draw down to near-empty without tipping, so you carry less residual heel and fight less slosh on a partial load than a flat-bottom horizontal would. The natural white polyethylene shell carries a 1.9 specific gravity rating, the number that matters most on a haul tank because it sets how heavy a liquid you can fill before the walls are overstressed.
Will it work for your liquid and load?
Run the weight math before you commit. Filled with plain water at SG 1.0, this tank carries roughly 25,020 pounds of contents. At its full 1.9 SG rating it is built to hold up to 47,538 pounds of contents, so a heavier-than-water fluid stays inside the design envelope as long as your liquid's specific gravity does not exceed 1.9. The 87.0 x 130.0 inch footprint is what you'll confirm against your trailer deck or pad. To match this tank to your actual fill volume and fluid weight, use the Tank Sizing Calculator and the Tank Sizing Guide so you size to weight, not just gallons. See the technical drawing on this page for fitting locations and the sump detail.
Chemical compatibility
This tank is molded polyethylene with a 1.9 SG rating. The resin is recorded as HDLPE but flagged for confirmation, so for plain water, DEF, or glycol haul service the resin question doesn't gate your purchase; it only matters before aggressive chemical fill, where you should confirm HDLPE versus XLPE with us first, since the two resins behave differently with strong media. At 1.9 SG a wide range of heavier industrial liquids stay within the structural envelope. A simple way to read the OEM chemical-resistance chart below: most media run on EPDM gaskets with PVC fittings; strong acids and oxidizers step the gasket up to Viton; Peracetic Acid uniquely needs Aflas; DEF, Peracetic Acid, Propylene Glycol, and Zinc Orthophosphate need 316SS wetted metal; and Sulfuric Acid at full 98% steps the fitting up to CPVC. Two media are concentration-sensitive: Sodium Hypochlorite is rated below 16.5% (PVC, Viton) and Sulfuric Acid at 98% (CPVC, Viton) — confirm your strength before you spec hardware. Compatible chemicals from the chart include Acetic Acid at 60% (PP/PVC, EPDM), Aluminum Sulfate at 50% (PVC, EPDM), Calcium Chloride at 40% (PVC, EPDM), DEF at 32.5% (316SS, EPDM), Ethylene Glycol at 100% (PVC, EPDM), Ferric Chloride at 50% (PVC, EPDM), Ferric Sulfate at 60% (PVC, EPDM), Ferrous Sulfate at 20% (PVC, EPDM), Hydrochloric Acid at 37% (PVC, Viton), Hydrofluoric Acid at 48% (PP/PVC, Viton), Hydrofluosilicic Acid at 26% (PP/PVC, Viton), Hydrogen Peroxide at 50% (PVC, Viton), Magnesium Chloride at 30% (PVC, EPDM), Peracetic Acid at 30% (316SS, Aflas), Phosphoric Acid at 85% (PVC, Viton), Polyaluminum Chloride (PVC, EPDM), Potassium Carbonate at 50% (PVC, EPDM), Potassium Hydroxide saturated (PVC, EPDM), Propylene Glycol (PP/316SS, EPDM), Sodium Bisulfate (PVC/PP, EPDM), Sodium Bisulfite (PVC/PP, EPDM), Sodium Carbonate at 30% (PVC, EPDM), Sodium Thiosulfate at 40% (PVC, EPDM), Urea Solution at 50% (PP/PVC, EPDM), Zinc Orthophosphate (PP/316SS, EPDM), and Ozonated Water up to 10 PPM (PVC, EPDM). Match your fitting and gasket material to the chemical exactly as listed, and always verify against the OEM chemical-resistance chart for your specific concentration and temperature.

The mistake to avoid
The expensive error on a haul tank is filling to gallons instead of to weight. Loaded with water this is a 25,020-pound load; with a 1.9 SG liquid it can reach 47,538 pounds of contents. Confirm your fluid's specific gravity stays at or under 1.9 — and note that 1.9 is already the heaviest-duty rating offered here, so there is no higher-SG tank to step up to; your only constraint is keeping your liquid at or below that number. Don't assume the resin either: because it is flagged HDLPE with a question mark, confirm HDLPE versus XLPE before any chemical fill, and pair the correct PVC, CPVC, PP, 316SS, Viton, EPDM, or Aflas hardware to your media. If this tank rides a trailer, also review our guides on DOT and 49 CFR scope for applicator and leg tanks for fertilizer and portable utility tanks under 49 CFR 173.5 before you haul.
