The Snyder Industries 3000 Gallon Plastic Horizontal Leg Tank is built for one job: hauling and storing water across the farm, the worksite, or the nurse-trailer route. The cradle-style legs molded into the bottom let this tank ride on a flatbed or a frame-mounted skid and sit flat when parked, and the broad 92 by 142 inch footprint keeps a full load low and stable. It is a White polyethylene tank rated to a 1.0 specific gravity, which is the spec that tells you exactly what it is and is not meant to carry.
Will it work for your haul?
The numbers are straightforward. Capacity is 3,000 gallons of water; the tank measures 76 inches high, 92 inches wide, and 142 inches long. The figure that matters most on a horizontal leg tank is the loaded weight: filled to capacity with water this tank carries 25,020 pounds of contents. Size your trailer, axles, and tow vehicle to that number, not to the empty tank weight, and confirm your hitch and braking are rated for a full load before the first trip. At 76 inches tall the loaded tank also needs overhead clearance checked against your trailer deck height for any door, canopy, or bridge it has to pass under. If you are matching tank size to acreage, flow, or trailer payload, the Tank Sizing Calculator and the Tank Sizing Guide walk through it. Fitting sizes and locations are not in our spec data for this SKU, so confirm them against the technical drawing on this page or call before assuming an outlet size.
The 1.0 specific gravity rating - the mistake to avoid
This is a water-only horizontal tank. The 1.0 specific gravity rating means the wall thickness is engineered for the weight of water, and nothing denser. Loading it with a heavier liquid puts more strain on the walls than the tank was molded to take. If your plan involves anything beyond water, read the next section before you order - a different tank is the right answer.
Chemical compatibility
This tank is polyethylene rated to a 1.0 specific gravity. The resin grade here reads as HDLPE but is not yet confirmed - confirm HDLPE versus XLPE with us before any chemical service. At a 1.0 rating, this tank has no chemicals approved for service in our compatibility data; the liquids buyers commonly ask about for a tank this size all need a higher-SG tank than this water unit provides. That is not a knock on the tank - it is the honest line between a water hauler and a chemical hauler. The good news is that the most common "I also want to haul X" asks for a nurse-trailer operator need only a modest step up.
The chemicals fall into clear specific-gravity tiers, so you can self-select the right replacement tank:
- 1.35 SG tier: DEF (316SS fittings, EPDM gaskets) and Urea Solution (PP/PVC fittings, EPDM gaskets) - the smallest bump up from water, and the most likely ask on a nurse-trailer route.
- 1.5 SG tier: Acetic Acid (PP/PVC, EPDM), Aluminum Sulfate (PVC, EPDM), Calcium Chloride (PVC, EPDM), Ferrous Sulfate (PVC, EPDM), Magnesium Chloride (PVC, EPDM), Sodium Carbonate (PVC, EPDM), and Ozonated Water (PVC, EPDM).
- 1.9 SG tier: the strong acids and oxidizers - Sulfuric Acid (CPVC, Viton), Hydrochloric Acid (PVC, Viton), Sodium Hypochlorite (PVC, Viton), Phosphoric Acid (PVC, Viton), Ferric Chloride (PVC, EPDM), Ethylene Glycol (PVC, EPDM), and Potassium Hydroxide (PVC, EPDM), among others.
Fitting and gasket selection is concentration- and temperature-specific - always check the OEM chemical-resistance chart for your exact concentration and operating temperature, and see our full chemical compatibility reference before specifying a tank for anything other than water.
Freight
